I am preparing for archeological fieldwork in Sudan. I recently came up with RTK equipment and software using RTKlib to export the real time corrected data (cm level) to QGIS via a simulated NMEA device.
However I checked the NMEA data flow and it includes elevations down to mm; in QGIS only one decimal is given. Is there any way to improve this and have the altitude information shown in cm as well?
Also QGIS applies geoid corrections but I wish to use ellipsoidal elevation. And finally right now I have to include the elevation data manually in the datamask for every point while saving. Is there a way QGIS can save the elevation in points and polylines?
