TopoFusion Pro / DEM accuracy in Africa?
« on: April 02, 2016, 10:07:21 AM »
Hi
How accurate is the DEM data that Topofusion uses when I click "Correct Elevation using DEM"? What is the source?
I have a trail run track in Cape Town, South Africa and from what I can figure out, the most accurate free DEM data for Africa is the SRTM1 30m data that can be downloaded from the USGS website.
Is this a similar sort of elevation accuracy that the same track would get from some websites that use the Google elevation api to source DEM data?
Thanks!
Alistair
