[Qgis-user] Batch convert nonsense-coordinates from DWG?

[johannes.kroeger at wheregroup.com]

Hi guys,

those CRS' are kind of the underdogs but actually kinda useful as they 
encode the UTM zone in the values. Check out Javier Jiminez Shaw's great 
overview on DACH CRS' from FOSSGIS 2025, it covers those as well:

Cheers, Hannes
