About GPS Visualizer

GPS Visualizer is an online utility that creates maps and profiles from geographic data. Input can be GPS tracks and waypoints, driving routes, street addresses, or plain coordinates. Output includes Google Maps and Leaflet maps, Google Earth KML, JPEG, PNG, and SVG images, and elevation or other profiles. The site also converts files between formats, such as to GPX or plain text.

Some features depend on outside services. Google Maps and Leaflet maps can use UK Ordnance Survey background tiles in Great Britain, but users must obtain their own OS API key. Geocoding works with Microsoft Azure Maps API keys, and elevation lookups use the Google Maps Elevation API and the USGS 3DEP service. The homepage also states that traffic is routed through Cloudflare for bot prevention.
