Map Shift
Map Shift is used to shift the onscreen map and account for time base inaccuracies with lower accuracy GPS
receivers. This is done by doing a quick survey and creating a reference point. Any time the user would like to
adjust the map to fix GPS drift inaccuracies, they can go back to the reference point and perform a survey to
shift to the current position.
Map Shift General Guideline
For Map Shift to be successful, it is suggested that a reference point be set before beginning a field operation. That way any
time the vehicle leaves the field or is shut down for an extended period of time, the reference point can be used upon
returning to the field operation.
Enable Map Shift
With the map shift option checked, the map shift icon will become available when in full screen view on the mapping
screen.
Shifting the Map
1. Press the map shift icon to access Map Shift
Options.
2. Determine a good location to create a
reference point. For Map shift to work
properly, it is vital that the GPS receiver be
able to get back to the exact same point each
time a shift is required.
3. Once a spot is located, press “Set” on the Map
Shift options page to begin the 10 second
survey.
4. Once the survey is complete, the reference
point will be set. On the Mapping Screen, the
reference point is shown by a blue pin drop.
