[josm-dev] validator suggestion: way ends close to other highway

[Greg Troxel]

I've been running the validator over my whole town (roughly 6km x 6km),
trying to fix all the real issues.  Overall it's very helpful.  Except
for the case below, I am able to understand quickly what it finds
problematic.

(I find that the "disconnected ways" step takes a very long time,
perhaps minutes, compared to a few seconds total for everything else.
So I've disabled it for now.)

I get a lot of warnings for "way ends close to other highway".  I get
the general concept - maybe it should be connected - but it seems overly
aggressive about warning.  So maybe I am misunderstanding it, but my
suggestions are:

  * make the distance configurable (so that when faced with 250
    warnings, one can set this to 0.5m, or 1m, and find the most likely
    cases that need fixing, as opposed to micromapping where you really
    can't go from the parking aisle to the nearby road).

  * in the warning dialogue/highlighting, highlight not only the end
    node, but the way that is too close, and put the distance in the
    dialogue box.

My second suggestion is because I'm often (98% of the time) unable to
figure out what's wrong.  Sometimes the way end that's highlighted is
connected, but is perhaps near some third way that isn't connected.

If people think this validation step doesn't produce lots of false
positives, I can send a specific example.
