Topology Checker Pro QGIS 4 compatibility
QGIS 4 ready Active
Yes — Topology Checker Pro supports QGIS 4 (declared max version 9.99.0).
Detect, visualise & fix vector topology errors — with canvas markers, zoom-to-error, and step-by-step fix guidance
About
Topology Checker Pro scans any vector layer for geometry errors (null geometry, invalid geometry, self-intersections, duplicates, overlaps, gaps, dangles, multipart features) and displays the results in a clean docked panel. Key features: • Colour-coded markers drawn directly on the map canvas for every error • Click any error row to zoom to it and see a bright yellow highlight • Full-feature orange outline shows exactly which polygon/line is affected • Solution panel: plain-English explanation + numbered manual fix steps • One-click Auto-Fix for Invalid Geometry, Self-Intersections and Multipart • Prev / Next navigation through all errors • Export results to CSV • Works with QGIS 3.x (Qt5/PyQt5) and QGIS 4.x (Qt6/PyQt6)
