What is 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

Lat 37 degrees, 9.6 minutes NLon 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

‘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

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

Goal: A Shift in Focus for the 2020 Census

• From a complete Address Canvassing to a targeted Address Canvassing

– Requires establishing an acceptable address list for each level of government

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– Evaluation may occur at the Census Tract level

Address improvement: explore methodologies to achieve complete coverage and a current address list

Feature improvement: ongoing update of the street network and attributes to improve the matching of addresses to their correct geography

Quality improvement: broaden quality assessments and provide quantitative measures

Improved Partnerships: strengthen existing and develop new partnerships

Goals of the GSS Initiative

GSS-I Address Coverage Goals

Complete and current address coverage

Achieve timely updates to meet currency needs of the American Community Survey (ACS) and current surveys

Additional emphasis on change detection

Expanded address sources for MAF update, especially in areas without city-style addresses

Simplify data sharing and minimize impact on local partners

GSS-I Feature Coverage Goals

Ongoing street network and attribute updates

Best available data from partners and commercial

Imagery for change detection and source evaluation

Quality Assurance Goals

3: Monitor and Improve the quality

of the:

Existing MAF/TIGER

Data

Who are the stakeholders?

• U.S. Census Bureau • Other federal agencies (U.S. Postal Service,

U.S. Geological Survey, Environmental Protection Agency)

• Tribal, State, County, and Local governments• Commercial data providers• National Advocacy Groups, such as NSGIC,

URISA, NENA, and NAPSG• YOU!

Partnerships are Key!

• Identifying authoritative sources for address and spatial data at various levels of government

• Expanding our Partnerships is Critical– Key step towards establishing an accurate

and up-to-date address list

Participation Benefits• Improved address and feature coverage

• Support current survey samples, including the American Community Survey.

• More current data and improved process flows• Minimize the impact of programs like LUCA

• Taxpayer savings

• A more accurate 2020 Census

• Evaluations, quality assessment & feedback may help

improve local data sets.

Planned Schedule for FY13-14

• October 2012– Kick‐off program with data from limited partners (@50,

TBD)

• February 2013– Start providing feedback

• March 2013– Identify 300‐400 supplemental FY13 partners based on

quality audit of MAF/TIGER data– Make “Community TIGER” available for beta testing

• October 2013– Planning for open participation

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 Census Bureau Address Data Content Guidelines:

http://www.census.gov/geo/www/gss/gdlns/addgdln.html

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 Census Bureau Address Data Content Guidelines:

http://www.census.gov/geo/www/gss/gdlns/addgdln.html

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

Feature Data and Metadata Content Guidelines:

http://www.census.gov/geo/www/gss/gdlns/addgdln.html

Summary

• Goals of the GSS initiative – Ongoing update of the MAF/TIGER database – Improve address coverage, feature coverage,

and quality in the MAF/TIGER database– Facilitate a targeted Address Canvassing

operation for the 2020 Census

• Aligns with our commitment to provide high quality products and data
