GitHub - janbergman/gpxtcx2map: A single html file to align a .gpx or .tcx track to a (scanned) map (.png). The track can have or not have any controls (laps from a Garmin GPS watch). You just click on the track or the controls and drag the circles to the correct place on the map. Just aligning two points is often enough for a gross alignment. To download press "d" key.

Upload map and GPS track through the menu.
Two point align: Roughly adjust the track to the course by clicking on a control ring or clicking on the track and then dragging to its position on the map. Do the same for another point as far away from the first as possible.
Fine-tune with more points if nessesary.
If you change your mind, you can click again.

Note: the rings are a bit hard to see, so it may be a good idea to zoom in a bit when adjusting.

When you are finished, you can download by pressing "d" on the keyboard.

This program was "vibe-coded" with Gemini CLI and OpenAI Codex.
