For government/bulk imports -where we know that updates are available; how is it dealt with? I was just thinking about this; there is a lot of MassGIS data now, and some of it is wrong (wrong location, streets that don't actually exist), although 99.8% of it seems very good. I've edited classification of highway, and added names. So I think this is really 3-way merge process, and there needs to be something that looks at each item in the new dump, finds any previous import, and checks if it has been modified. If not, apply the new change to the object, and if so, it's harder. That doesn't sound like what you are proposing, but I didn't quite follow. pgptmEnxok1HU.pgp Description: PGP signature ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I dunno about Iceland, but you're right about France, it is the official land registry map that we got access to.

Re: [OSM-talk] uStream .tv broadcast 2pm PST 5pm EST - geobase import
Thanks, ya your right :) The show went good (IMO) as the question is now more apparent. For government/bulk imports -where we know that updates are available; how is it dealt with? The solution is this IMO: 1- take the latest OSM Data, as a file; the exact size area of the shape file to be imported. 2 - extract only the possable tags (if any) that are showing the same info as you want to have the new data shown as. 3 -convert the OSM to shape file 4 - make a backup of OSM file 5 -remove those same selected osm data OUT OF the osm database. 6 - using whatever postGIS program, look at both shape files, and see just how the 2 match up. 7 add osm tags the the whole thing. 8 use one of the bug finder tools to find duplicate data, and PERGE all the info together. 9 the result is a file that contains; new imported data with osm tags, untouched osm data (that no match was available), and perged data (osm imported) 10 convert the file to OSM and upload to OSM. Please poke fun at the steps, :) cheers, Sam On 1/24/09, Thomas Wood grand.edgemas...@gmail.com wrote: 2009/1/24 Sam Vekemans acrosscanadatra...@gmail.com: In light of France getting the OK for post codes; Canada might also, so there needs to be a way to accomidate it.
