- Open Google Maps.
- Enter a GPX file URL into the "Search" box.
- Click the "Search Maps" button.
- If desired, click "Link" to generate a link to to the current map view with the GPS data overlayed
For example, this GPX file contains a few points of interest for the Evergreen Mountain Bike Alliance Duthie Hill Trail area. By following the procedure above, one can easily create a Google Maps view with the GPS data overlayed. Very cool.
The example above is rather simplistic; the GPX file contains only a few waypoints. GPX files containing actual routes display as expected.
