Get started

To launch DEA Map and display basic data:

  • Display the DEA Map by using the URL
  • In the left hand panel click the Add Data button to launch the data \catalogue.
  • Browse through the data catalogue to find a data set of interest.
  • Click on the title of your prefered data set to get a preview of that data, along with a description and other relevent metadata.
  • To view your selected data set on a larger map, click the Add to the Map button. The spatial data will be immediately displayed in the map view, and a visual legend for that data will appear in the Data Workbench, located on the left hand side of the page.
  • It may not be immediately obvious where your selected spatial data has loaded on the map if does not cover a large part of Australia. To locate loaded data on the map, go to the Data Workbench (positioned on the left hand side of the page), and click the Zoom to extent link for your desired data set. From here you can also click About this data to get more information about your selected data set.
  • To add additional data sets to the map, simply click Add Data again in the left hand panel to relaunch the Data Catalogue.
  • Zoom manually by moving your mouse pointer over the map and using your mouse wheel to zoom in or out further.
  • Click and drag the map to further show the region in which you are interested.
  • Click on a feature (that is, directly on a point or line, or within a region) to show data about the individual feature.

You can perform these steps in any order as required to tune your display of spatial data.

A displayed feature

Click on the feature which is displayed on the map. You can click on points, on lines or within regions to see a display of the information available from the spatial data provider for that particular feature.

For points and lines, you need to click quite accurately to identify the feature. For regions, clicking on the boundary will give ambiguous results. Click within the region.

Display your own spreadsheet or spatial data

DEA Maps can display two kinds of spreadsheets:

  1. Spreadsheets with a point location (latitude and longitude) for each row, expressed as two columns: lat and lon. These will be displayed as points (circles).
  2. Spreadsheets where each row refers to a region such as a local government area (council), state, postcode, or ABS statistical unit such as an SA2 or CED (Commonwealth Electoral Division). Columns must be named according to the CSV-geo-au standard. These will be displayed as regions, highlighting the actual shape of each area.

Spreadsheets must be saved as CSV (comma-separated values).

Other standard spatial data types such as GeoJSON and KML are also supported.

There are two ways to load your data:

  • Drag your data file onto the NationalMap map view. The format of the data file will be auto-detected.
  • Click on the Add Data button in the left hand panel. This will launch the Data Catalogue. Select the My Data tab at the top of the modal window and follow the provided instructions.

You can click on the regions or points to see the data available for that location. If the file is a CSV file, the data from all columns will be shown in the feature information dialogue when you click.

You can also use all of the features of the Data Workbench on the data you have loaded as well.

To share a view of your data with others, you must first publish it to the web somewhere with a URL, and then load it from there.

Share my DEA Map view with others

There are three ways:

  • Click the Share button, copy the given URL (shown in the first text box) to the clipboard and paste it into an email which you send to the recipient. They can click on it in the email or paste it into their browser to see the same view as you.
  • Click the Share button, copy the HTML fragment (shown in the second text box) and paste it into an HTML file, which you then make available to the recipients. When the recipients display your web page, they will see the DEA Maps view within that web page.
  • Take a screenshot and email it as an image (see your OS instructions on how to take a screenshot). This will share all information, even if loaded from a local file or URL.

Note that only the third method will show the data you have loaded from a local file.

Contribute datasets to DEA Maps

DEA Maps encourages data providers to publish their spatial data using this platform.

If you require your dataset to appear under a separate category of the DEA Maps Data Catalogue, contact the support for DEA Maps at You will need to provide an internet accessible service in a standard protocol to access your dataset on the internet and appropriate references must be added to the DEA Maps configuration.
