We are accurately surveying points in Finland, Europe, with an RTK Calibrated Surveyor Kit, using SW Maps and a national RTK service. The exported point shapefile seems to be in a WGS84 coordinate reference system, as shown by QGIS on examination. However, we need to have a good accuracy, and an extra ~1 m error between the two coordinate reference systems is unacceptable to us. How do we record and export points as intended in Europe and by our local RTK service, i.e. in an ETRS89 system? Or is it so that there is no error in any case? I.e. is it possible that while the layer/shapefile itself is in WGS84, the points themselves are keeping to ETRS89, as supplied by the RTK service? At this point, I reprojected the shapefile in QGIS to ETRS89, but it’s hard to judge about the accuracy as compared to the proper European coordinate system.
- Are you in RTK FIXED mode when taking the measurements?
- Are you using the ETRS89 mountpoint?
- Are your other maps in ETRS89 or in local Finnish coordinate system?
