NR Maps Frequently Asked Questions

Natural Resource (NR) Maps is a web mapping tool to discover, research and map natural and cultural research data for the Northern Territory (NT).

Read below to find out how to use NR Maps.

You should also read the user guides on NR Maps information and find out about geospatial resources.

How to use the active layer

You can use the active layer to select features on the map screen.

Only one layer can be active.

You will find the active layer under the land administration folder.

If you want to select features on the map screen from another layer, you must change the active layer first.

Do this by using your right mouse and click on a layer. Select set active.

If a layer has search functions, they will be enabled when the layer is active.

How to select features

To select features on the map screen, you must be on the active layer.

In NR Maps, cadastre is the active layer.

Get information from data layers

Every data layer in NR Maps contains descriptive information in the metadata record.

Right click on any data layer and select metadata.

Metadata includes the following information:

  • the custodian
  • how and when the data was compiled
  • data dictionary.

Save your session

Save your session by using the bookmark tool. This will ensure you keep:

  • zoomed extent
  • display layers
  • the active layer
  • redline drawing markups.

You will find the bookmark in the list of tools at the top if the screen.

Hover the mouse over each tool to view a short description.

You can save, email or set the web ink as your favourite.

Export data

You must zoom in to a scale < 1:600,000 to activate the data export tool.

You can only export data layers if the Department of Environment and Natural Resources is the custodian.

To find out custodian details you can:

  • check the metadata record
  • hover the mouse over the layer folder name.

Get images from Google Earth

NR Maps is unable to display image dates for basemaps layer using Google Satellite.

Image dates are displayed using the free Google Earth Pro software.

Use the time-slider tool to verify latest imagery and display historical images.

Google Earth displays a mosaic of the best available images between one and three years old.

Google Earth images with cloud cover are not displayed.

Pre-set scales: numbering

Previous versions of NR Maps had a simpler set of pre-set scales eg 100k, 250k, 500k, 1000k.

When Google Maps and Google Satellite were added as basemap layers, the pre-set cached scales for these systems replaced the existing scales.

One click on the map screen represents a 50% zoom in or out.

Layer names

To search layers for key words follow these steps.

Step 1. Find the filter layer tool at the top of the layers panel.

Step 2. Enter a name in the filter text box eg water.

Step 3. Close the filter to return to the default listing.

All layers containing the search word will be filtered in a new list

Folder names are also included in the search.
