Understanding Polygon Geometry Repair
Validity, topology and data quality
Repair common self-intersecting GeoJSON polygon geometry by splitting kinked shapes into valid polygon parts while retaining properties.
Polygon Geometry Repair checks or changes structural properties of spatial data. Geometric validity concerns rules such as ring closure and self-intersection; factual accuracy requires separate real-world verification.
How to review a repair
Automated repair can change feature shape and split one record into several; compare output visually before replacing source data.
After Polygon Geometry Repair, compare changed feature counts, coordinates and shapes with the source. Automated cleaning can resolve a technical defect while introducing an unwanted geographic change.
