AfricaTopo is a Mad project aimed at creating a 20m contour map of the African continent for use as a background map on a GPS. The project is well under way and the first step has now reached completion: South Africa.
The mapset includes 20m contour lines, elevation points, trig beacons, rivers, water areas and coastline. The set is compiled transparent so that it can be used in conjunction with other GPS maps e.g. overlaid on road maps on the GPS. More information can be found at
As a bonus we have included on the AfricaTopo CD the latest version (ver.1,32) of NASA World Wind free 3D interactive map of the Globe with the plug-in for your GPS.
We thank the Chief Directorate of Surveys & Mapping of South Africa for providing the data thus making this first step possible and all their staff, Sue and Raoul in particular, for being extremely patient and helpful. It is remarkable how much passion for GIS and mapmaking can be found at CD:SM, it is rare to meet someone who has fun at work!
