Aster GDEM

[Nguyen Ngoc Tue]

Dear SWAT-Users,

I downloaded Aster GDEM data (30m) from http://www.gdem.aster.ersdac.or.jp/search.jsp already but I do not know how to creat DEM map in ArcGIS 9.3. Could you tell me the way to do that as soon as possible?

Thank you very much for your cooperation.

Best regards,
Micno

Hi Tue,

In ArcGIS 9.3, you can create DEM map by using 3D analyst tool. The
process includes 3 steps:
- From topographic map, create contour map (vector)
- From contour map, create TIN
- Convert TIN to raster (DEM)

Cheer,
