Setting Instrument Station Coordinate With Resection Measurement - Sokkia im-101 Operator's Manual

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.

• 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.
