What two additional steps are required when using polar coordinates to map a scene in which elevation data are required?

The Correct Answer is

First, the difference between the datum point elevation and the sighting instrument must be determined (i.e. the height of the instrument above the datum point). The second additional step involves properly placing the sighting device in the scene, ensuring that the sighting device is at a higher elevation than any evidence items.
