Features & Capabilities

The JOSM Strava Heatmap Chrome extension streamlines the use of the Strava Global Heatmap imagery within popular OpenStreetMap editors like JOSM and iD. Normally, accessing this imagery requires logging into Strava, copying several cookie values, and constructing a complex URL with key parameters that expire weekly. This extension automates that entire process by generating the required TMS imagery URL immediately after you log into Strava's heatmap page.

Key features include one-click retrieval of the TMS URL complete with necessary authentication parameters, easy integration with editors supporting TMS imagery, and quick updates whenever keys expire. It supports manual addition of imagery layers in both JOSM and iD editors, facilitating enhanced map editing with Strava's heat data. Whether you're a mapper who frequently utilizes Strava data or a casual editor looking to enhance your mapping workflow, this extension makes the process significantly easier and more efficient.

Is JOSM Strava Heatmap Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

JOSM Strava Heatmap requires a few sensitive permissions. Exercise caution before installing.
