12. Resection
Resection program is used to determine the coordinates of an instrument station
(unknown) by measuring several known points. Coordinate data in memory could be read.
Input
Coordinates of known points: Xi, Yi, Zi
Measured HA: Hi
Measured VA: Vi
Measured distance: Di
Output
Coordinate of occupied data: Xo, Yo, Zo
NOTE:
◆ All N, E, Z value or only Z value of the occupied point is calculated by measuring
known points.
◆Coordinate resection measurement overwrite the N, E, Z data of the instrument
occupied point, while elevation resection measurement overwrite Z data only. Perform
resection measurement, see “§ 12.1 Coordinate Resection” and “§ 12.2 Elevation
Resection”.
◆Inputted known coordinate data and calculated data could be recorded in the current
JOB.
