Edit GeoJSON geometry on a map

GeoJSON Cloud provides drawing controls for points, circles, and polygons, plus feature property editing and undo/redo.

Editing workflow

1. Open or upload a supported geospatial file.
2. Select a feature to inspect it.
3. Adjust its geometry or properties.
4. Export GeoJSON when the map is ready.

For advanced topology repair or coordinate reference system conversion, use a full GIS such as QGIS.
