Survey workflow (set base / rover, collect control, and solve calibration) will define the projection.
[Select a Mapping Plane>]: Tap to launch the
Select Coordinate System screen. You must select a mapping plane
zone to continue. Once you have selected a coordinate system, the Start Survey wizard advances to the next screen
Don’t Ask Me Again: Check to start the survey with the method selected above, and subsequent instances of the start
survey workflow will skip this prompt and start with the chosen method.
