2009 TIGER/Line Shapefiles released today; info on 2010,TIGER/LineShapefiles

by Ed Christopher

FYI--Besides the 2009 Tiger Files it looks like we will have the new 2010 Files before the 2010 Block population counts come out in around March of 2011. This is good news. Just yesterday I was in a meeting where the question came up. ================== The Census Bureau has released 2009 TIGER/Line Shapefiles today. Available here: http://www.census.gov/geo/www/tiger/ This will be the last public release of TIGER data until early 2011. This early 2011 release will include all of the updated 2010 tabulation geography that serves as the geographic framework for 2010 Census data tabulations (including the new 2010 Census tracts, block groups, blocks, voting districts, and much more). Around the same time as this 2011 geospatial data release, Census will be releasing the tabular data with 2010 Census population counts down to the Census block level. See the attached document for more information, including changes under consideration and a request for input. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443

Fwd: RE: ansi v fips

by Nathan Erlbaum

I thought that the information noted below would be of interest to those who follow this list serve and are interested in geographic referencing for use with census products Here is information from the Census Bureau's website on these codes: American National Standards Institute codes (ANSI codes) are a standardized set of numeric or alphabetic codes issued by the American National Standards Institute (ANSI) to ensure uniform identification of geographic entities through all federal government agencies. These standards replace the Federal Information Processing Standards (FIPS) codes previously issued by the National Institute of Standards and Technology (NIST). The entities covered include: states and statistically equivalent entities, counties and statistically equivalent entities, named populated and related location entities (such as, places and county subdivisions), and American Indian and Alaska Native areas. ANSI maintains an Internet World Wide Web site of ANSI codes and information<http://www.ansi.org/default.aspx> [cid:image001.gif@01CAF5CA.DECEE3A0] . ANSI publications include: INCITS 38:200x<http://www.census.gov/geo/www/ansi/statetables.html>, (Formerly FIPS 5-2) Codes for the Identification of the States, the District of Columbia, Puerto Rico, and the Insular Areas of the United States INCITS 31:200x<http://www.census.gov/geo/www/ansi/countylookup.html>, (Formerly FIPS 6-4) Codes for the Identification of Counties and Equivalent Entities of the United States, its Possessions, and Insular Areas INCITS 454:200x<http://www.census.gov/population/www/metroareas/metrodef.html>, (Formerly FIPS 8-6) Codes for the Identification of Metropolitan and Micropolitan Statistical Areas and Related Areas of the United States and Puerto Rico INCITS 455:200x<http://www.census.gov/geo/www/cd110th/main110th.html>, (Formerly FIPS 9-1) Codes for the Identification of Congressional Districts of the United States INCITS 446-2008<http://geonames.usgs.gov/domestic/index.html>, (Geographic Names Information System (GNIS)) Codes for Named Populated Places, Primary County Divisions, and Other Locational Entities of the United States, Puerto Rico, and the Outlying Areas.

Urban Area Webinar

by Ed Christopher

Where are we with Urbanized Areas? On Friday June 11, 2010 Federal Highway Administration in coordination with the Census Transportation Planning Products program will host a two hour webinar on the Census Bureau’s plans for defining new Urban Areas. These areas are important for transportation planning because of requirements for establishing MPOs and revisions to MPO boundaries, TMA designations, and roadway functional classification. This webinar is a follow on for those who could not attend a similar workshop held at the GIS-T Conference in West Virginia. In addition to discussing Urban Area boundary development, Census Bureau staff will discuss several other geographic related products and programs. Every 10 years following the decennial census the Census Bureau redefines Urban Areas. Urban Areas include both Urbanized Areas and Urban Clusters. This webinar will begin promptly at 1:00 PM (Eastern) and run for 2 hours. It will include presentations along with time for question and answers. Topics covered will include: • A Brief Transportation Perspective on Census Geography, Ed Christopher (FHWA) • Discussion of the Proposed Urbanized Area Criteria, Mike Ratcliffe, Census Bureau Geography • Review of Census Geographic Area Programs and Products, Mike Ratcliffe, Census Bureau Space is limited and advanced preregistration is necessary. If you are unsure that you will attend please do not register. If more than one person from a site can share one computer connection that will help make space for others. The webinar will be recorded for those who miss it. To register go here and complete the form. http://www.nhi.fhwa.dot.gov/resources/webconference/web_conf_learner_reg.as… If you have difficulty registering or have any question please let me (Ed Christopher) know edc(a)berwyned.com or 708-283-3534. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443
