And this is the last year that TIGER/Line data will be released in that format. According to their web site, they will start releasing the Census maps in shapefile format --- but from the looks of it, these shapefiles will NOT be very useful for the purpose of drawing road maps. The dbf fields they plan to include are very clearly designed solely for census purposes, and they will be missing a lot of the data that we rely on for rendering. > Lee Bengston wrote: > > On 10/5/07, Jason Winningham <[EMAIL PROTECTED]> wrote: > >> > >> On Oct 5, 2007, at 8:48 AM, I wrote: > >> > >>>> http://roadnav.sourceforge.net/ > >>> Ah, this is more like it.
