I'm having an issue with GPS data accurately displaying on AutoCAD Map 3D live imagery. On several projects the data entered, whether imported from a Trimble unit or entered manually from coordinates, displays approximately 5 to 10 meters off the actually real world spot. The data is corrected and accurate before importing but when our field persons review the map it is slightly off.
Example: points that are plotted alongside a roadway show up anywhere from 5 to 10 meters onto the road.
I am using UTM 83 Zone 12 location. Not sure if my computer system is wonky or AutoCAD Map 3D needs to be calibrated???? Never heard of that.
Any suggestions?
