I have done some work today, I hacked the osm2poly to produce polygons from the tiger 5 point zip codes : http://fmtyewtk.blogspot.com/2009/12/using-osmosis-to-split-zipcode-files.html
It produces one polygon file per zipcode tabulation area. I can then extract the data from that to look at what fits in it. Also, you can see from my older posts, I setup qgis and was able to pull in the various zipcode layers and admin borders. Will be producing polygons for the counties as well, easy stuff. The next scripting job will be to create relationships from the ways, and reuse the sides of the boundries. I am reviewing my old zipcode 07933 now and resolving some obvious problems with the tiger zip codes which are very wildly distributed. You can use these zipcode boundaries as a starting point for checking the consistency of the data. mike On Mon, Dec 21, 2009 at 3:50 PM, David Fawcett <david.fawc...@gmail.com> wrote: > An interesting article about the recent increase in the rate of change > in zip code boundaries: > http://www10.giscafe.com/nbc/articles/view_weekly.php?articleid=763562&page_no=1 > > David. > > _______________________________________________ > Talk-us mailing list > Talk-us@openstreetmap.org > http://lists.openstreetmap.org/listinfo/talk-us > _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
