GeezMo76 Posted October 27, 2009 Report Share Posted October 27, 2009 Can anyone tell me what the .DEM files or used for. I think they have something to do with better map resolution, maybe. Anyways, do I need to keep the 118 mb US dem file if I want to use the NorthAmerica_low_2008_03_25.dem file that is 181mb since it covers the same region or not. I 'm starting to run out of space and have files in the DEM folder that aren't needed. Quote Link to post Share on other sites

Not really needed, and unless you live in a mountain area you won't see much difference with or without them (or with a smaller one). Quote Link to post Share on other sites
