I am utterly new to GIS, so please bear with me if I am providing incomplete information here.
I have a DEM file (.dt2). What I am looking to do is as follows:
- take a series of points specified as lat, long
- calculate their elevations using the DEM data
- Output these points in as a list of ECEF coords
I need to do this in either GRASS or QGIS (using Python scripting, not the GUI).
I don't need a complete working code. I am only looking to be pointed in the right direction.
