I've been adding lakes and ponds to New York State. I have a list of points and names[1]. I'm using the lat/lon to point me to a lake/pond which is in this list. I trace it using bing aerials, and look at the (public domain) USGS topographic maps to add the name. I'm making good progress. It's taken me since August of last year, and I'm now into the S names. It's fun! For a small pond or lake, it takes less than 30 seconds to add it. So, what if we could automatically identify misaligned TIGER ways and make a list? Then people could take a few minutes, grab a few ways and armchair fix them. I've been working on finding and fixing them in New York State. I've probably got more than half -- maybe 60% fixed. Hopefully even 70%. And I'm just one mapper (well, and you're another mapper who's done a ton, plus there's a few more I'm sure). My main difficulty right now is finding areas of misalignment. I've gone through entire counties and aligned every road I could find, but I'm sure I missed a few. It doesn't have to be a perfect process; it just needs to be easy and quick to use. It's okay if a few already-fixed roads get pointed to, as long as it's not too many, and it's okay if a few unfixed roads get skipped, as long as it's not too many. The better we can make the map data, the more people will want to use it to make maps and the more people will want to fix That One Last Flaw. [1] I'm not sure of the copyright license on the list, so I'm using it to point me to the general area of a lake or pond, and digitizing it de novo. -- --my blog is at http://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
