I'm working on a very quick project for a magazine and need shaded reilf images or data than I can qucikly get into Illustrator or MAPublisher of N. Algeria and N. India.

Any tips on where to go for the data?

How urgent is urgent and what area/resolution are you specifically looking for? Would NaturalEarth be acceptable?

If you have the DEM data (SRTM) you can get something out of Global Mapper that looks fairly decent within a reasonably short amount of time. For any project where I have some extra time, I always pick Visual Nature Studio.

urgent as in they need it by Friday. I got my hands of Algeria terrain data already processed to AI, so now all I need is a shadded relief image of India. I need a grey scale image so I can re-color it in photoshop.

I'll see what I can do with the Natural Earth images. For projects with more time I use Natural Scene Designer which looks to be very simialr to VNS. I'd be using it now except I can't get the data CD for Asia before the deadline.


Hold the phone, I just realized NSD can directly import DEMs, so all I need is a DEM of India! Off to look, but if you know of a really good internation elevation data clearighouse please let me know.

http://srtm.csi.cgiar.org/ offers 5 x 5 degree SRTM tiles which have been error-corrected. http://www.viewfinderpanoramas.org/ also offers terrain data, with a lot of manual corrections done to it, for certain regions.

Thanks Hans, I eventually found my way to the srtm data and it was just what I needed.

David - for the future - SRTM is probably overkill for the scales you are looking at, you could use a even lower resolution DEM - such as GLOBE, GTOPO30 or ETOPO5/ETOPO2.
