Introduction
This manual describes the "LOCAL RESECTION"

Two points are measured from any instrument station.
The first point measured forms the centre of a local
coordinate system (N=0; E=0; H=0). The second point
measured determines the direction of the positive N -
axis.
The distance between the two points must be at least 50
mm
The program can be used to deduce the three-dimensio-
nal local coordinates for the instrument station and the
orientation of the horizontal circle from measurements
to 2 target points. To compute the position coordinates,
at least 4 elements (2 distances and 2 directions) are
necessary.
For simultaneous determination of the local station
elevation, height of instrumentand height of reflector
must already have been input.
The program allows measurement in single or dual-face
mode.
