Previously, accessing Strava heatmap imagery required a tedious process of extracting Strava website cookies and generating a temporary URL that would expire after a week.

The JOSM Strava Heatmap Extension simplified this process, but due to the lack of support for custom overlays in the iD editor, users could only add the URL as a custom background.

With this extension, you can now automatically access all Strava activities as Heatmap overlays, eliminating the need for manual URL management.

To learn more about using the Strava Heatmap in OpenStreetMap, visit the Strava wiki.

Currently, there are no plans to support other editors, as this extension is designed specifically for iD.

• For RapidId, refer to the RapId Power User Extension.
