hiddenzone 2 Posted May 31, 2015 (edited) ASTER GDEM v2 has a 1 arc-second grid resolution, or 30 meters approximately. Interpolating raw data into height map with 10mx10m or smaller grids will generate more details, but aren't these details false? When does it make sense to interpolate raw satellite DEM data? BTW: What if I make a 4096x4096px, 30mx30m terrain of which size is 123kmx123km? And how about an 8192x2048px, 246km x 62km terrain? (PS: Why 8192x8192px terrain errs?)

wantafanta 13 Posted June 5, 2015 i would do whatever changes i wanted to do to the DEM after importing it into L3DT, then smooth or edit as neccesary. IMO dont mess with the interpolation settings in any GIS app unless you understand what your doing.... personally i have no clue how those apps work aside from the basics so i just stick to L3DT to change cell size or overall size of my heightmaps Share this post Link to post Share on other sites
