GPS track color coded with speed

Question

I am trying to find a way to to color code a GPS track with various data, such as speed, pulse etc using folium, but I have not found any solution in the documentation or the example. The is a online image of the effect I am trying to achieve.

Is this possible in folium currently?

Yes this is possible. You can use the ColorLine class for this:

https://python-visualization.github.io/folium/docs-master/modules.html#folium.features.ColorLine

We also have a Notebook with some example usage:

https://nbviewer.jupyter.org/github/python-visualization/folium/blob/master/examples/Features.ipynb#ColorLine

If you need more specific behavior you can copy the code from the ColorLine class and hack it yourself. It's basically a wrapper around two other classes: LinearColorMap and PolyLine.

We don't have a legend feature yet, if you would like to work on this you're most welcome. I'll refer to the original issue: #528.

I am embarrassed that I did not find this myself, but thanks a lot for taking the time to help me. :) The ColorLine was exactly what I was looking for.

Great! Good luck with it. I'll close the issue then.
