[Talk-us] Fixing Alignments in JOSM
I'm not sure if I can clearly explain my problem, but I'll try. The tiger street alignments are a mess in my area and I'm trying to fix them. I will come across a situation where there is a North-South way that crosses an East-West way. Thet are joined with a common node. However in reality it is a staggered junction. So I need to split the North-South way into two pieces and it intersects the East-West way in two places. I cannot figure out how to do this in JOSM. I've tried everything - splitting a way at nodes, ungluing, etc. The way always remains joined. Can someone please give me a step by step guide to fixing this alignment problem? I hope I explained it clearly enough. Thanks, Andy -- Andy PGP Key ID: 0xDC1B5864 ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Can someone please give me a step by step guide to fixing this alignment problem? Sounds like a fun intersection. :) Could you give us some coordinates for it? I'll go take a look and see if I can explain what best to do. -- Dave ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

not sure if I understand correct. by staggered do you mean they are on different levels via bridges or underpass? then there is no need to split. instead 1) unglue the node, you will have 2 nodes at exact same location. one belongs to way one the other to way 2 2) if need to move: both are selected after unglue and will move together. you need to select one only. otherwise a move seems like they are still joined. 3) split ways and add tunnel,bridge,layer tags as needed. in general split, unglue works like this split can be done on any node of a way except start/end unglue can be done on any node shared by 2 ways.

Dave, That worked. Perfect! Thanks, Andy Dave Hansen wrote: On Tue, 2009-06-23 at 12:35 -0700, Andrew Ayre wrote: They are on the same level. The north-south alignment of the street was changed at an intersection. Here is a screen shot: http://files.britishideas.com/public/mapping/staggered.jpg I'd probably: 1. Take Sahuara's way and make a new node near its intersection with 5th 2. Split the way at both the new node and the existing 5th and Sahuara node, making 3 ways. 3. Delete the short way that connects the south Sahuara with 5th 4. Take the now dangling Sahuara and drag its end node over to the proper place on 5th and join the Sahuara end node with 5th. You'll end up with 2 ways where there used to be one, but that's OK. Is that what you were asking? -- Dave -- Andy PGP Key ID: 0xDC1B5864 ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
