Safe Geometry Simplifier
Simplify each GeoJSON feature independently and automatically retain the original whenever the simplified result becomes invalid.
Input
This validates each output feature but cannot preserve shared boundaries between adjacent records; inspect boundary seams after processing.

Understanding Safe Geometry Simplifier
Validity, topology and data quality
Simplify each GeoJSON feature independently and automatically retain the original whenever the simplified result becomes invalid.
Safe Geometry Simplifier 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
This validates each output feature but cannot preserve shared boundaries between adjacent records; inspect boundary seams after processing.
After Safe Geometry Simplifier, compare changed feature counts, coordinates and shapes with the source. Automated cleaning can resolve a technical defect while introducing an unwanted geographic change.
