Terrain Data Sources

 Data available through Pathloss 6 automatic download

Global Terrain Data Sources

SRTM 1" 

Global 1" DSM between 60 degrees north and 60 degrees south. Pathloss 6 can automatically download and configure SRTM terrain data.

https://www2.jpl.nasa.gov/srtm/

This data is normally used as a clutter source, but can be used as terrain data.

ASTER 1" 

Pathloss 6 can automatically download and configure ASTER terrain data. Downloading 1" ASTER data requires a NASA Earthdata Login username and password. To obtain a NASA Earthdata Login account, please visit:
