Polar coordinates
coordClass = “AGridBearing”
Coordinates are displayed and entered in Polar coordinates measured from the position entered during Polar (View > Axes).
Example: Digitizing a fence with reference from a single location/point of interest.
First change the format of the Status Bar to show Polar Coordinates.
If you cannot see this menu, right click on the Status Bar and select Position.
The next step is to define where the Polar Coordinate or point of interest is located (this could be a telegraph pole, tree, etc from which each vertex to be digitized will be referenced from.)
Use Polar (View > Axis) to enter a position.
Once the Polar Coordinate value is set the cursor position values in the position bar will be relative to that value, even after vertices have been created.
