Title: Elevationprofile

Thanks to the great work of Espen Isaksen, and all the great libraries available we now have a pretty decent elevation profile implementation for you to check out. You'll need elevation data and some dependencies to use it, see the last part of [[Installation]] for more info.

At the moment there are some drawbacks:

1. We cannot render complex routes, this is decribed in the new help page entry.

1.1. The error message does not give a clear description of what the problem is.

2. Direction of route is determined by elevation of end points (also described in help entry).

3. The raster code is perhaps somewhat outdated/redundant.

There is also a bug:

A profile for an unrelated route can show up in route information view if you're impatient and switch to another relation before the profile has finished rendering. Do the following to reproduce:

1. Open up a route information view on a route that will render a profile, but hasn't been cached, preferably a long one that takes some time to render.

2. Don't wait for it to render, but go back to the list and look at another route.

3. Notice that you'll be seeing the elevation profile fo the route that you opened in 1.

Espen will attempt to fix this when we have more feedback on the implementation as a whole.
