About KMZ (.kmz)

KMZ is a zipped KML file — the same placemarks, paths and polygons, plus any bundled icons or ground-overlay images, in one smaller download. Opened by the same viewers as KML: Google Earth and Google Maps.

About GPX (.gpx)

GPX (GPS Exchange Format) is an open XML format for waypoints, tracks and routes, with optional time, elevation and extension fields. It's the universal GPS interchange format — read and written by Garmin Connect, Google Earth, OsmAnd, Strava, komoot and nearly every GPS app or device made since 2004.
