CRSmart QGIS 4 compatibility
QGIS 4 ready Active
Yes — CRSmart supports QGIS 4 (declared max version 4.99.0).
Uncertainty- and epoch-aware CRS / datum transformation assistant.
About
CRSmart turns CRS and datum transformation from a guessing game into a guided, transparent, uncertainty-aware workflow. It recommends transformation operations ranked by accuracy and area of validity, flags ballpark transforms, detects missing PROJ grids (with consented CDN download), handles epoch-aware (4D) transforms for dynamic datums, fits local site calibrations (Helmert / affine) with residual reporting, and repairs missing vertical CRS. All geodetic math goes through PROJ / pyproj. Every capability is exposed both as a Processing algorithm and via a dockable panel.
