Introduction
This manual describes the "Local
Resection" program of the TPS1100
Professional Series.
Local Resection
The program can be used to deduce
the three-dimensional 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.
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 positi-
ve N - axis.
Station Data
