GPX - GPS Exchange Format. GPX (the GPS Exchange Format) is a light-weight XML data format for the interchange of GPS data (waypoints, routes, and tracks) between applications and Web services on the Internet. OGR has support for GPX reading (if GDAL is build with expat library support) and writing.
For this example, I'm going to use some waypoints from ClubTread, and a route from EveryTrail. This assumes you want 2 data sources (any number is fine). At the bottom of both pages, you will find download links. GPX files are the most widely accepted file format for various tools (KML is probably second). For this guide, we'll just stick with GPX files. It's important to know that they only contain a small set of objects, like tracks, waypoints and a few others. They do NOT contain the image of the map you overlay them on.
