13.2 Setting Instrument Station Coordinate with
resection measurement
Resection is used to determine the coordinates of an instrument station by
performing multiple measurements of points whose coordinate values are known.
Registered coordinate data can be recalled and set as known point data. Residual
of each point can be checked, if necessary.
Entry
Coordinates of known point : (Xi, Yi, Zi) Station point coordinates : (X0,Y0, Z0)
Observed horizontal angle : Hi
Observed vertical angle
Observed distance
• All the N, E, Z or only Z data of an instrument station is calculated by measuring
the known points.
• Coordinate resection measurement overwrites the N, E and Z data of the
instrument station, but height resection does not overwrite N and E. Always
perform resection measurement in the sequence described in
"13.2.2 Coordinate Resection Measurement" and "13.2.4 Height Resection
Measurement".
• Input known coordinate data and calculated instrument station data can be
recorded in the current JOB.
