(3) votes
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)
