Distance Offset

FieldGenius allows you to do a distance offset to specify an offset forward or backward along the line of sight, left or right, and vertically up or down.

When you choose distance offset command and take a measurement, you will see the following screen:

From this screen you can specify if the offsets are with respect to the instrument or prism.

Offset buttons act as toggles, which allow you to easily define the direction the offset should be applied.
A negative offset will automatically be converted to a positive value.
The elevation of the point will be computed from your shot. This elevation will remain unchanged unless you specify a vertical offset.
The distance is assumed to be horizontal.

Forward / Back Offset

Enter the offset distance from the shot position to the new position.

Right / Left Offset

Enter the perpendicular offset distance from the shot position to the new position.

Up / Down Offset

Enter the vertical offset distance from the shot position to the new position.

Store Point

After you have entered your offsets you can press the Store Point button to save the point

Raw Record

A sideshot (SS) record will be computed to represent the shot. The new SS record will use the original observation plus any offsets defined in the distance offset screen.
