I have been trying to use ASTER Data to use as a DEM in CityEngine. I also converted it to a geotiff in Globalmapper just to make sure it got the coordinate data. I found it surprising that CityEngine is prompting me for a coordinate system. I thought this would be embeded in the GeoTiff. None of the selections I have made have worked, they produce obviously wrong terrain. Anyone know what I should be choosing for this?
