This is an example of how GPX files can be displayed using pointMapper. If you have GPX files to display, download the source of this file for ideas on how to do that. GPX files will vary as to how much metadata and waypoint data are included, and map applications will differ as far as what metadata and waypoint data should be displayed. The possibilities are endless, and this is just a demo. This interactive method of displaying GPX files probably won't work for files with more than a couple of hundred waypoints.
