It's in README.MAPS, right after where it describes how to run the ogr2ogr for the linear features, but what's there is pretty sparse. Each of the original TIGER/Line directories needs to be processed a second time using the "Xastir-tigerpoly.py" script to make the additional polygon shapefiles. That script requires gdal with python support, and can be found in the scripts directory of the xastir source code. I also recommend using the "-d" flag to dissolve boundaries between polygons with the same name, or things like parks and other major polygon features will generally be made up of many small, individually labeled polygons. When I first mapped out the process for doing the conversions I wrote a simple script that did the ogr2ogr and the Xastir-tigerpoly.py for each of the tiger files for a whole state, and extracted the county name from the ".MET" file to use as the file name. I think I still have that script lying around at work and can provide it here (it's very simple and never seemed significant enough to add to the scripts directory, and I was lazy and hardcoded some of the title parsing stuff in a way that had to be hand-edited for each state). I think Derrick Brashear did something a little more clever with it when he did the 2004 files to be placed on xastir.tamu.edu. > On 19 Feb 2007, at 21:15, Jason Winningham wrote: > > > > >On Feb 19, 2007, at 3:05 PM, Jason Winningham wrote: > > > >> (except for the missing polygons). > > > >I should clarify: the polygon data is generated via a different > >method, and results in a separate shapelib.
