38 Local Resection
Local Resection is a resection in a local coordinate system.
The station coordinates and the Hz-circle orientation at the station
are calculated in the local coordinate system from measurements
to two points, where:
• the first point measured forms the centre of the local coordinate
system.
• the second point measured determines the direction of the
positive N-axis.
Basic Procedure

Local Coordinates of 1st target:

Direction of the local N-axis,
given by the 2nd target point.
