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

• 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

60+ WG Recommendations

FY 2012 and 2013 = Implementation

• Working Group Recommendations

• Integrated Project Teams (IPTs)

– 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
