Hello and thank you for your post.
Strava utilizes OpenStreetMap, an open-source project that distributes geographical data for the entire world, alongside our own heat/popularity and other unique data, to create both the visual experience for maps as well as to help inform routing decisions and points of interest shown on the map. For more on this, see https://wiki.openstreetmap.org/wiki/Strava. It costs nothing to contribute to OSM, which means that you can help contribute to better geo data on Strava and make for a more informed, safer, and delightful routing experience for your fellow athletes!
