GMTSAR

Enter boundary coordinates and hit generate to run the DEM generate script. The boundary cannot span more than 4 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 process is slow (10 minutes) so please be patient. When it is done hit "Download" below.

"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.
