GNSS localization
| 
| 
Define the method to use for transformation of the GPS coordinates in plane coordinates and vice versa.
Without an assigned GPS localisation, only the geographic coordinates of the points are recorded. A visualization of the points in the graphic window is impossible.
Click Job.
Click Coordinate system.
Click GNSS localization to open the page with the method to transform the GPS coordinates.
The available methods are:
No system: no coordinate system is applied.
Local - Single point: a system is created based on a local projection referred to one origin point.
Local - Site calibration: a system is created based on several points with known geographic and local plane coordinates.
Cartographic system: for the transformation from geographic to plane coordinates a cartographic system is used. The system can be manually entered or selected from a list of predefined systems.
Reference axis: a system is created based on the measurement of a point of origin and the measurement of a second point which defines the direction of the axis.
2 Reference axis: the position and orientation of the station are determined by measuring four reference points. The points define two axes which, intersecting each other, determine the position of the station.
Vertical elevation: after a system has been defined, the software allows to choose what system use to calculate the elevation.
When the GNSS localization is selected or changed, the software asks if the points already available in the job, with a valid latitude and longitude, have to be recalculated in the new system.
All points: recalculates the coordinates for all points in the job with a valid latitude and longitude in the job.
No points: coordinate of points are not recalculated in the new system.
GNSS points: recalculates the coordinate only for points measured with a GNSS receiver.
TPS points: recalculates the coordinate only for points measured with a total station.
Imported points: recalculates the coordinate only for points imported in the job.
Other points: recalculates the coordinate for points calculated, for example in COGO, or manually entered.
