I want to edit the GPS result in ArcGIS, but I found that there is a problem. I set the wrong unit while I used the GPS outside , and the unit is "degree". Although the coordinate system is correct, I still cannot change the unit to meter.

Is there any method that I can edit the unit to meter in GIS ? (or QGIS?) Thank you very much!

In what format are the data from the GPS? Have you downloaded as GPX? –  Simbamangu Jun 16 '12 at 14:09

1 Answer 1

What values were actually stored? Are they in the range of -180 to 180 (longitude) or -90 to 90 (latitude)?

If so you can't just edit the coordinate system, you'll need to project to the correct one.

If on the other hand you just need to redefine the feature class's coordinate system, without changing the stored geometry, you can use the Define Projection tool, or set the coordinate system in the feature class properties.
