In case you aren't aware, Strava has switched to OSM for its maps which is pretty darn handy.
(It's also knowing that all of the local MTB trails that I've surveyed / mapped are now properly on Strava.)
- Litost 11y agoAh thanks, it's been over a year since i did the initial evaluation, sounds like i'm overdue another :).
- mikekchar 11y agoThat is amazing! One thing I'm very interested in is the vertical data which Strava seems to be very good at interpolating from GPS traces. Do you know if they contribute that data anywhere?
- maxerickson 11y agoThey pull the elevation data from government data sets: https://strava.zendesk.com/entries/20965883-Elevation-for-Your-Activity#details https://strava.zendesk.com/entries/20965883-Elevation-for-Yo...
- mikekchar 11y agoThank you! That was very interesting. I had assumed that they were interpolating GPS data, but I guess not. It seems they are smoothing it, though. That being the case, perhaps I should write the program I was thinking of writing. Even though GPS elevation data is really, truly horrible I think you could probably use statistical techniques to get good data with enough GPS traces. Even routes that are mildly popular can have thousands, or tens of thousands of rides per year. Each one of those rides on Strava has GPX data associated with it. I'm sure it would be more than enough. Unfortunately, I have about a million other projects on the go :-P
