I was wondering if anyone would be able to tell me the difference between UTM UPS GDA94 (set on my GPS) and GDA94/MGA zone 56, the nearest equivalent I can find in ArcGIS (under Projected Coordinate Systems - National Grid - Australia).
When I import GPS coordinates (UTM UPS GDA94) into ArcGIS in an excel file and onto a GCS GDA94 dataframe, I set the projection to GDA94/MGA zone 56, and they appear in the correct place on the map.
I'm still coming to terms with different coordinate systems.
