CRS Doctor QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Detect and fix coordinate reference system (CRS) problems across all project layers in one click.
About
CRS Doctor scans every layer in your project and reports CRS health with severity levels: missing or invalid CRS (critical), suspicious extents suggesting a wrongly assigned CRS (critical), layers not matching the project CRS (warning), and geographic-CRS layers where distance/area measurements would be computed in degrees (warning). Each issue comes with a one-click fix: assign a CRS, reproject a single layer, or batch-harmonize the entire project into one target CRS (with automatic UTM zone suggestion). Vector layers are reprojected with the native engine and raster layers with GDAL warp. All fixes are non-destructive: original layers are preserved and reprojected copies are added to the project. No external dependencies required.
