Was ist GeoJSON?
Dialekt für Geodatentypen der textuellen "JavaScript Object Notation" (JSON).
Siehe auch Geobuf und OGR-Konverter.
Notizen:
- Currently, GeoJSON is supported as output format of services implemented by FeatureServer, GeoServer and CartoWeb3.
- Ein einfacher GPX zu GeoJSON Konverter: gpx2GeoJSON
- Binär codiertes GeoJSON: GeoBSON (.geobson) and Arc GeoServices BSON (.arcbson) BSON-encoded GeoJSON and Arc JSON, see http://bsonspec.org/#/specification
- Bei QGIS kann mit Drag&Drop ein GeoJSON File dargestellt werden(?).

Reducing unnecessary digits with regex
Use this regex to reduce to 5 digits in lat/lon coordinates. Replace by group "\1" e.g. in Notepad++. See https://regex101.com/r/eR4sU3/3 :
([0-9]*\.[0-9][0-9][0-9][0-9][0-9])[0-9]*
