GGNSS height transfer step-by-step
- Open the Coordinate System app.
- From the Coordinate System Menu, select Other Methods > Height Transfer.
Select a coordinate system, either from the project or a pre defined one. Tap 
to accept.
If a coordinate system is already present in the current project, that step is skipped. - Select an existing point, either from the map or the Point List, to get the height from or input height value directly.
- Tap
to accept the local reference height or measure further points. 
Define Measure Mode in the Status 1 menu. According to the setting selected, the measure key may differ from the description within this guide. 
When at least two points have been measured, the Residuals screen can be accessed by
tapping
. - Remove inaccurate measurements from the calculation. Tap
to confirm.
- To finish the localisation tap OK in the Confirmation screen. Then tap
to save the new Coordinate System, either with the proposed name or a user defined one.
- Confirm the next information screen. From now on all points measured will have the reference height applied.
- When more than one point has been measured to define the local reference height, a best fit solution will be applied and used as the height difference. This means that the local reference height is balanced from the measured heights and the height difference equals the height of the newly measured point minus the local balanced reference height.
