Geographic Support System Initiative Indiana GIS Conference May 9, 2012 Gail A. Krmenec US Census Bureau Chicago Regional Office Stanley D. Moore Regional Director
2010 Census – MAF/TIGER Enhancement Program including MAF/TIGER Realignment (7.6 meter min. accuracy) Census Geographic Support – Major Initiatives Over Time
What is the GSS-I? • Improved address coverage • Continual address and spatial database updates • Enhanced quality assessment and measurement • Improved Partnerships
Why the GSS Initiative? • Recommendations of our stakeholder and oversight communities (GAO, OIG, NAS): • Lack of a comprehensive geographic update program between censuses • Associated negative impact on ongoing programs such as the American Community Survey, other current surveys, and small areas estimates programs • Supports a targeted Address Canvassing for 2020 Census 2015
Full Address Canvassing is VERYexpensive: • Addresses to be verified: 145 million • Census workers hired: 140,000 • Hand-held computers: 151,000 • Local Census Offices managing operations: 151 • Operational Dates: March 30 - July 2009
Why “Targeted” Address Canvassing? Goal: develop on-going update and change detection processes Target only areas with uncertainty Quality of Addresses Currency of Addresses • Hinges on establishing an acceptable address list for each level of government
GSS-I Goal:Address Coverage • Complete and current address coverage • Additional emphasis on change detection • Expanded address sources for MAF update, especially in areas without city-style addresses • American Community Survey (ACS) and current surveys need current and complete coverage 123 Testdata Road Anytown, CA 94939 Lat 37 degrees, 9.6 minutes N Lon 119 degrees, 45.1 minutes W
GSS-I Goal:Feature Coverage Ongoing street network and attribute updates Best available data from partners and commercial files Imagery for change detection and source evaluation Increased BAS (Boundary & Annexation Survey) participation
GSS-I Goal: Quality Assurance Goals 1: Establish quantitative measures of address and spatial data quality 2: Assign Quality Indicators to MAF/TIGER data
GSS-I Goal: Improved Partnerships New Tools Partners Volunteered Geographic Information (VGI) Web-based Address Management Tools Data upload systems TIGERweb Enhanced collaboration Expand Existing Partnerships Engage New Partners New and Enhanced Programs Enhanced Feedback Build on and Expand MTAIP Feedback for Spatial Features Address Feedback TBD, but adhering to Title 13 confidentiality laws Utilize new tools and programs to acquire address and spatial data in the most efficient and least intrusive ways
Who are the stakeholders? • US Census Bureau • Other federal agencies (USPS, USGS, EPA) • Tribal, State, County, and Local governments • Commercial data providers • National Advocacy Groups, such as NSGIC, URISA, NENA, and NAPSG • YOU
What’s in it for you? • Improved address and feature coverage (local govts are authoritative source) support current survey samples, including the American Community Survey • More current data and improved process flows should minimize the impact of programs like LUCA • Taxpayer savings (targeted ADCAN) • Accurate 2020 Census • Our evaluations & feedback may help you improve your data
GSS-I Timeline FY ‘11: Address Summit Pilot Proposal 1: Federal/State/Tribal/Local Address Management Coordination Pilot Proposal 2: Data Sharing - Local, State, USPS, and Census Pilot Proposal 3: Address Authority Outreach and Support for Data Sharing Efforts Pilot Proposal 4: Web Based Management Tools Pilot Proposal 5: FGDC Address Standards and Implementation Pilot Proposal 6: Capture of Hidden/Hard to Capture Addresses FY ‘12: Process Development FYs ‘13-’20: Change detection Completeness/coverage testing Updates to the MAF/TIGER System
Minimum Address Guidelines http://www.census.gov/geo/www/gss/gdlns/addgdln.html
Minimum Address Assumptions Sample rules for acceptable addresses: • All required fields must have data Address Number, Street Name, and ZIP Code OR Tract/Block OR City/State • Must meet predefined business rules Ex: ZIP Code is numeric, five digits • If two or more addresses have the same house number, street name and ZIP, then one of them must have an additional address element (i.e., unit designator, such as Apt 101)
Address Metadata • In addition to the standard FGDC Address Standard metadata, we would like to collect: • What is the source of the address (assessor, utility, emergency management)? • Is the address used for mailing and/or locating the structure? • Is the address for a Group Quarters (prison, college dorm)? • What type of structure does the address represent (single-family home, trailer, multi-unit apartment building)? • Is it a commercial, residential, or other type of address? • When was the house built and/or addressed?

County Consolidated BASBoundary & Annexation Survey • BAS: January 1st of each year • Many entities still participating on paper boundaries, relatively correct • (Most) counties can participate digitally • Have you reviewed the boundaries for accuracy? (MTAIP Realignment!) 2013 C-BAS sign-up deadline: 8/1/12
