Overall I like what I see in the MapRoulette. The challenge is that it
becomes difficult to monitor the local area. Most changes that appear
in the history have 5-15 pages of ways listed, scattered across the
country or world. I reviewed several in my area and found one that

Hi all,
I've made the same experiment as James did. Got 7 of 20 tiger-specific
errors, 6 of which where obvious to fix. I would fix 5 other
user-introduced errors. And wouldn't touch 9 left.
Indeed, MapRoulette interprets many non-obvious cases as errors.
Ivan.

M, no, there are some counties in NY which were in excellent

M, no, there are some counties in NY which were in excellent
condition, and which haven't needed any editing at all.

There is a TIGER editing page at
http://wiki.openstreetmap.org/wiki/TIGER_fixup which is a good start. I'm
sure it can be improved.
Having edited connectivity errors across the US, I can say that the large
majority of fixes are obvious and simple. In general, (and I realize I'm

But (that might be what Frederik already said), remember that the rest
of the community outside the US is quit unfamilar with TIGER import
issues in detail.
For example, I tried to fix a bug, but it tu

That's true. But in the US disconnected roads are produced

Hi Martijn,
Besides ways with close ends, here are thousands of (partially)
duplicated roads, mostly along county boundaries that kill road
network topology as well. They typically appear as more than one roads
having nodes at the same positions. Does MapRoulette catches these
ones too?

Hi all,
MapRoulette (http://maproulette.org) is back with a new challenge:
~68,000 connectivity bugs in the US to be fixed. These are ways ending
very close (<5m) to another way, which means they should likely be
connected, although there are of course exceptions. Which makes it an
ideal MapRoulet
