GeoSTAT AI
Automatic quality analysis of vector layers: invalid geometries, duplicates, small/thin polygons, self-intersections, empty attributes... with a quality score out of 100 and an HTML/PDF report.
GeoSTAT AI is a quality-assurance (QA/QC) plugin for QGIS. To use it: open the plugin (toolbar icon or Vector menu), select a vector layer, tick the checks you want to run and adjust thresholds if needed, then click "Run analysis". The plugin automatically scans the layer and detects invalid geometries, duplicate features, very small polygons, very thin polygons, multipart geometries, empty attributes, very short segments and self-intersections. It computes a quality score out of 100 and generates a detailed report with statistics and recommendations, which you can export to HTML or PDF. Interface available in French and English.
