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