Strava does this

  Got a source? Strava segments in my area often have very wrong altitude data. Chicago is extremely flat yet there are segments that report gradients of over 10%, sometimes as much as 27%. I believe they are thrown off by buildings and the frequent elevated train tracks. https://www.strava.com/segments/1504604 https://www.strava.com/segments/1504604
