CRS Doctor
Detect and fix coordinate reference system (CRS) problems across all project layers in one click.
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.
