OpenStreetMap

Anyone has a tool to fix this kind of way?

Posted by pieleric on 16 May 2013 in English (English)

There are quite a few ways in the database which are passing by several times the same point. Such an example: http://www.openstreetmap.org/browse/way/191420773

There are lot of those in this area, but I've such seen a ways a bit everywhere in the map. It seems like it's pretty easy to do with Potlatch, and really hard to fix :-/

Anyway, is there a tool to fix such a way? Or maybe someone has a tip on how to fix them easily?

Location: 35, Weyburn, Saskatchewan, Canada

And in the example also : layer=-5 ;-) I used to fix it in Potlatch. Mostly however I delete and remap it. If you try to solve it in Potlatch you end up with a lot of double ways, and it's hard to see that.

That's some really ugly stuff. By far the easiest thing to do is to delete and remap. I rarely use Potlatch, but even in JOSM fixing self-crossing roads like these tends to be really cumbersome.

Try splitting the way in JOSM: http://josm.openstreetmap.de/

Just select the road and the node at the T-intersection and press P. The bottom branch will separate and become a circular way. Now you’ll need to select both ends of this line, press P again and then delete one of the obtained overlapping ways.

Deleting the entire objects is something one should avoid. Apart from loosing their history there is a chance of breaking some urls. For instance, a number of Flickr images are tagged as osm:node=123 or osm:way=123, which links them directly to objects on the map.

Hope it helps!

There are many other thins to fix in your area, e.g. missing or detached nodes at the intersections or duplicate road segments:

Good luck!

The bot Wall·E fixes duplicated nodes in ways fully automatically (at least since 23th April 2013) in Germany and Austria, currently.

I would draw a new way, mark both new and messed up way and use "replace geometry" on this selection. Should be the easiest way to fix such a thing and keep the history, too.

I've been trying to fix up some of this mess, but there is a lot of it in Saskatchewan ... sigh
