12. Intersection
Intersection 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 intersection measurement overwrite the N, E, Z data of the instrument
stattion,
◆ Inputted known coordinate data and calculated data could be recorded in the current
coodinate file.
◆ Max number of known points is 5
Known point P1
Known point P2
Occupied point P0
Known point P3
Known point P4
