It is best to use a browser with WebGL support such as the latest versions of Google Chrome, Mozilla Firefox and Internet Explorer (IE) 11. It will also work in some older browsers (for example IE9 and IE10) but the map rendering will be limited. It may not support 3D rendering of maps, so the 3D Terrain option may show the same result as 3D Smooth.
There are three types of spatial data which are read from the data sources and displayed by DE Africa Map over its base maps:
Point Click on any point to see more information about that particular point feature.
Line Click on any line to see more information about that particular line feature.
Region Click within any region to see more information about that region.
Some older computers do not have graphics cards which fully support WebGL and some older browsers do not make use of this support even if it is present. The DE Africa Map requires this support in order to support 3D Terrain Perspective View.
Try upgrading your browser to the latest version. If that still does not work, you may need to consider working on a computer that has more recent graphics support.
DE Africa Map automatically changes the content of the map according to the scale at which you're viewing. If you zoom in it shows more detail. At some points in the zoom range, the map display switches from high altitude photography to lower altitude photography. These sets of the photography are not colour matched to each other, so may have quite different hues. The actual photography scales used, the date of that photography and its lighting conditions will vary across Australia.
When you are using Perspective View the part of the terrain nearest to the "camera position" is naturally shown at a larger scale than the more distant parts. Depending on your zoom level, this can result in the foreground being displayed with a different set of photography from the distant parts of your Perspective View.

The spatial data displayed by the DE Africa Map is sourced from a range of organisations.
You can see details of the department or agency that provides the spatial data by clicking About this data in the data workbench.
The spatial data displayed by the DE Africa Map are referenced directly from the supplying department or agency by the DE Africa Map server. If that supplying department or agency updates or removes any data, that change will be reflected immediately by the DE Africa Map.
If you have any questions about the spatial data, you will need to contact the supplying department or agency.
The base maps displayed by the DE Africa Map come from a number of difference sources including Microsoft’s Bing, Geoscience Australia, Esri and NASA. They are downloaded from the source as they are required, so they are as up to date as that service provides.
The DE Africa Map was developed by Data61, working closely with Geoscience Australia. See the About page for more information.
Before distributing any data from DE Africa Map it is important to understand the licence restriction for the data. All data sets displayed by the DE Africa Map are the property of the department or agency which has provided them.
The licence which governs the usage and distribution restrictions for each data set is shown in catalogue.
The reliability will vary between data sets. To understand the reliability of a particular data set, click on the title of the data set in question in the Data Catalogue for more information. The metadata which is shown in the Data Catalogue may offer sufficient information or you may need to contact the listed data provider.
The DE Africa Map's spatial data does not cover the rest of the world.
