The Geographic Support System Initiative (GSS-I) Partnership Program Donna Bullock U.S. Census Bureau November 2, 2012
For the 2020 Census – The GSS Initiative For the 2010 Census – conducted the MAF/TIGER Enhancement Program For the 2000 Census – Introduced the Master Address File Census Geographic Support – Major Initiatives Over Time For the 1990 Census – Introduced TIGER
What is the GSS Initiative? Quality Measurement Street/Feature Updates Address Updates 123 Testdata Road Anytown, CA Lat 37 degrees, 9.6 minutes N Lon 119 degrees, 45.1 minutes W An integrated program consisting of: Improved address coverage Ongoing address and spatial database updates Enhanced quality assessment and measurement
Major Components of 2010 Census Address List Development
2010 Address Canvassing Facts Number of housing unit addresses that needed verification: 145 million Number of census workers hired for Address Canvassing: 140,000 Number of hand-held computers used: 151,000 Number of local census offices that managed operations: 151 Dates of operation: March 30 - Mid-July 2009
Goal: A Shift in Focus for the 2020 Census From a complete Address Canvassing to a targeted Address Canvassing –Hinges on establishing an acceptable address list for each level of government 6
Why a “Targeted” Address Canvassing? $$$! It is VERY expensive –Field an ARMY of address canvassers –“Walk” EVERY street in the nation… Goal: developing regular update and change detection processes Result: “Target” only areas with uncertainty –Quality of Addresses –Currency of Addresses
Quality Assurance Goals 3: Monitor and Improve the quality of the: Existing MAF/TIGER Data IT processes for updating the MTDB Geographic products output from the MTDB 1: Establish quantitative measures of address and spatial data quality 1: Establish quantitative measures of address and spatial data quality 2: Assign Quality Indicators to MAF/TIGER data 2: Assign Quality Indicators to MAF/TIGER data
Partnerships are Key! Local governments are the authoritative sources for address and spatial data! Expanding our Partnerships is Critical –Key step towards establishing an accurate and up-to- date address list The GSS-I Partnership Program seeks government, organizational, and commercial partners willing to share high-quality data on: –Addresses –Housing Unit Structures –Street Centerlines and Attributes
What Kind of Address Data? City-style addresses and/or Non city-style addresses (i.e., Rural Route #) that “ideally” meet: 1.USPS minimum delivery requirements, and 2.The FGDC Address Standard (U.S. Thoroughfare, Landmark, and Postal Address Data Standard) See the Draft Census Bureau Address Data Content Guidelines:
What Kind of Housing Unit Structure Data? Latitude/Longitude Coordinates for a Housing Unit structure or access point (i.e., from E-911 or Next-Gen E-911 database) Structure centroids Latitude/Longitude Coordinates for a real property parcel or parcel centroid Other points used by partner? See the Draft Census Bureau Address Data Content Guidelines:
What Kind of Street Feature Data? Street centerline geometry Street attributes – names, address ranges, etc. Why? Expand Census centerline and attribute coverage Spatially-correct misaligned streets in conjunction with high-quality imagery See also the Draft Census Bureau Feature Data and Metadata Content Guidelines: hhttp://www.census.gov/geo/www/gss/gdlns/addgdln.html
GSS-I Progress in last year Pilot projects from Address Summit (Sept. 2011) Address Authority Outreach and Data Sharing FGDC Address Standards and Implementation Federal/State/Tribal/Local Address Coordination Data Sharing Model– Local/State/USPS/Census Hidden/Hard to Capture Addresses Researched/acquired “test” county data for development of GSS-I processing systems. In AL: Bullock and Shelby.
Community TIGER New tool being developed in partnership with ESRI. Web-based data sharing/upload system. Open for all to use; no software license requirements. Input of state/local/tribal data produces standardized output format used to update MAF/TIGER. Beta version due in Feb 2013.
Planned Schedule Fiscal Year 2012 (Oct 2011 – Sept 2012) –Process Development, pilot work, research, system development, initiated Community TIGER October 2012 –Kickoff GSS Partnership Program (~51 partners, TBD) February 2013 –Start Providing Feedback to Partners March 2013 –Identify supplemental FY13 partners based on quality audit of MAF/TIGER data –Community TIGER beta testing October 2013 –Planning for open participation!
