GMTSAR

Enter boundary coordinates and hit generate to run the DEM generate script. The boundary cannot span more than 6 longitude by 4 latitude degrees. Three land data bases are available:

SRTM1 - global but only extends to latitudes of +/-60 degrees, 30 m resolution
SRTM3 - global but only extends to latitudes of +/-60 degrees, 90 m resolution.
ASTER1 - global but lower quality, 30 m resolution.
(Note the SRTM data has been updated to V3 http://www2.jpl.nasa.gov/srtm/).

This site is very slow. Please try the local GMTSAR command:
make_dem.csh W E S N [mode]
mode 1:SRTM-1s 2:SRTM-3s

"Check Status" to check the status of the query and retrieve any produced files at a later time using the ID (copy number below before moving to next page) or just wait.
