Local Resection

This method can be used to calculate the two or three-dimensional local coordinates for

the instrument station and the orientation of the horizontal circle from distance and

angular measurements to two target points.

The first target point always defines the origin of the local coordinate system. The second

target point, in conjunction with the first target point, always defines the local direction of

North or East (depending on the configuration settings).

For Resection and/or Resection Helmert, refer to "45.6.5 Resection/Resection Helmert".

Important features:

all coordinates calculated are local coordinates.

the first target point always defines the origin of the local coordinate system

(North=0, East=0, Height=0 (optional))

The second target point, in conjunction with the first target point, always defines the local

direction of North or East.

The following table explains the most common settings.
