Re: [Talk-us] Temporarily Deleting Relations from Interstate Ways
not a good idea to delete the relation. It will be incredible painful to add all pieces agin and not missing a single bridge. Josm is the best solution. Also Merkaator supports Yahoo images. The nice thing in Josm is you can select all members of a realtion easily. download all members, for windows there is a single download for webkit. Mac OS is a bit more work but works too.

For simple stuff like this it is pretty easy to use. If you have a specific gripe against JOSM, let me know -- I'd be happy to help you work through it. If you just don't like it, I don't think there are any other editors out there that are as feature-complete as Potlatch or JOSM. Also, I vote that you don't remove relations just to make editing easier. It would be a pain to add those back. Is there a wiki page on how to get the Yahoo imagery into JOSM painlessly? That's the primary reason I used Potlatch when fixing up bits of I-80/81 around here. -Ted ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

When I load OSM data for Tucson, Arizona then it is off by perhaps 100ft. I would like to make the maps for Tucson usable, so my questions are: - how do I tell where this problem begins and ends? You probably can't do this on a large scale. - how do I fix it? In JOSM, you can select and move large numbers of objects at once. My neighborhood was off by a couple hundred meters. I went and fixed it all back up manually. I don't have the time to manually move everything, so there must be some kind of automated solution? Does this problem exist for the whole of the US? Is it well understood? No, it doesn't exist for the whole US. It is well understood. TIGER is a collection of data from many, many sources. Some of these were from local governments that were themselves aggregating data from multiple sources. Sometimes, the data were off from one of these sources. It was not collected for the sole purpose of mapping, so nobody really cared. Also if you look at the diagonal (NW-SE) part of the Arizona-Mexico border there are streets in the US that appear in Mexico - the whole border area appears to be a mess. How do I know what needs to be done to fix this? The error looks larger than 100ft. You really need some good GPS traces of the streets, or you can try to align it on yahoo imagery. -- Dave ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

I would like to make the maps for Tucson usable, so my questions are: - how do I tell where this problem begins and ends? Get on the road, create a trace of where you want to check. Visually compare map to trace. - how do I fix it? JOSM usually works well. I don't have the time to manually move everything, so there must be some kind of automated solution? Does this problem exist for the whole of the US? Is it well understood? No automated solution. Problem exists to varying degrees nationwide. It's well understood that the TIGER data has a giant margin of error. Also if you look at the diagonal (NW-SE) part of the Arizona-Mexico border there are streets in the US that appear in Mexico - the whole border area appears to be a mess. How do I know what needs to be done to fix this? The error looks larger than 100ft. This will probably require some serious manual intervention. If you know where the border really is in that area, you should probably fix it. signature.asc Description: OpenPGP digital signature ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
