Presumably not. Potlatch loads shapefiles into a separate layer and requires mappers to manually pull the data into OSM. > Also, is this something that works only in JOSM, in which > case many of us couldn't use it? No. For one thing, Richard is the main developer of Potlatch and doesn't do anything with JOSM. For another thing, he mentioned "reworking the P2 source code"; "P2" refers to Potlatch 2. > Also, I still don't understand why all the TIGER data was > deleted on ways that were partially deleted. Because of OpenStreetMap's data model. When you split a way, what your editor does is upload a changed version of the original that only contains half the original nodes and then upload a new way with the same tags as the old one that contains the other half of the nodes. To subsequent database queries, the second way appears as though you created it and there's no direct link back to the way that originally contained the nodes. On top of that, there was a deliberate decision made (as I understand things) not to undo deletions, which includes the removal of nodes from a way. Had the bot done that, there would be many places where the bot would create multiple, overlapping, tangled ways. Since either approach would have left significant messes for mappers to clean up, there wasn't really a good way forward. The people working on the redaction bot felt that not undeleting would be the better of two bad options. -- ...computer contrarian of the first order... / http://aperiodic.net/phil/ PGP: 026A27F2 print: D200 5BDB FC4B B24A 9248 9F7A 4322 2D22 026A 27F2 --- -- i am not interested in a penis for aesthetic purposes. -- isabelle whitman ---- --- -- _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
