Thanks Steve, very well said :-) I think my best course of action is to proceed in importing a VERY small test area of the canvec/NHN features that i know is good. And post the known bug of "duplicate intersecting nodes" (bug1)
I then will stretch my learning curve to learn python & make AutoMatch work for CanVec data. (bug2) Great work as always, cheers, Sam On 4/7/09, Steve Singer <[email protected]> wrote: > On Tue, 7 Apr 2009 [email protected] wrote: > >> You said you had these housenumber-data for the segments, not for the >> whole >> way, did you? >> >> Then there is no issue with curvy roads. > > Yes > >> Well, at least add your data to the way as canvec:housenr_left_start= >> and similar, so the data does not get lost. > > The source dataset from the government isn't likely to go anywhere so > I'm not too concerned about it getting lost. > >> >>> If we want to use a Karlsruhe scheme then this will need a script similar >>> to >>> what the ump2osm is doing, I think we are best waiting till someone >>> can do that with offsets and relations to the road (the complexity of the >> >>> script will probably be comparable to the ump2osm script). >> >> What language do you need it to be in? >> > > So far the import scripts I've been using are in python. > >> What data-model are you using for the osm-data >> (how can the scripe get the way? >> ...and the nodes for the way's waynodes? >> how can it output new osm-entities? >> how can it search an area if some osm-entities are already present?) >> > > For the geobase roads I am using a program called RoadMatcher that is a > plugin to JUMP for detecting roads in that are likely to already be in OSM. > I then import the geobase roads and tag each way with the uuid > (geobae:uuid) that mostly identifies the source road segment.
