Understanding GeoJSON Precision Reducer
Validity, topology and data quality
Round GeoJSON coordinates to a chosen decimal precision to reduce file size while preserving properties and geometry structure.
GeoJSON Precision Reducer 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
Reducing precision can collapse vertices or small shapes; review the result before replacing source data.
After GeoJSON Precision Reducer, compare changed feature counts, coordinates and shapes with the source. Automated cleaning can resolve a technical defect while introducing an unwanted geographic change.
