Heatmap

View a map with TCX and GPX files overlayed on it.

How to use

First, place all the .tcx and .gpx files in a folder within this directory called input.
Next, get an API token from Thunderforest by signing up for a free account. In plot.js, replace {YOUR_API_KEY} with your API token. Alternatively, you can use any other free or paid tile server, just be sure to replace tileUrlTemplate and tileAttribution in plot.js
Then, ensure you have cargo and rust installed. Then, in this directory, run
```
cargo run --release
```
This will read each of the GPX and TCX files and convert them to data that can be plotted on a map. After this process has completed, open index.html in a browser to view your map.
