Strava Heatmaps with the slide tool used to be a huge help for me - and many other mappers, I suppose - to quickly and accurately trace new tracks and roads. Unfortunately Strava now changed the access policy: Since March 2018 only logged-in members can see the high-res heatmap. This is not sufficient for mapping and the slide tool.

Since Strava highly profits of OSM - do you guys think it makes sense to get in touch with them and propose for example, that people with OSM login still can access high-res heatmaps with the slide tool?

I don't know anything about the ID editor but in JOSM I had to adapt the URL from




to make it work again, so I think it is just a matter of editing the layer definitions

In the ID editor you can see this url(1) works as custom layer, so they should update their settings

Thanks, this URL works! So the only problem left is Slide. It seems to take the low-res heatmap as input. So the result sucks.

So there are two things you could do: Report it to Slide (Strava?) Switch to Josm as editor, much powerful than ID

I use JOSM as well. But there is no slide add-on for it. It used to be very useful. Have a look: https://youtu.be/Ea-gLcmMbG8

Nice feature! I didn't know that, best way is contact the developers to fix this.

The new tiles work anywhere if you get them from the /tiles-auth/ directory on Strava's server (instead of /tiles/) and then append "Key-Pair-Id", "Signature", and "Policy" parameters that correspond to a valid OAuth token. I was able to get the necessary values from one of the cookies stored in my regular Web browser after having visited Strava's heatmap page.

It's an awkward workaround that takes a lot of copying and pasting (and which probably must be RE-done when the cookie expires), but in a pinch it might work for individuals who just want to get up and running in JOSM.

Hello Adam, can you please provide an example of URL? I've tryed something like this tms[3,11]:https://heatmap-external-{switch:a,b,c}.strava.com/tiles-auth/both/bluered/{zoom}/{x}/{y}.png?Key-Pair-Id=MYVALUE&Signature=MYVALUE&Policy=MYVALUE where MYVALUE are the respective cookies value, but the zoom level is the same as before.

(04 Apr, 15:29) Davide_sd

That looks right, you just need to increase the "11" to "15".

Note that if you're happy with the "bluered" color scheme, this cookie rigamarole is unnecessary, as ligfietser's tip (http://globalheat.strava.com/tiles/cycling/bluered/{zoom}/{x}/{y}.png) seems to work for now. But you'll need the cookie data if you want the "hot" or "gray" spectrum, both of which contain more visible data than "bluered."

Works for me!

Indeed Strava's GPS heatmap is very helpful for tracing hidden ways in natural elements (forests, woods, scrubs...). So, yeah i think that we should definitely remind Strava that they highly benefit of OSM and that it's still a good way for their costumers to know what kind of terrain it's expected on the GPS trace!

About their slide add-on in the optional iD editor, it's not convenient for plotting ways! You cannot create serious accurate ways according reality. I've tested it and seen what users do, it's discouraging: - not accurate and misleading
- doesn't take into account GPS offsets due to lack of signal, cliffs (will influence all GPS)...
- cross-ways whether in Y for or X or more are not respected
- adds useless nodes on straight lines/ways and overloads OSM with useless data and even removes precision on ways that are not straight...
- encourages people to plot ways without proper survey

Dare we suggest that using OSM tracker is a also a good alternative and available to all editors?

A GPS tracker is not a good alternative to the Strava Global Heatmap.

(13 Apr, 08:39) Tractor

I definitely find "Tractor"s statement questionable. We'd be hard at work, however, reaching the coverage of the Strava Global Heatmap, using OSM tracker (or gps uploads created in a variety of other ways). That said, Strava users in my experience often travel specific routes, leading some paths to stand out and others (often more important tracks) go completely unnoticed by editors relying solely on Strava. If we want the network of tracks in a given forest to be complete we still need to pull out our gps devices.

Perhaps also communicate with > https://josm.openstreetmap.de/ticket/16100 since they're struggling too.
