Understanding Dissolve GeoJSON
Spatial relationships and derived geometry
Dissolve GeoJSON polygon boundaries by a property value or dissolve every polygon into shared coverage.
Dissolve GeoJSON evaluates where features lie relative to one another or creates geometry from that relationship. Geometry validity, boundary rules and compatible coordinate assumptions control the result.
How to verify the operation
Only polygon features are supported. Choose a field only when its values define meaningful groups.
Review Dissolve GeoJSON with feature counts, empty outputs, boundary cases and a few known examples. Confirm units and CRS assumptions before treating the result as authoritative.
