4.2.2. Measurements
Measurements are always
stored related to the station in GART-2000®
CE. With
Output
> Measurements the GPS measurements that were recorded on the chosen
station are listed.
In the first row the station measurement is listed. Afterwards all GPS
measurements are listed in chronological order.
The total station measurements are displayed with point number, point code,
marker type, horizontal and vertical direction, and slope distance. The target
height and, where applicable, the ex-centers of the target point are also given.
In addition to point number, point code, marker type and geocentric coordinate,
in the case of GPS measurement values the standard deviations, antenna height,
number of satellites, PDOP and fixing mode are also displayed. Any comment that
has been entered follows at the end of the line.
By means of the button <Edit>, the
measurement values that have been
marked can be edited. <Delete>
removes the marked values. The <Station>
button enables the user to switch between the different stations of the
project. With the <Print>
button, the measured values can be written to a file in formatted form or sent
to a printer. The relevant presettings can be selected under the menu item Initial
> Protocol.
Two
additional options are available for the output of GPS measurements. By
selecting the button <Geogr.>,
you can change the representation of the GPS measurements from Cartesian to
geographical. The button <Average>
effects the averaging of measurement values with the same designation. As a
result of this process, the averaged values are deactivated and marked with a ´#´.
The mean ascertained is inserted in the form of a new measurement value at the
end of the list.
The following data can
be edited:
| Point number (here: b1) | |
| Cod | Point code |
| VA | Marker type |
| CP | To define this point as a control point, activate the CtrlPnt checkbox. |
| H | Horizontal angle |
| V | Vertical angle |
| D | Slope distance |
| T | Target height |
| L | Longitudinal ex-center |
| Q | Transverse ex-center |
| S | Distance ex-center |

The button <Geogr.>
transforms the geocentric WGS84 coordinates (X,Y,Z) into geographic WGS84
coordinates (longitude, latitude, ellipsoidal height).
To
average multiple measurements,
mark the corresponding point number and click on the button <Average>.
GART-2000® CE
displays the differences of the averaged measurements and adds the
averaged value at the end of the list.
