About KML and GEOJSON

KML is a markup language used to represent geographic data for visualization in tools like Google Earth. It supports placemarks, paths, polygons, and overlays, enabling rich geospatial presentations.
application/geo+json
Geographic data structure.
Conversion Notes
GIS format conversion preserves geometry and attribute data, but coordinate reference systems may differ between KML and GEOJSON. Our converter re-projects coordinates where needed. Complex curved geometries may be approximated as straight-line segments in formats that don't natively support them. Attribute field names may be truncated in legacy formats with character limits.
