Re: [talk-au] Routing "islands"
Yes Stephen, I quite agree. I would not want decisions like that taken away from the end user. But maybe the warning should point out that in most cases, a junction node is required. I know that now but seems there is no easy way for a new comer to find out. (I have been submitting tracks for several years.) Maybe I'll have a play with the wiki Anyway, that "keep right" website highlighted my errors from way back, and a heap of others, its a pretty useful tool. I have fixed a few and will keep at the ones I know about.

They might not actually join. There's a couple of examples near me where roads end less than a meter away from another road, but don't join up. Service roads, minor suburban streets and main streets where they used to join, but the main road has so much traffic now they've cut the connection, and a case where two new subdivisions had a road that was supposed to join, but the first guy stopped about a half meter short of the line, and the second one wouldn't pay the extra, so there's a tiny gap between the roads, and a curb. Also, you might have been working on some other portion of the road, and not near where the error is. Just last week I fixed some stuff at one end of a road, and when I went to save it, it warned of errors at the other end, but I can't do anything about them until I go down there and see what the problem is.

I am well on the way to fixing Canberra but the number of errors was/is amazing. I'm just about to do the floating Islands (orange in keep right). I've been giving you a bit of a hand there, but mainly outside Canberra. I apologise for not marking things I've fixed as "ignore temporarily (error corrected)". That's because I thought that flag was stored on my own PC, and not visible to all. Many intersections in Cootamundra had no connecting node. These are among the things I've fixed, although that problem was obviously pre-redaction. John ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

[talk-au] Routing "islands"
Hi. I noticed this the other day: Geofabrik Tools has a Routing layer that highlights "islands". Islands are ways that you cannot route to, and generally point to a problem somewhere. The routing layer only seems to apply to Europe, and puts hashing over the rest of the world, although the pink "Islands" overlay does work for Australia. e.g. See this section of Sydney: http://tools.geofabrik.de/osmi/?view=routing&lon=151.08138&lat=-33.86157&zoom=15 This shows a section of the M4 that could not be reached. It was due to a bridge incorrectly marked as being the wrong way. (Now fixed.) Here's another one that is not fixed yet: http://tools.geofabrik.de/osmi/?view=routing&lon=150.82846&lat=-33.75053&zoom=15 I haven't looked into that one yet, but I suspect one end of the road (or both ends) is not connected to the surrounding streets. It's quite a useful tool. - Ben Kelley. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
