3.1.2 GeoNode Portal

Geonode Introduction

What is GeoNode?

GeoNode is a geospatial content management system, a platform for the management and publication of geospatialdata. It brings together mature and stable open-source software projects under a consistent and easy-to-use interfaceallowing non-specialized users to share data and create interactive maps.

Data management tools built into GeoNode allow for integrated creation of data, metadata, and map visualizations.Each dataset in the system can be shared publicly or restricted to allow access to only specific users. Social featureslike user profiles and commenting and rating systems allow for the development of communities around each platformto facilitate the use, management, and quality control of the data the GeoNode instance contains.

It is also designed to be a flexible platform that software developers can extend, modify or integrate against to meetrequirements in their own applications.

A tour of GeoNode

In order to get started, let’s look at the GeoNode interface and get a feel on how to navigate around.

The GeoNode web interface is the primary method of interacting with GeoNode as a user. From this interface, onecan view and modify existing spatial layers and maps, as well as find information on other GeoNode users.



Without being logged in, you are limited to read-only access of public layers.

1. Navigate to you your GeoNode instance, available here:

Fig. 3.1: Welcome page

This page shows a variety of information about the current GeoNode instance. At the top of the page, a toolbarexists showing quick links to view layers, maps, documents (metadata), people ADD LINK, and a search field.Below this is a listing of recently updated layers, including abstract, owner, rating, and download button (ifavailable).

2. Click the Layers link in the toolbar to go to the Explore Layers page.

This page shows all layers known to GeoNode, available in either List or Grid viewing. Layers can be sortedby Most Recent, Most Popular, or Most Shared. Also available are a list of categories, with which layers can beconnected with.

3. Find a layer and click on its name.

4. A layer viewing page will display, with the layer itself superimposed on a hosted base layer (in this caseMapQuest OpenStreetMap). Explore this page, noting the various options available to you.

5. Now click the Maps link in the tool bar to go to the Explore Maps page.

This page shows all maps known to GeoNode, available with similar viewing options as with the layers.

6. Type San Andres in the Search Box at the top of the page and hit Enter.

This page contains a wealth of options for customizing a search for various information on this GeoNode in-stance. While a simple search box is available at the top of every page, this search from allows for much morefine-tuned searches.

Managing Layers

After user accounts, the next primary component of GeoNode is the layer. Layers are a published resource representinga raster or vector spatial data source. Layers also can be associated with metadata, ratings, and comments.

In this section, you will learn how to create a new layer by uploading a local data set, add layer info, change the styleof the layer, and share the results.

Uploading a layer

Now that we have taken a tour of GeoNode and viewed existing layers, the next step is to upload our own.

In your data pack is a directory called data. Inside that directory is a shapefile calledsan_andres_y_providencia_administrative.shp. This is a data set containing ... This will bethe first layer that we will upload to GeoNode.

1. Navigate to the GeoNode welcome page.

2. Click the Layers link on the top toolbar. This will bring up the Layers menu.

Sharing layers

GeoNode has the ability to restrict or allow other users to access a layer.

Anonymous access

1. Go to the layer preview of the first layer uploaded, and copy the URL to that preview page.

3.1. For Users 65


Fig. 3.35: New comment posted

Note: The URL should be something like: http://demo.geonode.org/layers/geonode%3Asan_andres_y_providencia_administrative

2. Now log out of GeoNode by clicking on your profile name and selecting Log out.

3. Now paste the URL copied about into your browser address bar and navigate to that location.

4. You should be redirected to the login page. This is because when this layer was first uploaded, we set the viewproperties to be any registered user. Once logged out, we are no logner a registered user and so are not able tosee or interact with the layer.

Sharing with other users

Adding more layers

We’ve uploaded one layer so far. There is one more layer in the data directory associated with this workshop calledsan_andres_y_providencia_poi.shp.

1. Upload this layer, referring to the directions on uploading a layer. As a difference, leave the permissions set totheir default values.

Managing Maps

The next primary component of GeoNode is the map. Maps are comprised of various layers and their styles. TheLayers can be either local, served by the local GeoServer or remote, served by other map service providers such asOpen Street Map, Google, Bing or MapQuest.

The GeoNode Map viewer provides tools for map navigation, layers management, ordering and styling, identifyingfeatures, etc.

In this section, we will create a map based on the layers uploaded in the previous section, combine them with someexisting layers and a remote web service layer, and then share the resulted map for public viewing.

2. Click the Create a New Map button to launch the map composition interface.

In this interface there is a toolbar, layer list, and map window. The map window contains the MapQuest Open-StreetMap layer by default. There are other service layers available here as well: Blue Marble, Bing Aerial WithLabels, MapQuest, and OpenStreetMap.

3. Click on the New Layers button and select Add Layers.

4. Select all of the San Andreas layers by clicking the top entry and Shift-clicking the bottom one. Click AddLayers to add them all to the map.

Note: This selection includes not only the two layers uploaded in the previous section, but also the layers thatwere already hosted on GeoNode at the beginning of the workshop.

5. The layers will be added to the map. Click Done (right next to Add Layers at the bottom) to return to the mainlayers list.

Saving the map

1. While we still have some work to do on our map, let’s save it so that we can come back to it later. Click on theMap button in the toolbar, and select Save Map.

2. Enter a title and abstract for your map.

This link contains a permalink to your map. If you open this link in a new window, your map will appear exactlyas it was saved.

Styling layers

In this interface, we can pause in our map creation and change the style of one of our uploaded layers. GeoNode allowsyou to edit layer styles graphically, without the need to resort to programming or requiring a technical background.

We’ll be editing the san_andres_y_providencia_poi layer.

1. In the layer list, uncheck all of the layers except the above, so that only this one is visible (not including the baselayer).

2. Zoom in closer using the toolbar or the mouse.

3. In the layer list, click to select the remaining layer and then click the palette icon (Layer Styles). This will bringup the style manager.

4. This layer has one style (named the same as the layer) and one rule in that style. Click the rule (Untitled 1) toselect it, and then click on Edit below it.

5. Edit the style. You can choose from simple shapes, add labels, and even adjust the look of the points based onattribute values and scale.

6. When done, click Save, then click on the word Layers to return to the layer list.

Share your map

Now let’s finish our map.

1. Check the box next to the highway layer to activate it. If it is not below the POI layer in the list, click and dragit down.

2. Make any final adjustments to the map composition as desired, including zoom and pan settings.

3. Click the Map button in the toolbar, and then click Publish Map.

4. The title and abstract as previously created should still be there. Make any adjustments as necessary, and clickSave.

5. A new dialog will appear with instructions on how to embed this map in a webpage, including a code snippet.You can adjust the parameters as necessary.

Your map can now be shared.
