Greater Wellington Regional Council - Public Web Map Application
Overview
This application is a web mapping application for use by anyone who wishes to view map information for the Wellington Region. For example, you can
search for addresses or resource consents, assess natural hazards in your area, look at outdoor opportunities in the regional parks, or review natural
resource plans which affect the region.
Greater Wellington Regional Council promotes Quality for Life by ensuring our environment is protected while meeting the economic, cultural and social
needs of the community. Our specific responsibilities include environment management, flood protection and land management, provision of regional
parks, public transport planning and funding, and metropolitan water supply.
The maps consist of a basemap (e.g. aerial photos) overlain by a set of overlay layers. Map overlays are grouped by theme, and a switcher button
allows you to move between collections of themes. The application is usually accessed from the Map Gallery page (URL http://mapping.gw.govt.nz/gwrc/)
The application is compatible with all modern web browsers including browsers on mobile devices.

Layer Tools
Each layer can be expanded in the Layer list to provide more details.
Clicking on the “…” symbol next to a layer name in the Layer list will open a context menu, as shown below.
Click here to cause descriptive pop-ups to appear when
you click on a map feature in this layer
Open a view of the attribute table associated with this
layer
Open a new browser tab showing a description of the layer
Click here to expand the layer details to show sublayers
and symbology
A downward pointer indicates that the layer is fully
expanded.
Clicking in a tick box shows the layer on the map (as long
as the parent layer is also ticked).
Table View
Clicking on the Table View handle (centre bottom of map screen) or using the “Open Attribute Table” layer option shows the Table View, as below.
The Table View shows the records associated with each map layer. By default, the “Filter by Map Extent” option is turned on (so only features in the
current map extent appear as records in the Table View).
You can click on the box at the extreme left of a record to highlight or “select” it. This highlights the record(s) and associated map feature(s) in blue.
The “Zoom To” option will then zoom to the map extent for the selected feature.
Show only Selected Records in the Table View
Apply a filter (see below for dialog)
Show/Hide table columns
Export table data to CSV format (e.g. to use in Excel)
The Filter Dialog
Choose “Add a filter expression”
Then choose an attribute field name, then a query term,
e.g. locality is Waikanae Beach
This will filter layer data in the table and map views to only
show features matching the expression.
Tool details
Most tools may be reasonably self-explanatory, but further detail might be useful for 2 of the tools for changing map content, as below.
Choose – map content
This tool allows you to change the content of overlay themes in the map. For example, you may have started by opening the Consents and
Environmental Monitoring map, but now you want to look at Planning-related maps. Click on the Choose button, & click on the Regional Planning
icon. The map will refresh & redisplay the startup screen. The map will now show overlay themes for planning data.
Add data – from web
This tool allows you to add extra content layers to the map. Choose a tab for the type of content to add.
Search – choose one of the listed layers (or groups of layers) & click ADD. The layer(s) will be added to the map, and appear in the legend and layer
list tools. Click on the Layers link (bottom right) to view a list of layers you have added.
URL – enter a URL for a layer that you wish to add to the map. For example, try a wind zones layer supplied by Hutt City Council. The URL is
http://gisweb.huttcity.govt.nz/arcgis/rest/services/Online/Wind_Zones/MapServer.
File – drag and drop a zipped file, or browse for a file on your computer, to add as a layer to your map. For example, imagine you want to know
about lightning groundstrikes in the Wellington City area. You can source this data from MfE at their Data Service site :
https://data.mfe.govt.nz/layer/3558-lightning-groundstrikes-by-region/
Follow the URL link in your browser. Add this layer to the MfE Data Service map, set a crop area, and download, using default settings. This requires
a free registration to use the site. Save the downloaded zip file somewhere on your computer.
Return to the GWRC map site. Choose Add Data – File, click the Browse button, and locate the zip file & load it. Lightning strike points will appear in
your map as a new layer.
Copy and paste this URL text into the URL box on the tool, & click ADD. The layer is added to
the map (you may have to zoom in to make the layer visible).
You can also paste the URL text into the address bar of your browser. It will show an
information page describing the dataset.
Map Services
Clicking on the Layer “Description” option as in Layer Tools above shows a new browser page with details about the layer. The new page has a full
description of the web map service. The URL can be used to embed the map layers into other applications, e.g. ESRI ArcMap, or QGIS.
