DEM for South East Asia

Recommended Posts


I am searching for DEM source for south east asia (Vietnam, Laos, Cambodia).  Problem is that I need a better accuracy than 1 arc/sec, so SRTM / Aster is a nogo.  This is for a non commercial simulation project.

It would be great if someone could someone point me to a good source.

the best bet if you find free data programs, you submit a research and get the data, I saw once Tandem-X offer this programs.

for now, a completely free DEM data stuck in 30 m resolution, 

anyone have another update maybe?

hey tandem-x have a general proposal programs, maybe you can try it :
