Add elevation profile to hike entry page.

Opened this issue · 2 comments

GPX data should already contain elevation data. A couple of questions still remain:

  • How to cleanly represent this data
  • How to handle out and back hikes?

From what I've seen, elevation in GPX data can't be trusted. There are jumps up and down by several meters depending on how many satellites the GPS device can see. My Garmin eTrex 20 does that a lot. I would use an elevation service like the MapQuest Open Elevation Service.

No problem with out and back hikes - the graph will just be symmetrical.

Very good point about the GPX data. I've been seeing that too when calculating hike distance, the numbers are inflated because of the noise. The service looks good, will have to give it a shot.

Agreed about the out and back hikes. It's actually nice to have the visual reminder that the hike is the same forwards as backwards.
