GE 5180 Exercise Digital Topography and satellite imagery ...

Instructions on how to overlay an ASTER image on digital topography with ArcGIS: In order to overlay an ASTER image on a DEM in ArcGIS, the ASTER image must (1) have the same projected coordinate system as the DEM, and (2) be in a format that ArcGIS can read. ArcGIS cannot read HDF files, so convert the image to an .IMG file (ERDAS IMAGINE). ................
