For MAPPS; March 27, 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 (MAF)
Census Geographic Support –
Major Initiatives Over Time
For the 1990 Census – Introduced TIGER
2
Why the GSS Initiative? • A logical next step, building upon:
• Accomplishments of the MAF/TIGER Enhancement
Program (MTEP)
• MAF/TIGER Accuracy Improvement Project (MTAIP)
• Improved positional accuracy of TIGER
• Contributions of our partners
• GIS files & imagery between 2003 to 2008 for MTAIP
• 2010 Local Update of Census Addresses (LUCA)
Program
• The recommendations of our stakeholder and oversight
communities
• Supports a targeted Address Canvassing in
preparation for the 2020 Census
3
Why the GSS Initiative?
• Stakeholder and oversight recommendations:
– The General Accountability Office, the Office of the Inspector General, and the National Academies of Science identified as issues:
• The 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
4
Key Components
• An integrated program that utilizes
partnerships for:
– Improved address coverage
– Continual address and spatial feature updates
– Enhanced quality assessment and measurement

41 Submitted Recommendations
• The Steering Committee reviews and approves or rejects WG Recommendations
– The majority (too many for immediate implementation) have been approved
• Approved WG Recommendations are prioritized
– High (immediate implementation), medium, & low
– Recommendations are deemed high priority if they are determined to be essential to the 2015 targeted Address Canvassing decision, or
– Directly contribute to achieving the GSS Initiative goals, and
• Support the exchange of data and use of partnership files, or
• Provide standards, quantify/track quality
• Formation of Integrated Project Teams (IPTs)
– IPTs champion the immediate implementation of approved, high priority Recommendations
10
FY2012 = Implementation What are we doing with 41 WG Recommendations?
• Integrated Project Teams (IPTs) manage Recommendation implementation
• Identify resource needs
• If hardware and/or software development is required
– Determine Buy-or-Build
– Manage interface/integration with existing hardware/software
– Identify future maintenance needs
• Develop the project
– Schedule
– Dependencies
– Assumptions and Expectations
– Risk Register
– Communication Plan
– Architecture, Customer Requirements Document or Software Requirements Specification, as applicable
– Ensure adherence to Change Management
– Keep senior managers informed of progress/problems

FY2012 High Priority
Recommendations • Identify and resolve existing MAF/TIGER Database
(MTDB) data deficiencies
• Identify geographic areas requiring spatial updates or with “irregular” linear features in order to prioritize building partnerships and obtaining GIS files
• Resolve “ungeocoded” addresses
• Identify high level indicators for assessing MTDB quality
• Improve spatial feature metadata
• Provide a method of producing, recording, and reporting quality rankings for geographic areas continuously over time as updates occur (longitudinal analysis)
13
FY2012 = Contracting For GPS Point Collection
14
• Last decade Geography Division contracted for the
collection of 110 GPS points per county to determine
the positional accuracy of proposed source data for
MTDB feature realignment – Points were randomly selected MTDB road intersections
• This decade, Geography Division once again will
contract for GPS points – 800 counties still lack GPS points
– Some collections were in “multi-county” area; plan to fill in these
areas
– Control points will be used to prove in the positional accuracy of
imagery, which will then be used to validate feature updates (new
intersections) being added to the MTDB
FY2012 = Continued Market Research For Geospatial Information Sharing
15
• The Census Bureau issued an RFI for a
collaborative partnership activity focused on
geospatial information sharing
• The GSS Initiative proposes continual feature
updates via intake of data; the RFI is a proof of
concept
• We will be working with the 3 companies that
responded to the RFI with viable proposals
FY2012 = Implementation Continued Input from Outside Experts
16
• 4 Outside Experts – Stephen Guptill, Ph.D. (US Geological Survey, Retired)
– David Cowen, Ph.D. (Professor Emeritus, University of South Carolina)
– Michael Dobson, Ph.D. (Chief Cartographer Rand McNally & Co, Retired; TeleMapics, LLC, President)
– John Jensen, Ph.D. (Professor, University of South Carolina)
• 2 Reports – Change Detection
• An review of the Geography Division’s in-house change detection capability (for features reliance on USDA National Agriculture Imagery Program orthoimagery) and investigation of other potential sources of remote sensor data, more automated methods of extracting accurate change information, and whether the change detection should be performed in-house, by outside contractors, or a hybrid approach. Report + recommendations deliverable August, 2012
– Master Address File (MAF) Evaluation
• A description and analysis of the content that comprises the MAF, an analysis of how useful the data in the MAF have been in creating viable address products, and potential methods for improving the MAF. Report + recommendations deliverable August, 2012
FY2012 = Implementation Partnerships – Address Pilots
17
• Geography Division hosted an “Address Summit”
– in September 2011
• Results include Address Pilot Projects
– Federal/State/Tribal/Local Address Management Coordination
• To create a formalized model to allow for the development, maintenance, and bi-directional (state-local-tribal and state-federal) sharing of high quality, multiple use, address data
– Data Sharing – Local/State/USPS/Census
• Create a model that will allow for address data sharing between local governments, state governments, the USPS, and the Census Bureau
– Address Authority Outreach and Support for Data Sharing Efforts
• To research and develop an approach for identifying and creating an inventory of address authorities which facilitates the continual update of address data sharing activities, and provides guidance on overcoming barriers (legal/policy) at the local level
– FGDC Address Standards and Implementation
• To educate local authorities on the benefits, use, and implementation of the Federal Geographic Data Committee’s United States Thoroughfare, Landmark, and Postal Address Data Standard (FGDC Address Standard)
– Hidden/Hard to Capture Address Pilot
• To educate local authorities on the benefits, use, and implementation of the Federal Geographic Data Committee’s United States Thoroughfare, Landmark, and Postal Address Data Standard (FGDC Address Standard)
18
FY2012 = Implementation Other Activities
19
• TIGERweb – a publically available service
– TIGERweb Viewer is a new web-based tool that allows users to visualize
Census geography • The geographic data includes legal and statistical geography as well as the roads, railroads,
and water layers in the TIGER database.
• Contains the 2010 Census population and housing unit counts for the various geographic
entities
– The TIGERweb Viewer is built
on ArcGIS Template Viewer
2.2 using Microsoft Silverlight.
– Users can access the “how to”
video on the introductory web
page
http://tigerweb.geo.census.gov
FY2012 = Implementation Other Activities
20
• On the (Near? Far?) Horizon
– We are investigating improved conflation (overcoming the difficulties
of ingesting data to a topological database) – internal development
coupled with the user of vendor technology?
– WG Recommendations for
• Developing a secure, web-based data exchange system
• Utilizing Crowd Sourcing as one TIGER update avenue
• A methodology for receiving Volunteered Geographic Information (VGI)
FY2012 and Beyond Future, Continued Funding?
21
• The GSS Initiative is funded as part of Geographic Support
• The GSS Initiative is a 10-year life cycle program
• Though “preparatory” work begin in FY2011, actual funding
began in FY2012
• There is an FY2013 funding reduction proposal that impact
the GSS Initiative
