Africa height data

Recommended Posts

Hey,

 

Depends what fidelity you looking for.

 

For DEM you could always try:

 

ASTER: http://asterweb.jpl.nasa.gov/gdem.asp

 

mad mappers: http://www.madmappers.com/

 

Then if you are looking for more detail you can buy data directly from the National Geospacial Information agencies in each country you looking for.

For instance: http://www.ngi.gov.za/index.php/what-we-do

Its dirt cheap, but may take a little time.

 

The nice thing about DEM data is that you can use it for heightmaps, or use a free utility like http://www.qgis.co.za/en/site/ to extract the contours as splines ( which can then be imported into whatever 3D package you want )

 

Just remember that the DEM data uses floating point, so if you download an image and it looks black don't worry. If you crank the levels you'll start seeing the information.
