A KML file is a mapping file format used to display geographic data in programs like Google Earth, Google Maps, and GIS software. KML stands for Keyhole Markup Language: a text-based XML file that describes locations, shapes, and map features for visual presentation.
Can contain: points/placemarks, lines/paths (routes, roads, trails), polygons (boundaries, areas), image overlays, 3D models, and custom styling.
Common uses: mapping trails and routes, property/land boundaries, planning projects, and sharing map data visually.
Opens in: Google Earth (desktop/web/mobile), Google My Maps, GIS software (QGIS, ArcGIS), and many online map viewers.
KML vs KMZ: KML is a plain map file; KMZ is a compressed KML plus any attached images/icons/resources.
A GPX file is a standard GPS data file format used to record and exchange location information between GPS devices, mapping software, and navigation apps. GPX stands for GPS Exchange Format: it stores GPS data in XML text format, so it's readable and widely compatible.
Can contain: waypoints (single saved locations), tracks (recorded travel paths with timestamps), and routes (planned paths).
Typical uses: off-road riding and trail mapping, hiking/biking/running routes, marine navigation, trip logs, and sharing location data between devices.
Opens in: GPS devices (Garmin, etc.), apps like OnX, BackCountry Navigator, Polaris Ride Command, and many phone navigation apps.
Key difference vs KML/KMZ: GPX is GPS-data focused (tracks, routes, waypoints); KML/KMZ is more about visual map presentation (labels, styling, imagery).
