7.COORDINATE MEASUREMENT
By entering the coordinate of station point, instrument height ,prism height and the
azimuth of Back-sight point, 3D coordinate of Measuring Point can be measured automatically.
7.1 Procedures of Coordinate Measurement
Measure the coordinates by entering the instrument height and prism height, coordinates of
unknown Point will be measured directly.
* Please setting coordinate values of occupied point refer to Section 7.2 “Setting
Coordinate Values of Occupied Station Point”.
* Please setting the instrument height and prism height, refer to Section 7.3 “Setting Height
of the Instrument” and 7.4 “Setting Height of Target (prism Height)”.
* Back-sight point is needed and then find the back-sight azimuth before the normal
coordinate measurement.
The coordinates of the unknown point are calculated as shown below:
Coordinates at occupied point
：（
N0
，
E0
，
Z0
）
Coordinates at the center of prism, originated from the center point of the instrument
： （
n
，
e
，
z
）
Instrument height :INS.HT Coordinates of unknown point
：（
N1
，
E1
，
Z1
）
Prism height: R.HT Vertical distance (Relative elevation)
：
Z
（
VD
）
N1=N0+n
E1=E0+e
Z1=Z0+INS.HT+Z
－
R.HT
Center point of the instrument (N0, E0, Z0+Inst.Ht)
