## Questions fréquentes

### What is a KML file?

KML (.kml, Keyhole Markup Language) is an XML-based format for geographic data, developed by Keyhole (acquired by Google) and standardized by the OGC. It stores points, lines, polygons, styles, network links and overlays, and is the native format of Google Earth.

### Are my KML files uploaded?

No. Data you open from your device stays on your device and is rendered locally on the map. Only the public sample file is requested from the server.

### What is the relationship between KML and GeoJSON?

Both store geographic data. KML is XML-based with richer styling and Google Earth integration. GeoJSON is JSON-based and is the web mapping standard. The viewer converts KML to GeoJSON internally for rendering.
