Vertex markers are displayed, and geodetic lines are displayed between the vertex markers.
Note I : the segment distance value is displayed at the mid point of the line(s).

The geodetic lines and vertex markers are updated to show the new distances. - Click on a vertex marker.

The vertex marker is removed and the lines and markers are updated to show the new distances. - To adjust a vertex marker by precision key-in, click on a vertex marker.
The latitude and longitude values are displayed in an Info Window. - In the Info Window, type in the new latitude and/or longitude values. Click Save.
