Interpolate GPS

The Interpolate GPS option allows you to select two points and rubber-band all data points between the known GPS coordinates.

When survey data is modified, including reversing survey segment direction or rearranging segments, survey data showing in the Chart, Map, and Table panes may become out of date. When this happens, Out of Sync - Refresh Survey will appear in the Chart's title bar. Click to refresh the survey and load the updated data in all of the panes.

Complete the following steps to create an interpolation:

  1. Move your mouse to a point on the chart and right-click on the chart to open the options menu and select Interpolate GPS.
