Regional Director

2. Census Geographic Support – Major Initiatives Over Time
2010 Census – MAF/TIGER Enhancement Program
including MAF/TIGER Realignment (7.6 meter min. accuracy)

3. What is the GSS-I? Improved address coverage
Continual address and spatial database updates
Enhanced quality assessment and measurement
Improved Partnerships

4. 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 Census
2015

5. Major Components of 2010 Census Address List Development

6. Full Address Canvassing is VERY expensive:
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

7. 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

8. GSS-I Goal: Address Coverage
123 Testdata Road
Anytown, CA 94939
Lat 37 degrees, 9.6 minutes N
Lon 119 degrees, 45.1 minutes W
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

9. 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

10. GSS-I Goal: Quality Assurance Goals
1: Establish quantitative measures of
address and spatial data quality
2: Assign Quality Indicators to
MAF/TIGER data

11. GSS-I Goal: Improved Partnerships
Volunteered Geographic Information (VGI)
Web-based Address
Management Tools
Data upload systems
TIGERweb
New Tools
Partners
Enhanced Feedback
New and Enhanced Programs
Enhanced collaboration
Expand Existing
Partnerships
Engage New
Partners
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

12. 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

13. 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

15. Minimum Address Guidelines

16. 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)

17. 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?

18. Feature Requirements
Forthcoming… Check our GSS-I webpage for updates as they occur:

19. GIS Inventory (aka Ramona)

20. GIS Inventory: Indiana Status

21. Address Points

22. County Consolidated BAS Boundary & 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

23. County Consolidated BAS Boundary & Annexation Survey
Local Boundary
TIGER BAS Boundary

24. Action Items:
Create a Ramona Account and register your data (
Counties: Establish a County Consolidated BAS with us
Review the FGDC Address Standard and get your data in shape…
