Shayne, osgdem adopts the coordinate reference system of the first input that you provide. So if your input is (for example) WGS84, and you are not building a geocentric database,I believe the terrain will be in a flat Plate Carre projection (X=Long, Y=Lat) with the origin at lat=0, long=0. If you are using --geocentric, the origin will be at the center of the earth.
