GPS Visualizer

Make an HTML Map (Google/Leaflet) from a GPS file

Other forms:  Google Earth KML/KMZ JPEG/PNG/SVG Quantitative data GPX/textProfiles

This form will automatically draw your GPS data (or KML/KMZ file, or plain text data in CSV or tab-delimited format) overlaid upon a variety of background maps and imagery, using either the Google Maps API or Leaflet, an open-source mapping library.

Please note that creating a map with a very large number of waypoints (or very long tracklogs, especially if speed or altitude colorization is enabled) can cause your Web browser to grind to a halt. If you have thousands of markers, Google Earth might be a better choice.

If you don't have GPS data and want to interactively draw on a map, use GPS Visualizer's "sandbox" to create your own GPX or KML file.
