About JOSM Strava Heatmap

This browser extension makes it easy to use the Strava Global Heatmap in JOSM. Accessing this imagery externally requires a set of key parameters that you obtain by signing into the Strava website, copying the values from several cookies which must be included with imagery requests from JOSM in a custom header. The keys expire frequently and the process must be repeated. This extension gathers the url and cookie values automatically so you can quickly open the imagery in JOSM. Instructions ------------------- 1. Visit strava.com/heatmap and log in – sign up for a free account if you don't have one 2. Optional - Select the heatmap color and activity type you want to use 3. Click the button pictured below 4. Click the Open in JOSM button (JOSM, Remote control must be enabled) Using the imagery in other applications ------------------------------------------- The raw URL pattern and cookie header strings are also exposed for other potential uses. These can theoretically be used in any mapping application that supports adding a TMS imagery source with a custom cookie header like JOSM does.
