2 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

3 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

4 Major Components of 2010 Census Address List Development

5 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

6 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

7 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

8 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

9 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

10 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:

11 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:

12 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

13 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.

14 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.

15 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!
