TRANSCRIPT
The Geographic Support System
Initiative
(GSS-I)
Update for the
State Data Center Steering Committee
June 14, 2012
1
What is the GSS-I?
• An integrated program of:
– Improved address coverage
– Continual spatial feature updates
– Enhanced quality assessment and measurement
– Improved partnerships
• Supports a targeted, rather than complete, Address
Canvassing operation in 2019
2
Address Improvement Goals
• Current and complete address coverage
– Partnership programs
– Commercial address list sources
• Expanded address sources for MAF update, especially
in areas without city-style addresses
• Development of guidelines for submission of address,
feature, and boundary data
• American Community Survey (ACS) and current surveys
need current and complete coverage
Feature Improvement Goals
• Ongoing street network and attribute updates
• Best available data from partners and commercial files
• Imagery for change detection and source evaluation
Quality Improvement 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
2: Assign Quality Indicators to
MAF/TIGER data
New incoming
data
New Tools
Partners
Enhanced Feedback
New and Enhanced Programs
TIGERweb

Volunteered Geographic
Information (VGI)
Enhanced collaboration
Expand Existing
Partnerships
Engage New
Partners
Utilize new tools
and programs to acquire
address and spatial data
in the most efficient and
least intrusive ways
Address Feedback
TBD, but adhering to
Title 13 confidentiality
laws

• The Steering Committee reviews and approves or rejects
WG Recommendations
• Approved WG Recommendations are prioritized
– 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
8
60+ WG Recommendations
FY 2012 and 2013 = Implementation
• Working Group Recommendations
• Integrated Project Teams (IPTs)
• Research Reports and Recommendations
• Address Summit Pilots

• 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)
• 5 Completed Reports
– http://www.census.gov/geo/www/gss/reports.html
• 2 In-Progress Reports
– Change Detection
– Master Address File (MAF) Evaluation
Continued Market Research
For Geospatial Information Sharing
• 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
• 3 companies responded to the RFI with viable
proposals

Address Pilots
14
• Federal/State/Tribal/Local Address Management
Coordination
• Data Sharing – Local/State/USPS/Census
• Address Authority Outreach and Support for Data
Sharing Efforts
• FGDC Address Standards and Implementation
• Hidden/Hard to Capture Addresses
15
Moving Forward These pilots will provide:
• The Census Bureau with a testing ground for future
geographic partnership programs
• The Census Bureau with an opportunity to identify the best
methods for the continual update of the MAF/TIGER
System

2020 Research and Testing Teams
• Participating on ten 2020 Research and Testing Teams
and several sub-teams
• Greatest involvement:
– MAF Error Model/Independent MAF Quality
Assessment
– LUCA Program Improvement
– Field Automation
• Corporate Listing Device
