Re: [OSM-talk] Marking tight corners

[John Eldredge]

One risk factor that the two-dimensional geometry of OSM won't show is how 
a curve is banked. Unbanked curves are common, and I have encountered some 
curves that are banked with the low side of the curve towards the outside, 
very risky under wet conditions.

Zoom in!
  If there are enough nodes you should be able to see how sharp the
corner is ..
I use this is fog! You are travelling very slow and cannot see too far
.. the GPS map gives you more than you can see.

-
There are speed warnings - usually for fixed speed cameras. And some use
this for land mine warnings. No reason why the same method could not be
used for corner speeds ... but this is not part of the map but separate
POI.

Last time I looked at Google Maps, it didn't know about the train in my
area, and even showed some streets as continuous where in fact they were
blocked by the railroad (fence, no level crossing). Now it seems to have
the train but it's missing half the stations and there are still no
pedestrian crossings marked. I guess that's progress?

Yet another case of superior service from OpenStreetMap :)

yes, that is a bug in Maproulette. there are actually closer to 60k
tasks... I just didn't want it seem too insurmountable at first.
Thanks for participating!

I initially got that message too. But when you re-select the challenge, it
will correctly show you the remaining ~19.5k tasks

Never mind, Maproulette took me to different task that was completed.

Martijn,
I just checked and it appears the challenge is complete. Is that true? Less
than 22 hours after you announced it?

It is amazing what the community can accomplish is a very short time.

But that is not the 2007 coastline, is it?

Wonderful! It would be really great to have a yearly comparison 
somewhere. Like this, but with a date selector.
