#4386 new enhancement

Show lengths of ways (in kilometres)

When a way is selected, it would be nice to somewhere show its length in real terms.

Use cases:

  1. Sanity checking ("wait, this highway I selected is only 1.2km long?")
  2. Applying linear knowledge ("this road was sealed for the first 15km")
  3. Better sense of scale

We could possibly incorporate distances into various alerts, confirmations etc ("way moved 520m").

Is this harder to do than I think? Pythagoras on spherical-projected points gives a pretty accurate answer, right?

I would support this - it is along the same lines as my ticket #4319 'Show a scale on Potlatch2'

Certainly not difficult maths-wise. I don't think it's mainstream enough to want to show to every user by default, but it could happily live in the optional lat/long display.
