I have a huge number of .DEMs and have been investigating how to process them into something useful.

Does anyone know how, or even if it is possible to read coordinates and elevation data from .DEMs using .NET? Specifically C#.

  • useful for what purpose?

You could use GDAL. I needed to go the other way, from grid to DEM.

  • To grids would be fine, im trying to create "calculated" contours from them... tricky stuff without C++ or FME as far as i can tell. Jul 5, 2011 at 13:26
