  It's not accurate. I mapped it from my house on Cabrillo St in the outer Richmond to 4th avenue and it says I need to climb 25th avenue then walk Geary instead of correctly telling me to use 23rd avenue that is completely flat.

    I think this comes down to the DEM they are using. I think it would have come out better if they had used USGS 3DEP DTM at 25cm.

    Edited: which apparently is hosted for free on AWS S3.

  Absolutely love the live profile updating when you swipe from flatter to shorter.

  > The slider runs along the whole trade-off between distance and climbing [...] Climbing is cumulative gain

  Another mechanism might be a kind of user-defined cost-curve, where a gradual climb to 10 might be preferred over a steep climb to 8, etc.

    You want OpenTripPlanner. Their triangle lets the user trade distance, climbing, and safe facilities.

  Doesn't Google Maps in bicycle mode already do this?

  Cool! Any way to toggle on street names on the map?
