Line Intersection Finder
Find pairwise intersections among GeoJSON line features and export crossing points with the indexes of both source lines.
Input
Coincident line overlap is not represented as an area or line result; validate duplicate and overlapping linework separately.

Understanding Line Intersection Finder
Validity, topology and data quality
Find pairwise intersections among GeoJSON line features and export crossing points with the indexes of both source lines.
Line Intersection Finder 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
Coincident line overlap is not represented as an area or line result; validate duplicate and overlapping linework separately.
After Line Intersection Finder, compare changed feature counts, coordinates and shapes with the source. Automated cleaning can resolve a technical defect while introducing an unwanted geographic change.
