I have a large DEM dataset of the world's landmasses. The cell size is currently 1 arc-second. I need to resample the cell size to 250 meters. I can't for the life of me find out how to do this, but I need to in order to match it up with the cell size of other rasters I am using (which will make it easier to run some custom tools on them after converting to ASCII).
Is this possible to do? I understand there will be some error involved converting from degrees to meters, especially at higher latitudes, but since I'm converting from ~30 meters to 250 meters I assume that won't be much of an issue.
