I wish to extract elevation data from geotagged photos?
I have worked with DEM's and the open source CLI program: GMT for my graduate studies. I own a DJI Phantom 3 and used the trial version of Drone Deploy.
They are able to take geotagged jpg photos and create elevation data from it but how is this possible?
In the trial version they do not allow direct download of raw elevation data, but they do supply a Geotiff of the survey area, and using GMT I can convert the geotiff to netCDF file where then I can plot it again. However the elevation data isn't accurate as it would be on the DroneDeploy website itself.
Therefore, I am forced to work my ways backwards to find how to extract elevation data from geotagged jpgs.
