On my previous post on my ASTER issue, ASTER extent or projection issues. I decided to revisit on this issue. I am still puzzled as to why my ASTER has geographic coordinate system on its extent but the Spatial Reference tells me it is in UTM Zone 13 Northern Hemishphere and the datum shows me the Datum Not specified based on GRS 1980 spheriod. This is done in my office. The ASTER I download came from this website: USGS EarthExplorer
Now, I have ArcMap 10.1 at home and the extent and the projection shows me they are in the correct extent UTM numbers and correct projection.
How can one ArcMap 10.1 in my office and ArcMap 10.1 at home showed me two different extent numbers: One in geographic coordinate system and Projection UTM numbers ??
What could have cause them to show different extent numbers and why ? Could it be the installed change something within the ArcGIS program ?
For your information: My ERDAS 2011 show me the ASTER is in UTM meters and UTM Zone 13 projection and were able to overlay with polygons.
I will see if I can uninstall and reinstall my ArcGIS to see if it is the same results.
