KML and GeoJSON are both popular formats for representing geographic features, but they tend to live in different ecosystems. KML is strongly associated with Google Earth-style workflows, while GeoJSON is widely used for web maps and APIs.
Quick comparison
| Topic | KML | GeoJSON |
|---|---|---|
| Typical use | Google Earth, sharing map overlays | Web maps, APIs, JavaScript tools |
| Encoding | XML | JSON |
| Styling | Often embedded | Usually handled by the map app |
| Tooling | Strong in Google ecosystem | Strong across modern web mapping |
