Hi everyone, I have just seen on the blog of Geofabrik ( http://blog.geofabrik.de/?p=96 ) that the awesome OSM-Inspector routing debug layer is now available for the US as well.
It can be found at http://tools.geofabrik.de/osmi/debug.html?view=routing_non_eu&lon=-97.93506&lat=37.41729&zoom=6&opacity=0.98 It is a debug layer that highlights roads and paths that end very close to each other, but aren't actually connected (i.e. don't share a node). As getting the connectivity right is essential for any successful routing application, these "bug reports" are quite important to fix in order to try and improve routing capabilities of OSM data. Overall, currently there are a lot of errors in connectivity. Some of them are import specific (county boundaries in TIGER?), but as one can see from the high number of bugs in Europe, broken connectivity is a fairly general problem. It would be great, if people could have a look at the routing debug layer in their area and start fixing the connectivity issues. One does have to be a little bit careful though, as there are a number of false positives. I.e. where roads end close to each other but truly aren't connected. E.g. because there is a wall between them. Most of the time one has a fairly good feeling though if it is a bug, or potentially isn't connected.
