Thanks to Jennifer Holland from the Census Bureau for providing us easy links to the TAZ/TAD files. These paths require less "clicks" to access the files. In the TAZ directory you will find all of the state-based TAZ files for the nation and in the TAD directory you will find the national TAD file. The files names are the same as in my original message but this path requires less navigation through folders. The rest of the 2010 Census TIGER/Line Shapefiles, organized by type of geography, can also be found by using this path. The links are: ftp://ftp2.census.gov/geo/tiger/TIGER2010/TAZ/2010/ ftp://ftp2.census.gov/geo/tiger/TIGER2010/TAD/ Cambridge Systematics, Inc. 4800 Hampden Lane Suite 800 Bethesda, MD 20814 tel 301 347 9141 fax 301 347 0101 FHWA 202-366-6971 e-mail llong(a)camsys.com www.camsys.com From: Liang Long/wdc/camsys To: ctpp-news(a)chrispy.net Date: 04/17/2012 11:06 AM Subject: TAZs and TADs for CTPP 2006-2010 are available now! Although CTPP 2006-2010 will not be out until the year of 2013, but Traffic Analysis Zone (TAZ) and Traffic Analysis District (TAD) delineated for CTPP 2006-2010 are available now in the Census Bureau FTP site. Here is the link: For TAZ, go to this ftp site ftp://ftp2.census.gov/geo/pvs/tiger2010st/ [THEN PICK YOUR STATE Folder--you have to select the state-level directory twice. TAZ files are NOT under the county-level directory, only the state. The file name is tl_2011_XX_taz10.zip (where XX= State FIPS) For example, South Caroline TAZ files are in this directory: < ftp://ftp2.census.gov/geo/pvs/tiger2010st/45_South_Carolina/45/tl_2011_45_t… ftp://ftp2.census.gov/geo/pvs/tiger2010st/45_South_Carolina/45/tl_2011_45_t… TAD: ftp://ftp2.census.gov/geo/pvs/tiger2010st/ [SCROLL to BOTTOM] File name is: tl_2011_us_tad10.zip <ftp://ftp2.census.gov/geo/pvs/tiger2010st/tl_2011_us_tad10.zipftp://ftp2.census.gov/geo/pvs/tiger2010st/tl_2011_us_tad10.zip Feel free to contact me if you have any questions.
