I feel like I should explain here. I was experimenting with different ways to do the import. I found roadmatcher to be fairly painful to use (perhaps I was being too picky) in urban areas. So I generated a file with everything from the NRN in it for the area I was interested in. I then, in JOSM, found areas with roads missing, copied them out of the geobase layer, and into the osm layer. I connected up all of the roads, and uploaded. It was an easy approach, because I was working with an area that had the major roads in place, but all of the residential streets missing. So you could just pick a large blank area, paste in all of the data, and then connect it up on the edges. Much easier in my mind, because you can do it in small batches, an hour at a time (and you don't have to go in later and connecte everything up all at once). > However, this .osm file isn't redely available, nor was it posted on the > wiki chart as a direct download link. It's not posted on the wiki chart, because I didn't think to do so, but the file is available to anyone who wants it. http://drop.io/lxjbbxx is where they're at. > So, on the one-hand, i can just wait and i'll see the whole area mapped > (even though i know that i can copy it and get it just as accurate as > someone else can tracing over yahoo or their own GPS tracks. > > ...

And use RoadMatcher whever possable. I can certainly run roadmatcher to generate the normal file, but it's not really hard to do a visual diff in josm to see what areas are different. Of course, a computer's going to be more thorough, and not accidentally miss or duplicate things. I'm not sure that a mapping party is the best way to go about it (though getting all/most of the victoria mappers together would be good). Providing a file to everyone, along with decent instructions on how to use it would be nice... but then, I suppose that most people are using Potlatch (so scratch that idea, inflicting the learning curve of JOSM on someone isn't kind -- I like it now, but...) I think we can do it distributedly, but maybe this is just my bias because I find it hard to get together with other people. Ok, this message is long enough. I'll stop now :) 'night Austin. -- Build a man fire, he'll be warm for a day.
