I have a few points collected in Google Earth, and now stored in a CSV file:

lat long
47.17347661 7.584905937
47.17347661 7.584905937
47.17756055 7.578652797
47.17756055 7.578652797
47.18636237 7.57629175

and I would like to reproject them to LV95 LN02. I have tried several times to both use "Export > Save Features As > CRS: LV95" or with the function "Processing > Toolbox > Reproject Layer".. but either I get errors or the projection does not work... Any suggestion?

  1. Load the csv as a Delimited Text enter image description here
  2. As mentioned in the comments by J.R. - Do some visual checks if the data is where it should be - if they are off check the CRS or if Lat/Lng are swapped etc.
  3. Export the data (Right Click the new layer --> Export --> Save Features as) enter image description here
  4. In the properties set your CRS to EPSG:2056 (or any other CRS you want to export to) change the Format to CSV (or any other format). If it is CSV set the GEOMETRY property to AS_XY and the SEPERATOR to your choice. enter image description here

Result:

    You may add a step between 1 and 2 to check that the import is "right" (right CRS, no Lat/Lon inversion, right field type, ...)

  • opsss......@Bernd Loigge, I have followed exactly your procedure, but I got an error once I was exporting the new csv file (it did not allow me to create the csv file).... Export to vector file failed. Error: Feature write errors: Feature creation error (OGR error: Failed to create ./reprojected_coordinates.csv: Read-only file system) Feature creation error (OGR error: Failed to create ./reprojected_coordinates.csv: Read-only file system) Only 0 of 5 features written. Storing metadata for the specified uri is not supported

  • Well, it looks like it is a Read-only file system - so you don't have the rights to export the CSV (at least not to the path you specified)
