I am working on elevation data for an area in Sudan. Between Google Earth Pro and SRTM elevation data, which one is more reliable?

1 Answer 1


Both are the same.

Google Earth uses the SRTM elevation data according to this topic on the Google Earth Help Forum:

The global terrain dataset is 90M SRTM

It says the same thing on Wikipedia:

Google Earth uses digital elevation model (DEM) data collected by NASA's Shuttle Radar Topography Mission (SRTM).

    1 arc-second (~30m) SRTM is now available worldwide. I don't know if Google is using it yet.

  • I suspect Google will be using the void-filled SRTM (SRTM Plus), rather than the original SRTM, although this is more an issue in mountainous areas. If OP uses the original, would need to fill any voids themselves.

  • I am finding some differences (1-2 meters) between the two datasets, I am almost sure the I did the georeferencing well

  • I am using the 30 arcsec database, non Void-filled
