Thanks James

Hayder Dibs

Dear you can find many websites provide you with the DEM, but with resolution around 60 and 90m. However, if you want higher you can use GPS points then generate your DEM using arc gis

regards

Sumeet Chavhan

USGS EARTH EXPLORER WILL HELP.

@Hayder, thanks but i am using 30m of landsat-8 with Erdas and ENVI. I'll try the GPS points on ArcMap as suggested.

@Sumeet, thanks but my question stated "Aside downloading ASTER or SRTM DEM" which can be gotten from EarthExplorer.

what about TOPOSHEET?
