KML Files:

GPX Files:

A KML file is a mapping file format used to display geographic data in programs like Google Earth, Google Maps, and GIS software.

Simple explanation

• KML stands for Keyhole Markup Language

• It’s a text-based XML file that describes locations, shapes, and map features

• Used for visual presentation of geographic information

What it can contain

• Points / Placemarks (pins with names, descriptions, photos)

• Lines / Paths (routes, roads, trails)

• Polygons (boundaries, property lines, areas)

• Image overlays (custom map images draped over Earth)

• 3D models and shapes

• Custom icons, labels, colors, and styling

Common uses

• Mapping trails, routes, and off-road tracks

• Property mapping and land boundaries

• Planning projects or marking locations

• Creating Google Earth map presentations

• Sharing map data visually

How to open

• Google Earth (desktop / web / mobile)

• Google My Maps

• GIS software (QGIS, ArcGIS)

• Many online map viewers

KML vs KMZ

• KML = plain map file

• KMZ = compressed KML + 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.

Simple explanation

• GPX stands for GPS Exchange Format

• It stores GPS data in XML text format, meaning it’s readable and widely compatible

• Commonly used for sharing rides, trails, routes, and waypoints

What it can contain

• Waypoints – single saved locations (like pins)

• Tracks – actual recorded travel paths with timestamped coordinates

• Routes – planned paths you intend to follow

Typical uses

• Off-road riding and trail mapping

• Hiking, biking, running routes

• Marine navigation

• Recording trip logs

• Sharing location data between devices or apps

How to open

• GPS devices (Garmin, etc.)

• Apps like OnX, BackCountry Navigator, Polaris Ride Command

• Many phone navigation apps

Key difference vs KMZ/KML

• GPX = GPS data focused (tracks, routes, waypoints)

• KML/KMZ = more visual map presentation (labels, styling, imagery)
