Uncertainty- and epoch-aware CRS / datum transformation assistant.
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.
