1 Introduction 1

1 Introduction The Engage3D software product is designed to fast track your work and map production. These tutorials take you through the steps required to produce a variety of displays with Engage3D. The tutorials utilise example data installed when the software is loaded onto your computer.

Tutorial Features

The tutorials illustrate the enhanced functionality of the Engage3D product suite that can be used to create professional quality maps, modify data objects, produce graphs for analysis and manipulate table data.

Data types include:

• High resolution aerial photography.

• Environmental data of wind speed and air quality.

• Infrastructure data for streets, roads, railways, parks.

• Theoretical datasets such as proposed wind farm sites and traffic accident data.

• 2001 Census data

Data Source

The tutorial datasets feature regions around Port Talbot in South Wales along with generic United Kingdom datasets.

Datasets have been acquired from the following sources:

• OS Mastermap Topography sample layer, Crown Copyright 2007.

• Aerial imagery and DEM derived from datasets provided by BlueSky Ltd, Copyright BlueSky 2007.

• StreetPro plus data and Census Primary Pack 2001 data was provided by MapInfo Ltd, Copyright MapInfo 2007.

• Windspeed data provided by UK Department of Trade and Industry. http://www3.dti.gov.uk/renewables/technologies/windspeed/

• Air Quality data derived from the UK Air Quality data archives http://www.airquality.co.uk/archive/data_and_statistics_home.php

Engage3D 2013 Tutorials 2

Tutorial Data Installation

The tutorial dataset is installed into the following locations:

C:\Documents and Settings\All Users\Application Data\MapInfo\Engage3D\ Engage3D_Tutorial on Windows 2000 and XP operating systems or

C:\ProgramData\MapInfo\Engage\Engage3D_Tutorial on Windows 7 and 8 operating systems.

All references to the dataset locations in the tutorial exercises are relative to the Engage3D_Tutorial folder, where the tutorial data is located. An additional folder Workspaces is used to save MapInfo Professional workspaces, allowing the recommencement of tutorials at a later stage.

Note With all the tutorial data located in the Engage3D_Tutorial folder, to save time navigating through the various local folders, use the MapInfo Professional default options for folder locations. Within MapInfo Professional select the Options>Preferences>Directories menu and click the Modify button after highlighting the Tables item. Navigate to the Engage3D_Tutorial folder. Repeat this procedure for Workspaces.

Note Located throughout the tutorial documentation are numerous buttons, these occur within the various toolbars of Engage or MapInfo Professional. If these buttons are not displayed, navigate to the Engage>Toolbars menu item and enable any of the required toolbars from the selection of Engage3D, Map Window, Object Editing and Map Making.

Hint For all tutorials we recommend changing your MapInfo Professional map window settings to uncheck the Automatic Raster Zoom Layering option. This will prevent you having to use the Display Within Zoom Range check box every time raster imagery is opened in a map window.

2 Map Making Tutorial 3

2 Map Making Tutorial The objective of this tutorial is to create a professional quality map for presentation purposes, complete with a location map, legend and titleblock ready for printing.

Professional Quality Map Production

Step 1 – Open map layers

1. From the MapInfo Professional menu, choose File>Open…, selecting the following tables from the \Engage3D_Tutorials\Map Making folder:

UK OUTLINE, PORT TALBOT AREA, GAZETTEER, RAILWAY, MAJOR ROADS, LOCAL ROADS, WATER, URBAN

Verify the map window is located in the British National Grid [EPSG:27700] projection; to confirm navigate to Engage>Map Window>Current Mapper Projection. To modify the map window projection navigate to Map>Options>Projection and change accordingly.

To view the map objects around the Port Talbot region select the Change View option from MapInfo Professional Main toolbar. Enter the following details into the Change View dialog. Click OK.

Change View dialog and map window parameters

Step 2 – Reordering and grouping layers the ELC

2. With the Enhanced Layer Control (ELC) open check the order of

each table. Make sure the tables are organised as seen in the image below.


Enhanced Layer Control and Port Talbot map layers

Note To re-order a map layer make sure it is highlighted, hold down the left mouse button and drag the layer into the correct location. When you release the mouse button, the layer is relocated.

3. With numerous map layers now present in the map window, rename it to display a more simplified convention. Highlight the current map window title in the ELC, right-mouse click to display the Window Properties dialog. Within the Title text box, type PORT TALBOT INFRASTRUCTURE. Accept other defaults and click OK.

Window Properties dialog with edited map window title


4. With several map layers present in the map window it is beneficial to

group them into categories. To create grouped categories use the Display Groups button located at the bottom of the ELC window. Make sure the Display Groups button is depressed in order to create new groups.

5. Highlight the Default Group layer in the ELC, right-mouse click and select the Add Group option. Name the new group Infrastructure and drag and drop the layers RAILWAY, MAJOR ROADS and LOCAL ROADS into this group. Add another group named Topography for the layers WATER and URBAN. Replicate the grouping in the ELC window as seen in the image below.

Grouped layers in ELC dialog


Hint At this point, you may wish to save the workspace for future reference. Save the workspace using the File>Save Workspace MapInfo Professional menu option. Name the workspace PORT TALBOT INFRASTRUCTURE MAP.WOR and save in the \Engage3D_Tutorials\Workspaces directory.

Use Engage>Table and Workspace Utilities>Favourite Workspaces to add this workspace to the frequently used workspaces list.

Step 3 – Add text labels

Adding labels to a map for printing requires a methodical approach to get the required result. If you place labels on the map window and print, the labels often have an inappropriate size and require additional customisation. Engage solves this problem by allowing you to label a map layer at a set point size and scale.

6. Select Engage>Text>Label Creator. Within the dialog, select Table Gazetteer and Column Name. Under label Style select label Size 9 pts for a Map Scale 1:25,000. Click on the Text Style button and check the Halo option, click OK.


Label Creator dialog

Text Style dialog

Note When using the Halo background, the size of the text appears smaller as the full height of the text incorporates the halo as part of the text size.


It is possible to save the text labels to any editable table or into a newly created table, unlike MapInfo Professional where labels are always saved to the Cosmetic Layer.

7. In the Output section, select Table option and save the labels to a table called GAZETTEER LABELS within the \Engage3D_Tutorials\Map Making folder. To create labels click the Generate button.

Note If you wish to verify the label size and view before saving to a MapInfo Table you can output to the Cosmetic Layer. The Clear Cosmetic Layer button enables a quick deletion of the labels on the Cosmetic Layer when numerous attempts are required to get the correct labels.

Note Another option is to choose an offset for the labels. To apply an offset click the Advanced Options button and specify an offset to the north, east, vertical position of the object centroid.

8. Open the table PUBLIC LOCATIONS and use the same procedure as above to create name labels with font size 9, red text, bold with a background halo and save to a new table named PUBLIC LOCATIONS LABELS.

9. If you wish to modify all text objects use the Engage>Select>By Map Object Style tool. Keep the default boxes checked and select OK, to select all labels in the layer. Use Engage>Text>Format to change the map scale or text style. Select OK when finished.

Step 4 – Create map legend

A legend can be created with user-defined map layers. The legend is fully customisable.

10. Click on the Legend button or navigate to Engage>Map

Layout>Create Map Legend to open the Create Legend 1 dialog.

11. With the Create Legend 1 dialog open hold down the CTRL key while using the left mouse-button to select the tables shown below. Select OK when finished.


Create Legend 1 dialog with selected map layers

12. Within the Create Legend 2 dialog specify which columns of attribute data which are to be displayed in the legend. Fill in the dialog as seen in the image below.

Create Legend 2 dialog with specified legend entries

13. Check the Specify Order box for the MAJOR ROADS table to set the order of legend items for this layer. If your map window does not display the full extents of a table, and you wish to create a legend for all items in the table, do not place a tick in the box for Legend from objects in map window only. Depending on the number of features in your legend you may want to select either 1 or 2 columns from the Legend Style.


14. To specify the font size for the legend text, click the Styles button and select the font style button next to Title Line. Choose point size 24. Repeat the process for Sub-Title Line, select point size 18. Click the Text Line 1 and Text Line 2 font style buttons and choose point size 14. Click the OK button and enter the legend table name PORT TALBOT INFRASTRUCTURE LEGEND into the \Engage3D_Tutorials\Map Making folder.

Legend box text style specification dialog

15. The legend order window for the MAJOR ROADS layer will be displayed. The roads should be displayed in Alphabetical order (asc). Select OK when finished.

16. The legend will be displayed in a new map window. Minimise the legend window and make the infrastructure map window active before proceeding to the next step.


Port Talbot Infrastructure Legend window


Step 5 – Generate scaled hardcopy output

The Scaled Output tool can produce a professional map output into a MapInfo Professional layout window. Map grids, titleblock, scale bar and legend layers can be added to the scaled output.

17. Select the Scaled Output button or choose the Engage>Map

Layout>Create Scaled Output menu option. Ensure the map window to display is active.

Scaled Output dialog

18. Within the Scaled Output dialog select 1:25,000 from the Map Scale pull-down list. You can choose from a variety of predefined scales or create your own custom scale. Under Frame Setup, select A4 Landscape from the pull-down list. To modify the default settings, select the Configure button to alter the map frame and printing margins etc.

Note The non-printing margins may need to be adjusted depending on the printer driver installed. You can determine if adjustments are required by completing the scaled output exercise and observing the resulting layout window. If portions of the map are in the non-printing margins of the layout, you will need


to return to the Configuration menu and adjust the non-printing settings. If a non-printing margin is changed this will need to be compensated for by decreasing the frame width.

19. Ensure the Draw Grid option is selected and the TitleBlock is specified as Titleblk. The Scalebar should be selected as ScaleBar 1. Select OK when finished.

Scaled Output area frame

20. The map window will zoom and a transparent polygon, representing the area to be plotted at 1:25,000 scale, will appear in the map window. Left mouse-click inside the frame and drag to cover the town of Port Talbot. The parameters can be respecified by selecting the Scaled Output>Re-specify Parameters Option if required.

21. When satisfied with the frame position, select Scaled Output>Accept Map Position option. The map window resizes to the area of the transparent map frame. The Overlay Map Grid dialog box appears.

22. Replicate the parameters displayed in the Overlay Map Grid dialog as seen in the image below. Change Grid Style to Lines with a solid dark grey line. Check the Place labels in mask polygon outside map frame option and Display Labels at Left and Top. The grid will be saved by default as an Autogrid in the Engage3D_Temp folder. To permanently save the grid select Save As and navigate to \Engage3D_Tutorials\Map Making folder, name grid PORT TALBOT GRID. Click OK to proceed.


Scaled Output Map Grid dialog

23. The TitleBlock and ScaleBar Options dialog is presented. Replicate the parameters as seen in the image below. From the Titleblock Position list, choose Bottom Right Outside. Keep the default ScaleBar option as Show ScaleBar in Titleblock. Set the Display List of Layers in map to No List.

24. The TitleBlock will be saved by default as Titleblk in the Engage3D_Temp folder. To permanently save select Save As and navigate to \Engage3D_Tutorials\Map Making folder, name the titleblock as PORT TALBOT TITLE. Click OK to proceed.


Titleblock and scalebar options dialog

Note If the Layout Window shows an incorrect page size, select File>Page Setup with A4 and Landscape parameters. Click OK to accept the Page Setup parameters. This procedure ensures that the MapInfo Professional Layout Window is set to the size and orientation required.

Step 6 – Add scaled frame to layout

25. Make the Legend map window the front window. Click on the Add

Scaled Frame to Layout button or navigate to Engage>Map Layout>Add Scaled Frame to Layout and fill in the dialog as seen in the image below. Click OK to proceed.


Add a scaled legend frame to the layout

26. The legend is added to the layout window. Take a moment to examine the legend position with reference to the layout measurements and the information that was entered in the dialog. This will help you understand how Add Scaled Frame to Layout works. Paper measurements that appear along the side of the layout window are in centimetres.

Step 7 – Create location map

The final task is to add a location map to the final layout window.

27. Within the ELC right click and select the Open Table option. In the Open dialog select the UK OUTLINE table from the \Engage3D_Tutorials\Map Making folder and place into a new map window (select New Mapper from the Preferred View pull-down list).

28. Select the Engage>Object>Draw by Coordinates menu option.

Choose Point as the Object Type, click on the Object Style button and select a red star with a size 18. Make sure the XY Units are set to Metres and click the Enter Coordinates button. Enter the following point coordinates:

Xm = 278726 Ym = 187303

Within the Draw by Coordinates dialog select Cosmetic Layer from the Draw onto pull-down list. Click OK to close the Draw Point dialog.


Open Table menu within ELC

29. Navigate to Map>Save Cosmetic Objects to save the point to a new table called PORT TALBOT LOCATION POINT in the \Engage3D_Tutorials\Map Making folder. The new point is visible in the UK Outline map window.

Step 8 – Add location map to the Layout Window

30. Make the Location map window the active window. Select Engage>Map Layout>Add Scaled Frame to Layout. Fill in the dialog with the following parameters and click OK.


Add a scaled location map frame to the layout

The location map is added to the Layout Window.

From the MapInfo Professional Drawing toolbar, click on the Text Style button, and choose a Font Size of 8. Next click on the Text button, position your cursor in the bottom left corner of the location map (in the Layout Window) and type LOCATION MAP.

Step 9 – Exit Scaled Output and plot map

31. Select Scaled Output>Exit Scaled Output. A dialog box appears prompting you to save the map grid, titleblock, scalebar and a workspace. If you want to plot more copies of your map later, you should tick all boxes and enter appropriate table names to save the titleblock, scalebar and map grid. If you do not save the tables and workspace you will have to go through the scaled output process again to re-create the map.


Saving the Scaled Layout parameters

32. Print the displayed scaled map by selecting File>Print. An example map with titleblock, legend and location map is shown below.

Map with titleblock, scalebar, legend, and location inset

Note Frames which have been added into the Layout Window can be dragged into a new location with the mouse cursor. To align frames highlight the respective frames and select Align Objects by right clicking on the Layout Window.


Step 10 – Apply Cursor Position (Optional)

The Cursor Position tool can be used to display the same coordinate in two or more open map windows.

33. Position the PORT TALBOT INFRASTRUCTURE map window and the UK Outline map window so that both are visible in the MapInfo Professional screen. Enable the Cursor Position tool from Engage>Map Window>Cursor Position. A new Cursor Position menu item appears on the MapInfo Professional menu. Select Cursor Position>Cursor Position On. Alternatively, select the Cursor Position on button from the toolbar. The cursor changes from an arrow to a crosshair. To select the symbol, click the Symbol button and choose a blue cross size 18.

34. The Cursor Position dialog is displayed so you can choose which windows are to have the interactive cursor position displayed. Click on Select all or to choose each window separately, place a tick next to the desired windows in the list. Select the box next to Pan mapper to show cursor position so that the geographic position of the identified position is shown if it is not visible in the map window. Click OK.

Cursor Position dialog

The cursor position symbol appears in the PORT TALBOT INFRASTRUCTURE map window and the map of the UK outline automatically connecting the geographic locations at the position that was selected.

35. To remove the Cursor Position select Cursor Position>Cursor Position off… or click on the Cursor Position Off button in the


MapInfo Professional tool bar.

Step 11 – Map Linking (Optional)

Map Linking provides the ability to synchronise views between all selected map windows. Any pan or zoom updates in one map window are automatically communicated to all other map windows linked by the function.

36. Make both the UK Outline and the Port Talbot Infrastructure maps visible and select Engage>Map Window>Map Linking. You can also start the Map Linking option from the pop-up menu when you right-mouse click in any active window.

37. From the Map Linking dialog select the windows to be linked by either ticking the box next to each open table or by selecting the Select All button. Choose an option for the link method from either Fixed Extents on maps or Fixed Scale on maps. Click OK.

Map Linking dialog

38. To Unselect all linked tables in the Map Linking dialog click the Unselect All button. Alternatively, use the right-mouse click pop-up menu in any linked window and click on the Link this map option


3 Batch Printing Tutorial EngageBatchPrinting is a Map Generation tool designed for the MapInfo Professional platform. Once set up, the application allows users with very little GIS, mapping or even computer skills to generate quality maps over their area of interest in either batch or single mode.

Essentially, EngageBatchPrinting is designed to produce a product that is similar to the street directories available for most major cities. The big difference is, users are not limited to one theme for their maps (e.g. streets). Instead, you can have any detail on the maps you like from detailed property maps through to state wide area maps. The commands in EngageBatchPrinting are designed to support the three forms of output generated by the product. Like the three main sections in any street directory, these are:

• The Key Map which is an overview map showing the area of interest overlaid by all the required map sheet boundaries. Using this map the user can quickly locate the area of interest, determine the map sheet it is on, then go directly to the required map page.

• The Index which is a list of features located on the maps. The list shows all the required features in alphabetical order along with its Locality Name, Map Sheet Name and Number and Grid Reference. Unlike the street directory though, users can generate any number of indexes. For example, a local government authority could have one index for street, one for Lot on Plan details, one for parks, etc.

• The Individual Map Sheets showing one map per page. The user has all the commands needed to set up and customise these maps so they appear exactly as the user wants them to look. Once created, each Map Template is stored under a single user-friendly long name. At the time of output, the users can then simply select which style they want the maps to be in then click the button to start map output.

Step 1 – Generating and Printing a Map Sheet

1. From the MapInfo Professional menu, choose File>Open…, selecting the following workspace from the \ Engage3D_Tutorials\EngageBatchPrinting folder:

ENGAGEBATCHPRINTING_TUTORIAL.WOR

2. Navigate to the Engage>EngageBatchPrinting menu.

3 Batch Printing Tutorial 23

EngageBatchPrinting menu

3. Navigate to EngageBatchPrinting>Open Map Series to open the CustMaps map series layer located in \Engage3D\MapShop\MapSeries. This layer consists of a series of attributed polygons outlining the required map sheet boundaries. Display labels for this layer, and set the label field as the Name field.

Note Map Series can be created by the user via the Generate Map Series menu option.


Select Map Sheet to print

4. To print a single map sheet, select the target map sheet boundary from the map window (e.g. the Springfield map sheet boundary is selected above). Then select the EngageBatchPrinting>Print Map Catalog>Print Map Sheets menu option.

5. On the Map Catalogue Plot dialog ensure the Map Series is set as CustMaps, and the Selection Only tick box is enabled.

Note The Selection Only is recommended for initial finessing and customization of one or just a few layouts. If the Do All Maps option is enabled, all map sheets in the map series will be consecutively produced (in order of the Print in order of field further down the dialog).

Leave the Map Title as <Use Map Name as Title>.

Specify the Template as Map Series Map (A4 Portrait).


Note A number of page-size specific default templates are available; these can be customized with the Edit Existing Map Template option, or new templates created with Generate New Template.

Map Catalogue Plot dialog

Set the Map Scale to Same zoom width as on map.

Leave the Zoom Layers on Maintain Zoom Layering Settings.

Enable the View/Edit layout before printing the Plot option.

Set the following the following two options to Map Name.

6. Click the OK button on the Map Catalogue Plot dialog. A number of intermediate map windows will be created, followed by a layout window.


Map Sheet produced

7. The Map Output toolbar will be visible. Click the Print Current Map button to print the layout window.

If multiple map sheet boundaries were previously selected, two additional toolbar buttons will be available:


Generate Next Map button to navigate to the layout window for the next selected map boundary.

Batch Mode button to automatically generate and print all remaining selected map boundary layouts.

Note If the View/Edit layout before printing the Plot option had been disabled in the Map Catalogue Plot dialog, pressing OK at the end of that dialog would have sent the output directly to the printer with no preview layout, ideal for large batch printing jobs.

8. Click the Stop Outputs of Map button to close the layout window and

return to the original source data map window.

Refining and customizing the output Map Sheet

Have a look at the map you have just printed and we will go over some of the detail it shows. First there are two areas on the output we have control over. These are the map area itself (including all grid numbers, ticks, lines etc) and second, the marginal information which is all the other work around the map.

Step 2 – Map Area Customisation

9. Lets look at the map area itself. When you produce a Map Sheet, the dialog has a Styles button at the bottom left corner that allows you to change the grid and referencing numbering styles.

User defined map styles


10. On this Set Map Style dialog you can see that there are many optional components that can be drawn over the map. The sample map above displays the results you will get from these settings. Let’s look at a few of these settings.

Note The various settings in this dialog are saved to the MapShop.ini file, discussed in detail in Appendix D of the Engage User Guide.

• Neatline: The line that is drawn around the map sheet which in the sample above fits the map edge exactly (0 mm offset). You can also change the style of the line it draws if you like (the thick dashed casement style looks good). Obviously there is no spacing on a neatline so the last column is n/a.

• Join Edge: Disabled here but if enabled, will change how the edge of the map appears.

• Corner Marks: Disabled here but if enabled, will change how the edge of the map appears.

• Grid Ticks: The length of the tick marks is set to 4mm and the spacing for the tick marks is set to 200 apart. 200 what you ask? The values used in the Spacing column are the map units of the projection the map series is in (eg metres on metric projections). Therefore, in this case, they are 200 metres apart. You can also set the line style for the tick marks.

• Grid Crosses: Also disabled but they simply show crosses representing the intersections of the internal grid lines. You can use Grid Crosses with or without grid lines.

• Grid Lines: Enabled on this map and appear as dotted lines inside the map area. Grid lines would typically have the same spacing as the grid ticks and are drawn in the style selected on the dialog. They have no size because they go right across the map sheet to the neatline.

• Ref: Enabled above so we see them on the map around the edge. These are the A, B, C etc and 1, 2, 3 etc. The style for this item is a font picker. The offset is the distance out from the real neatline.

Note The style, density, order and direction of the alpha-numeric reference grid system can be controlled via options in the EngageBatchPrinting Configuration dialog.

• Corner: Also enabled above and are set to only 1 mm out.


11. As we can see from the sample map above, only the grid numbers in the bottom left of the map are shown as full numbers. The rest of the numbers are shortened, for the purpose of reducing clutter around the map. The first two settings in the Grid and Reference Number Styles section of the dialog can be used to specify which digits to show in the grid numbers.

Grid reference and styles dialog

12. The normal map convention is to show the digit that is changing plus the next digit as well. In the above example we are using 200 metre spacing, so I want to show o,oo0,0oo which is the third and fourth digits (from the right hand side of the number). The big 0’s indicate the digits that will be shown on output.

13. The second last control on the dialog is a radio group that allows you to set the Reference # to be either aligned to the Grid or at the fixed spacing set in the INI file. In the above example, the reference numbers are set to align to the grid so that the numbers and letters are placed evenly between the grid numbers.

Note The style, density, order and direction of the alpha-numeric reference grid system can be controlled via options in the EngageBatchPrinting Configuration dialog.

14. The final setting rotates the reference number to face inwards on the map.

Step 3 – Margin Customisation

Now let’s look at the marginal detail. Along the bottom of this sample map is a whole lot of text and graphics which improves the appearance of the map and provides additional information to the user. How did it get there and how can you change it to suit your needs? Well, it's all in the templates.

15. The template in this case Map Series Map A4 Portrait; is defined in advance and includes labels and graphics. Let’s look at the final layout and the original template side by side.


Final Map and Layout Template

16. The one on the left is the map you will get and the one on the right is the template used to build it. First of all the large box towards the top of the template tells EngageBatchPrinting where the map should go. There is another one towards the centre bottom that defines the scale bar location.

17. Then there are reserved words on the template that are replaced when the map is generated. These words are MapTitle, CurrentDate, MapScale. Let’s look closer and see how these are handled.

Reserved Words used on Layout Templates


18. Here we can see that the template shows the word MapScale, however the final output displays Scale 1:12,078. Also the template displays CurrentDate however the final map displays 31/8/2010. These two words (MapScale and CurrentDate) are reserved words which when used on a MapShop template, are replaced at output time with the current values.

There are more reserved words you can use (e.g. MapTitle) which will be explained later. For now however, we can see that even though the person who designed the template didn't know the scale or print date of the map, this detail was automatically added at print time.

19. The remainder of the detail along the bottom of the map is purely there to enhance the map e.g. logo, legend, disclaimer notes. These were all added by the person who designed the original template.

20. Close all open layers in MapInfo Professional to complete exercise.

Step 4 – Printing a Key Map

Any catalogue of maps requires a section that shows the entire area covered by the Map Series, usually called the Key Map. To produce a Key Map in EngageBatchPrinting is as easy as turning on a few layers, picking a Map Series, and clicking the OK button.



22. Navigate to the Engage>EngageBatchPrinting>Open Map Series menu.

23. Open the CustMaps map series layer and select the Print Map Catalog>Print Key Map menu.

24. Populate the Setup Key Map Output dialog as seen in the image below.


Setup Key Map Output dialog

Make sure the following items are selected.

Do All Maps is ticked for the CustMaps Map Series.

The Key Title is named Key Map.

Show Map Name is ticked, and Show Map Number is deselected.

View/Edit layout before printing the Plot option is selected.

25. Click OK to generate the layout. On the Map Output toolbar, select the Print button to print this layout. Press the Stop button when printing has completed to close the layout window and return to the source data map window.

Set the Feature Layer as Secondary Roads, with the Feature Name as Street.

Set the Locality Layer as Census, with the Locality Name as Name.

Note The Locality layer is designed for polygons representing suburbs/states/council or political boundaries/provinces. Features will therefore be identified with this secondary attribute, allowing differentiation of features with the same name in different localities. However a Locality Layer is not compulsory.

Set the Map Layer as CustMaps, with the Map Name as Name.

Disable the Map Number option.

Select the Build index for only the selected maps in the series option.


31. Click OK and specify a name for the output index file (it is recommend storing these in a specified Index folder with explicit names to help later identification).

Step 6 – Print a Map Index

32. Open the EngageBatchPrinting>Print Map Catalog>Print Map Index menu option, and browse to and open the Index file created in the previous step.

33. Populate the Setup Map Index Output dialog as displayed in the image below.

4 Register Raster Image Tutorial 39

4 Register Raster Image Tutorial The objective of this tutorial is to register a raster image. If a raster image is opened into MapInfo Professional using File>Open, the image is displayed in non-earth coordinates. This means you cannot overlay vector data captured in a real world coordinate system such as latitude/longitude or UTM coordinates. To display a raster image such as an aerial photograph or scanned map the image must be “registered” i.e. assigned a real world coordinate system, so it can be displayed in the correct geographical location.

The Engage>EngageImages>Rectify Image tool is a powerful utility that enables the registration of raster images in geographic real-world coordinates. Unlike image registration using MapInfo Professional, the Engage Rectify Image tool can register and modify images that have been stretched, skewed or rotated. This process, known as rectification or “rubber-sheeting”, enables portions of an image to be stretched or warped to fit the entered control points.

Geo-register Image

Step 1 – Rectify using Ground Control Points (GCP) table

1. Select the Engage>EngageImages Menu. A new EngageImages menu is added to the MapInfo Professional menu display. Select Rectify Image.

Rectify Image dialog


2. Click on the Load an image file button and browse to the

\Engage3D_Tutorials\Register Image folder and select the PORT_TALBOT_IMAGE.JPG file.

3. When the Loading Control Points dialog appears click Yes.

Load control points

The PORT_TALBOT_IMAGE file will display in the Current Image map window along with a layer displaying four control points, one in each corner.

Note If the image does not display, right click the PORT_TALBOT_IMAGE layer in the ELC, and choose Display from the menu list. When the Display dialog box appears uncheck the Display within Zoom Range button or increase the maximum zoom.


ELC Display Options dialog

4. Under Control Points select the Open button and navigate to the folder \Engage3D_Tutorials\Register Image and open PORT_TALBOT_IMAGE_GCP.TAB. The Load Control Dialog box will open; specify the columns as shown in the image below.


Load Control Point dialog

If the message about Loading Control Points appears, select YES, this will overwrite the previously loaded control points.

5. Click Rectify and save with the default _rectified name extension. The rectified image will now open in a new map window. Finish by closing all tables.

Step 2 - Rectify Image without control points

6. From the EngageImages menu select the Rectify Image option.

7. Click on the Load an image file button and browse to the

\Engage3D_Tutorials\Register Image folder and select the PORT_TALBOT_IMAGE.JPG file. (You will be prompted that this file already exits. Click Yes to overwrite it). When the Loading Control Points dialog appears click NO.

8. Click on the Projection… button and change the projection to British

Co-ordinate Systems>British National Grid (EPSG:27700)


Choose Projection dialog

9. Add a number of control points to the image based on known real world coordinates. If there is no coordinate information available on the image then coordinate information can be extracted from vector data open in a map window such as road intersections, drainage convergence points, fence lines or property boundaries etc.

Hint Ideally, control points should be placed throughout the entire image and the more control points (providing they are accurately placed) the better the final rectification.

10. Open the table BUILDINGS into a new map window. This layer will be used to transfer control points to rectify the image. Tile the map windows to enable both tables to be visible.


Map windows tiled to rectify unregistered image

Click on the PORT_TALBOT_IMAGE map window and zoom to the top left hand corner of the image. Zoom to the same area in the BUILDINGS layer within the second map window. Press S on the keyboard to activate the Snap to node function. The word SNAP will appear in the bottom menu bar and a set of crosshairs will appear when the cursor is snapped to a node in the map window.

11. To add a control point, click the New Point button. A new record is added in the Ground Control Points window. Click on the Right Arrow icon to select the record.

Add new ground control point

12. With the control point record selected, click on the Image button and move the cursor to the map window containing the image to rectify. The cursor is now displayed as a set of crosshairs. Select the control point location using the corner of the large building in the image. The location of the X and Y pixel coordinates in the image are automatically updated in the control point Image_X and Image_Y cells.


Ground control point selected on unregistered image

13. To remove control points use the Delete Point button. The last change applied to a control point row can be reversed using the Undo Change button.

14. To add a the corresponding control point using the BUILDINGS Layer, click the Map button in the Rectify Image dialog box and then click on the same location in the map window using the Snap crosshairs as a guide. The Map_X and Map_Y co-ordinates are then automatically updated in the Rectify Image dialog box.

15. Follow the above procedure to add the remaining control points. Coordinates can be added manually to the Map_X and Map_Y boxes if known.


Manual control point editing.

16. If you need to modify the location of the control point on the image,

make the _ImageControlPoints layer editable in the map window, drag the control point to the new location using the cursor and then click the Sync Map>GCP button. The control point Image_X and Image_Y will be updated with the new pixel coordinate.

17. When all control points have been entered under Control Points click

the Save button and name the file PORT_TALBOT_IMAGE_GCP. If prompted overwrite the existing control point file. Click Rectify, a Save As dialog will prompt for an output file name and location. Overwrite any existing files if necessary and the rectified image will now be viewed in the map window. The registered image can be used to digitize various map objects such buildings, roads, bridges and open space. Close all open tables to complete rectification.

Engage contains a number of additional tools for working with images. These can all be found on the Engage Images menu and include the following:

• Reproject Image Reproject raster images into a new coordinate system.

• Image Properties View image projection, X and Y coordinate extents, number of rows and columns, total pixels, image type and metadata.

• Enhance Image Adjust image contrast and brightness and modify colour and gamma Red, Green, Blue channels.

• Filter Image Apply smoothing and edge detection filters to image.

• Clip Image Clip a raster image to a region.

• Rotate Image Rotate image by specified angle.

• Convert Image Save an existing image in a new image file format.


Step 3 – Enhance an image

This tool allows you improve the colour balance, gamma, brightness and contrast of an image without having to use third party software.

18. Open PORT_TALBOT_IMAGE_RECTIFIED and navigate to EngageImages>Enhance Image. Load the PORT_TALBOT_IMAGE_RECTIFIED in the Select Image drop down menu. Set the properties in this window as shown below to convert the image to greyscale and adjust the contrast and brightness.

21. Select a segment of the Pie chart. You will notice that it checks the appropriate column in the browser window and also selects the area in the Map above that it is spatially relevant to.

22. Click File menu and navigate to Save Data As>MapInfo Table, name the table Pop_25to34. This data will now be able to be opened in a browser window in MapInfo Professional. Close the table to finish.


Step 5 – Create Ternary plot

This step shows you how to use GraphMap to create a ternary plot and as with the previous step, you will save the graph for future use.

23. For this exercise open OA_CENSUS_SAMPLE from \Engage3D_Tutorials\Analytics folder.

24. Start GraphMap and select OA_CENSUS_SAMPLE table. Select the Create tab and then click on HEALTHG_01 (Good Health) in the data window. Press the keyboard key X to assign as the X-axis. Do the same for HEALTHF_01 (Fairly Good Health) and HEALTHN_01 (Poor health) and assign the Y and Z respectively. Now select Ternary as the graph type.

25. Select the Current Graph tab and select the Properties button, on the

right hand side of the screen. Under General select the Data Colour and set it to Lime; under Selection set Selection Colour as Red; under Scaling set Scale X, Scale Y and Scale Z to 1.5. Notice the scaling changing the appearance of your plot results.

26. Now select the Select Region tool and draw around a selection of

points on the graph. Notice that they change to the red colour selected previously. Under the Layers dockbar on the right hand side of the screen make sure that Graph Area, X Axis and Y Axis are checked as the below image shows.

27. Make sure that under the Legend tab the Size tab is selected and changed to Size 4. This will make the point objects larger.

28. On the Current Graph tab check Graph Titles to add a title to the top of your Ternary Plot. Check Object Info to show the points attributes when you hold the mouse pointer over it.


Ternary graph showing the relationship between good, fairly good and poor health over the Census area

You can use this Ternary Plot with the Map of the OE_CENSUS_SAMPLE data and aerial imagery to draw conclusions about location of housing and health. For example in the image below you can see that there is a dominant trend of fairly good to poor health in the North Western Area of the image. This is a small cluster in amongst an area of predominantly good health. Other census data such as Salary/Age etc can be added to link possible causes to this cluster.


The selection of points shows the trend between fairy good and poor health in the North West region of the census area

29. Go to the File menu and select Save Data As>MapInfo Table to save the graph as TERNARYPLOT and also as Comma Separated Values in the \Engage3D_Tutorials\Analytics folder. This ensures that the graph can be used later and the graph data can be imported in to various third party software. Finish this exercise by closing the table and Exiting GraphMap.

Step 6 – Compute Summary Statistics

The Summary Statistics tool reports a number of common statistical measurements for MapInfo Professional datasets. An optional group can be specified allowing statistics to be calculated for each distinct value in a group.

30. From within MapInfo Professional open the table SAMPLE AREA

WIND SPEED10M from \Engage3D_Tutorials\Analytics folder and view in a browser window by clicking on the button in the standard toolbar. Add the background image PORT_TALBOT_RGB_50CM. The wind speed table contains values for wind speed across the Port Talbot area. Each point in this dataset has a wind speed value for the Kilometre Sq around that point in m/s.

31. Open EngageAnalytics>Compute Summary Statistics fill in the Statistics dialog as the below image shows.


EngageAnalytics can generate a number of commonly used statistics and output these to a new browser window

Make sure the Data Handling Options are modified accordingly. See the image below.

Data Handling Options dialog


32. Save the Output table as WINDSPEED_STATS. A new browser window will open displaying the statistics for the wind speed over the Port Talbot area.

33. To demonstrate Summary Statistics that are grouped by a certain data field, open Table ROAD_TRAFFIC_ACCIDENTS from \Engage3D_Tutorials\Analytics folder.

34. Next select EngageAnalytics>Compute Summary Statistics and fill in the Select Statistics as shown in the image below. This time a group is added so that all Vehicle Types involved in accidents that resulted in Severe Injuries will be viewed along with the Min, Max and Total number of severe injuries recorded in each type of Vehicle. Fill in the Select Statistics as below; ensure that the Group Vehicle_Type is selected from the Select Group Field and that only Severe is selected in the Select Fields table.

An optional group can be used to calculate distinct values in a group, in the case Vehicle Type

35. Save the Output Table as ACCIDENTS_STATS. Close all open tables.


Browser Window showing statistics for each vehicle type

Step 7 – Trivariate Point Classification

Point classification of data is used to identify homogeneous groups of data within a sample population which can be distinguished from other groups. Samples that contain similar values for three specific variables are displayed using the same symbol style, colour and size to enable them to be easily viewed in the map window. For each variable or RGB channel a threshold value is entered and during processing each sample is assessed according to how its values compare with the threshold values set.

Point classifications can be displayed as a thematic map overlay or the new point symbols can be saved to the existing table or new table. Classification legends can be displayed as a thematic legend or as a MapInfo Professional table which can be edited and scaled. Each sample is assigned a point classification code which is saved to a new column in the original or new table.

This exercise will highlight areas of air pollution that have been consistently above the recommended NO2 air quality threshold (the values used are theoretical) over the years 2004 and 2005. It will then highlight the anticipated areas of improvement by 2010 with more effective air pollution constraints in effect.

36. Open PORT_TALBOT_RGB_50cm and AIR_QUALITY_NO2 from \Engage3D_Tutorials\Analytics folder.

37. Go to EngageAnalytics>Trivariate Point Classification. Enter the parameters as in the image below. The levels of NO2 in the Port Talbot area over 2004, 2005 and the predicted level for 2010 are going to be thresholded so that the areas that are above 17ppb NO2 are highlighted. Using the thematic legend, any improvement area will be highlighted. Select OK to run the point classification.


Point Classification menu where data variables can be selected. In this case the three channels are NO2 samples over three individual years.

38. The map below shows the result of the classification. The Red outlined dots show areas that have pollution levels above the 17 ppb recommended threshold. The Yellow dots show areas that had a threshold above 17 ppb during both 2004 and 2005, however in 2010 this will have dropped below the threshold value. This map now shows the areas of predicted improved air quality. Close all tables.


The yellow points show the areas where N02 will drop below 17ppb by 2010, highlighting the predicted improvement in air quality.

6 Engage ColourMap Tutorial 71

6 Engage ColourMap Tutorial The ColourMap module provides an efficient method of colourising polygonal maps from colour tables and thematic maps. ColourMap permanently colourises and saves the colour scheme to a MapInfo Professional table.

This exercise will show how a thematic map can be used to map objects permanently.

Step 1 – Create ColourMap

1. Open the WARDSWALES_COLOURMAP table from the \Engage3D_Tutorials\ColourMap folder into a map window and browser window view. Observe the fields in the table which are available to colour the Ward polygons.

2. Create an Individual thematic map by navigating to Map>Create Thematic Map with a Type Individual using the Region IndValue Qualitative Pastel template and the Code field.

The regolith polygons will be coloured permanently in the table using the colour scheme from the WARDWALES_COLOURMAP_LUT colour table.

6 Engage ColourMap Tutorial 73

Apply ColourMap dialog

Note It is possible to display the WALES_WARDS group colours using a thematic map layer as opposed to permanently colouring the map object polygons. To do this leave the Quick Colour using thematic map shading box checked. Experiment creating a blank look up table and colourising from an existing map. Close all tables.

Step 3 – Edit colour table

9. Once the colour table has been created or already exists in the correct format (with RGB values specified for each map code), you can choose the ColourMap>Edit Colour Table menu option for easy editing of individual colour assignments. Selecting this menu option brings up a list of the various codes and style pickers. When you have altered a style, click on the OK button to write the change to the colour table. If you have more global changes to make to the colour table, such as altering the patterns for a number of codes, this is best done with the Browser window and using the select/query menu commands.

33. Click the Compute button, and specify the output grid as RESERVOIR_CAPACITY. The computation results in a grid which contains values of the difference between the flooded dam surface at 125m and the ground level of the dam. Click Compute to generate the grid.

34. To calculate the volume of water the reservoir would hold at full capacity choose the EngageSurfaces>Grid Utilities>Volume menu option and select the grid RESERVOIR_CAPACITY. Select the action to Compute volume of main grid below constant Z value. Specify 125 as the Z value level to calculate the volume from as the proposed reservoir will be


filled to the 125m contour, and then click the Update button. The resulting volume is displayed in the Computed Volume box. The value is based on the grid Z-scale (thickness) value multiplied by the grid cell dimensions which are in metres, to produce a final volume in cubic metres.

Computation of the grid volume using selected criteria

The volume of water in the proposed reservoir can be calculated at different levels by altering the elevation level in the Z Value option.

Complete exercise by closing all tables.


8 Engage Create 3D Surface Tutorial This tutorial introduces the numerous techniques used to view surfaces in the 3D environment along with draping layers over topographic surfaces. The Engage3D window is a specialist application window similar to the MapInfo Professional Layout window which enables MapInfo Professional tables to be view in 3D.

Step 1 – Open surface

1. Open the PORT_DTM_SURFER table from the \Engage3D_Tutorials\3D Surface folder into a map window.

Step 2 – Display map in 3D

When a map is transferred from MapInfo Professional into a 3D display, the map needs to be ‘draped’ over a surface in the 3D Window. This surface is generally a undulating topographic or elevation surface such as a DTM.

2. Place the mouse cursor inside the map window and click the right mouse button. From the pop-up menu select the View in 3D. An alternative method uses the Engage3D>View Map in 3D menu option.


View surface in 3D menu

3. The View Map in 3D dialog provides you with the option to drape the map on a surface of Constant value (flat) or drape using a Grid file. Select the grid surface PORT_DTM_SURFER.


View map in 3D dialog

Display of the topographic surface in the Engage3D window

Step 3 – Display surface in 3D

4. With the PORT_DTM_SURFER map window active, select the Engage3D>View Surface in 3D menu option. This allows the selection of individual surface layers to be imported into the 3D Window.


The View Surface in 3D dialog only allows selection of surfaces

5. When the surface to import is selected click OK. A new surface branch is added to both the ELC, and the Workspace Tree. Leave the surface open in the 3D Window to use in the following navigation exercise. Close all layers in Engage3D after completion of Step 4 by navigating to File>Close All.

Note When tables are closed in MapInfo Professional, they are not automatically closed in the Engage3D window. Engage3D operates independently of MapInfo Professional although MapInfo Professional can be used to control which data tables and images are displayed in Engage3D.

Step 4 – Navigate within the 3D Window

The Engage3D Window is divided into three main sections:

• Toolbar buttons

• 3D display window

• Workspace Tree


Engage3D map window

The Zoom Controls toolbar contains navigation and 3D position options. These navigation controls are detailed below.

Zoom Controls toolbar

The Select/Navigate button is used to make windows active, control the 3D Cursor plane crosshairs, select or edit objects and list items. This is the default option for normal viewing and display modes.

Control of the 3D view is based on the cursor location. The 3D display spins around a horizontal axis if the cursor is moved vertically (with the left mouse button depressed), or in a circular movement around an axis into the screen when the cursor is moved horizontally.

The 3D Navigation button is used to provide greater control of 3D display manipulation. Sensitivity and speed of movement is controlled by the cursor’s distance from the centre point of the 3D window (the ‘view point’).


After clicking the 3D Navigation button move the cursor to the 3D display window (or click the right button while the cursor is located in the display and select Navigate 3D).

The 3D control sequences are:

• Left mouse button depressed with vertical movement rotates the image about a horizontal axis running through the view point.

• Left button depressed with horizontal movement rotates the image about a vertical axis.

• Right mouse button with vertical movement zooms the image in or out of the display. The numeric keys (1-0) can be used to control the zoom speed, with 1 and 2 applying the slowest zoom speeds and 9 and 0 the fastest.

• Left and Right buttons depressed with cursor movement allows positioning of the view point in the X/Y plane. Moving the cursor horizontally pans the view (moving the view point left/right), whilst moving the cursor vertically moves the view point in a ‘fly-through’ operation.

Keyboard entries with mouse manipulation can also be used to control 3D display operation. Available combinations include:

• SHIFT key plus pressed left mouse button repositions the view point in the vertical axis and screen plane (this only operates in Navigate 3D mode). Holding the cursor near the view point reduces the speed of panning.

• CTRL key plus pressed left mouse button repositions/rotates the image view whilst maintaining the current eye position. Nearer the centre of the view reduces the speed of panning.

Reset View restores the 3D display to a default such that the first displayed object is centred and shown within the window.

The Page Layout buttons are designed for use within the Page Layout view. The Zoom In and Zoom Out controls allow adjustment of the overall zoom ratio of the page display, whilst the Pan button enables you to position the cursor in a display window and roam the view.

The Fit to Page button is only available in Page Layout view, and automatically resizes the page to fit to the extents of the view.


Close any open tables in the 3D window and MapInfo Professional after exploring 3D navigation.

Note: If you have a mouse with an ‘active’ wheel, you can also use this for zoom operations. This is only recommended for use in controlling the Page Layout View, not 3D View.

Note When using either Zoom In or Zoom Out options holding down the SHIFT key invokes an opposite zoom command. For example, if you zoom in and hold down the SHIFT key, the cursor changes to the zoom out cursor.

Step 5 – Drape map window over surface grid

Within the Engage3D window it is possible to drape another dataset (e.g. an aerial photograph or satellite image) over a terrain surface.

6. Open the PORT_DTM_SURFER and PORT_TALBOT_RGB_50CM tables from the \Engage3D_Tutorials\3D Surface folder into a map window. Order the layers so the aerial photograph is positioned above the grid surface.

7. To drape the aerial photograph over the topographic surface navigate to the Engage3D>View Map in 3D menu option. Select the grid surface PORT_DTM_SURFER to drape the aerial image over.


Aerial image draped onto the topographic surface

Step 6 – Control image display properties

The Properties dialog of any branch in the Workspace Tree can be displayed by positioning the cursor over the object branch and right clicking the mouse button. Attributes such as colour, transparency, position or data controls are some of the items which can be customised.


Accessing the Image Properties from the Workspace Tree

8. From the Images branch select the Properties menu option. Navigate to the Transparency tab. Experiment with the image transparency by sliding the bar to the right or by setting a percentage transparent value (e.g. 0% has no transparency, 100% has full transparency). Click the Apply button to initiate a transparency modification.

Step 7 – Modify vertical scale of 3D surface

9. Open the 3D Map Properties dialog for the current 3D window. Navigate to the Scale tab. The slider associated with the Z Scale controls the vertical exaggeration. Apply a vertical exaggeration of 1.8. The vertical exaggeration improves the three dimensional perception of the view.


3D Map Properties dialog controlling the vertical exaggeration

Note: In most cases, when using the properties dialogs for modifying display controls, you will need to click the Apply button before the current view is refreshed. On certain dialogs an Auto Apply option is available that allows the screen view to update as changes are performed.

Step 8 – Add surface layer from MapInfo Professional into 3D

10. Open the WINDSPEED_10M table from the \Engage3D_Tutorials\3D Surface folder. Select the Engage3D>View Surface in 3D menu item. When prompted select the WINDSPEED_10M dataset and click OK.

11. Close newly created surface branch in the Workspace Tree.


Specifying a surface to display in Engage 3D

Display the Surface Properties dialog (double-click on the Surface branch). The Surface Properties dialog is divided into the following sections:

• Image and surface tree – Used to add and modify images, surfaces and contours.

• Data selection and control – The data selection and control area offers image processing control such as transparency, offset and scaling.

• Preview window – The preview window is used to ensure an enhancement of data selection is correct prior to displaying in the main Engage3D window.

Surface Properties dialog


Step 9 – Add surface layer directly in 3D

12. To add data directly into the 3D environment create a new Surface

branch by navigating in the 3D window menus to Display>Surface. Display the Surface Properties dialog for the new layer, and click the Load New Grid button. From the Open file dialog, navigate to the \Engage3D_Tutorials\3D Surface folder and select WINDSPEED_10M file.

Note The WINDSPEED_10M surface is derived from dataset of estimated windspeed across the UK, based on a 1km grid a height of 10m above the ground level. The estimates are based on the results of an air flow model that measures the effect of topography on wind speed. There is no compensation for the effect of local thermally driven winds such as sea breezes or mountain/valley breezes.

13. The new surface is displayed at the same level as the existing satellite raster image. To add an offset select the Surface branch of the image and surface tree. Add a Scale factor of 100 and an Offset of 300, click Apply.

Offset and scale surface from image


Note Vertical scaling can be applied to each surface independently using the scale control of the Surface branch. A vertical scale factor for all surfaces can be applied by using the 3D Map branch Scale tab (see Step 7).

Vertical scaling of an Image that is draped over a surface in Engage3D can altered by setting a Z scaling factor under the Transform tab for the Image properties..

Vector files derived from the Extrusion Wizard provide a flexible and powerful method of displaying two dimensional data in Engage3D. The following steps provide an example of displaying the same data in 3D displays as solids and strip contours.

14. Open the MOTORWAYNOISE_POLYLINES table in MapInfo Professional from the \Engage3D_Tutorials\3D Display folder.

Note The MOTORWAYNOISE_POLYLINES table represents noise levels in dB(A) as polyline contour objects.

15. Select the Engage3D>3D Extrusion Wizard menu option and highlight the MOTORWAYNOISE_POLYLINES table. Click OK to proceed.

Select data to extrude

16. Click Next at the base of the dialog to progress through the wizard. The second and third screens are used to define the vertical positioning of the bottom and top surfaces respectively. For the base of the MOTORWAYNOISE_POLYLINES or Primary Z, check the Plus field value option and specify the NoiseLden_decibels field. Uncheck the box Generate primary surface. For the upper surface or Extruded Z, check


the Plus field value option selecting the NoiseLden_decibels field, and extrude with value of 200. Set the Extruded Z to be relative to the primary Z value.

17. Within the fourth and fifth wizard dialogs azimuth, dip and grid compression factor can be applied; leave all defaults.

18. The appearance of the noise polylines can be controlled in the sixth wizard dialog. Select the option Cycle through standard DXF colours and make sure the Generate sides option is checked.

19. The seventh wizard controls the output vectors created as a DXF file or Feature Database. Select File output, and by default, it will use the input data table name. Click Next.

20. The final wizard dialog displays the output .DXF layer controls. Leave the Default Layer output.

When you click either the Finish or Apply buttons, the Engage3D window updates to show the created and extruded polylines.

Step 6 – Extrude polygons into Engage3D

As the data objects are regions in this case, the Extrusion Wizard can be used to ‘fill’ the area between the contours.

21. Open the MOTORWAYNOISE table in MapInfo Professional from the \Engage3D_Tutorials\3D Display folder.

Note The MOTORWAYNOISE table represents noise levels dB(A) as polygon region data objects.

22. Select the Engage3D>3D Extrusion Wizard menu option and highlight the MOTORWAYNOISE table. Click OK to proceed.

23. Click Next at the base of the dialog to progress through the wizard. The second and third screens are used to define the vertical positioning of the bottom and top surfaces respectively. For the base of the MOTORWAYNOISE or Primary Z, check the Plus field value option and specify the NoiseLden_decibels field. Check the box Generate primary surface. For the upper surface or Extruded Z, check the Plus field value option selecting the NoiseLden_decibels field, and extrude with value of 200. Set the Extruded Z to be relative to the primary Z value. Check the box Generate primary surface.

24. Within the fourth and fifth wizard dialogs azimuth, dip and grid compression factor can be applied; leave all defaults.

25. The appearance of the noise polylines can be controlled in the sixth wizard dialog. Select the option Cycle through standard DXF colours and make sure the Generate sides option is checked.

26. The seventh wizard controls the output vectors created as a DXF file or Feature Database. Select File output, and by default, it will use the input data table name. Click Next.

27. When you click either the Finish or Apply buttons, the Engage3D window updates to show the created and extruded polygons. Open the Vectors Properties dialog and ensure that Transparency option is enabled to 50% transparency.
