- Strava cyclists curious about ride surfaces
- Worth noticing
- It samples GPS tracks every 20 metres, smooths over about 100 metres, and says it is tuned on rides in Czechia.
Field notes
The described workflow matches GPS points to the nearest mapped road or path, smooths those matches, and uses OpenStreetMap surface tags to estimate a ride’s mix. Its roughness scale assigns asphalt 0 and rock 5, then averages by distance; the example classifies a score of 16 as mixed. The site says missing surface tags may require guesses and that rides without GPS or mostly off mapped roads are skipped.
