Re: [Talk-us] [Imports] Importing Virginia road centerlines
Josh, Are you on the regular talk list? There's been a long discussion about the dangers of importing on that list. Since you're new to importing, I'd suggest reading that thread so you're familiar with the pitfalls. Where in Virginia are you? If you're near the DC area, a few of us have been planning on meeting in the near future to discuss DC and its import issues (good and bad) and so this seems like it'd fit right in. Lastly, is your data available somewhere others can look at it? I'd like to just make a simple, quick comparison map with it. - Serge ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
Re: [Talk-us] [Imports] Importing Virginia road centerlines
Serge, I am, and am aware there are dangers, though I'm sure I'm not aware of all of them, which is why I'm going slowly. :) I'm in Fairfax County, so it would be good for me to attend that meeting. I've linked to the data on the wiki (Virginia [1] and Fairfax County [2]). Please let me know what you find, as I'm still learning the tools to work with Shapefiles and osm.

Hi, Katie Filbert wrote: How about just converting the data to OSM format. Break it up by small, manageable chunks such as census tracts. Post the files somewhere. Maybe OSM-US can help provide a place for them. I hear that Potlatch2 already has a mode where you can load a shape file as a background layer, and copy geometries (one by one) onto the OSM layer. I haven't used that myself, but on the whole this sounds like a sensible mode of operation. I think it doesn't to attribute conversion yet but that would be a simple matter of programming for someone with the necessary skills. What I like most about it is that you have a forced visual feedback - there is no way you can copy something into OSM without seeing what is actually there before you do. Then allow local people to do the imports, using JOSM. That is possible, but carries with it the danger of over-eager people doing blanket imports again...

The thing I like about Potlatch is that the mapper must (!) copy each element individually. This is of course much more work than simply dumping a shape file into OSM, but I'm convinced that such diligence shows in the result, and also increases the attachment of the mapper to his work, leading to more involvement with the project etc. (Of course that's still nothing against going out there and surveying by yourself.) If you drive along a road and say: That name sounds familiar, I think I have imported that - then that may just have been an acceptable import.

Re: [Talk-us] [Imports] Importing Virginia road centerlines
Josh, I like Katie's idea of breaking the data up into manageable chunks (counties?) and importing in incrementally. I'd be interested in helping with a few chunks. I'm in Arlington, too. Perhaps we'll meet at a DC area event?
