STAT GEOM QC
Quality control and geometric statistics for vector layers, with a correctness score and exportable report.
STAT GEOM QC analyses QGIS vector layers and detects quality issues: null or empty geometries, invalid geometries, self-intersections, overlaps/intersections between polygons, duplicates, small polygons (configurable m² threshold) and building inconsistencies (AGL > AMSL). It computes a weighted correctness score (0-100), shows a modern summary (gauge, indicators, breakdown) and produces an exportable report (HTML/CSV/JSON). Built-in QGIS actions: select flagged features, create a point error layer locating each issue exactly (self-intersection nodes for invalid geometries, representative point otherwise), and selective geometry repair (checkboxes) that writes the result to a NEW file without modifying the source layer. Native PyQGIS port of the STAT GEOM application, with no external dependencies.
