MTAIP Vision

• A Seamless Digital Map of the United States Where
  Street Centerlines Are Based on
  State/County/Local/Tribal GIS Files and the
  Digital Features Are Publicly Available Via
  Standard OGC Protocols

4
TIGER

• 1988 The First Nationwide Digital Street
  Centerline File
• 2008 Improved Nationwide Digital Street
  Centerline File Consistent with GPS
• Support the 2010 Census Operations Beginning in
  GFY2009

Thank You For Making The Vision Come to Fruition

• For the GIS Files you have provided
• For the Metadata you have provided
• For Helping With TED
• For Reviewing Future Work Schedule

6
MTAIP Source Acquisition Strategy

• Government GIS Files
• Must pass 7.6 meter CE95 spatial accuracy
• No restrictions on derivative products
• We recognize that it takes labor for States to
  provide the data to Census
• We will make available an external hard drive to
  make the transfer of data easier (no need to cut
  CDs or DVDs)

7
MTAIP Source Acquisition Strategy

• Harris Corporation responsible for all remaining
  source acquisition
• Existing Imagery (especially NAIP)
• Subcontracts for centerline extraction
• Existing Commercial GIS Files
• Last Resort
• Subcontract for Street Centerline collection
• New Imagery Collection where total cost less than
  Street Centerline collection

8
Governmental Sources(Entire Counties)

• Over 2000 counties acquired
• Evaluated over 1500 counties
• Two/Thirds Of The Files Evaluated Are 7.6 meters
  CE95 Or Better In Spatial Accuracy

9
What About The Failed Files

• They have attributes that can improve TIGER
• Planned
• Develop new software
• To utilize the attributes
• Case-by-case basis after evaluation

10
An Option For Failed Files

• Improve these files so they meet the spatial
  accuracy requirement
• Source Provider May Rework
• Harris Corporation May Improve Spatial Accuracy
• Must be less expensive than other options, such
  as a commercial GIS file or extraction from
  imagery
• Census must be able to obtain permission from the
  source provider

11
Status Maps

• Are Available On The Web

MTAIP Production Schedule

• Counties are scheduled in early summer each year
  for the next fiscal year
• Schedule for the remaining counties is revised
  each summer
• Need to have all government provided files in
  house by April, 2006
• Fiscal Year 2005 county workload is specified in
  contract

14
FY05 Plans

• List of Counties for Improvement
• 251 Tribal/State/County GIS
• 14 Partial Counties
• 345 Harris Acquired Sources
• Commercial GIS
• Existing imagery centerline extraction
• Field Collect

15
FY06-FY08 Planning

• Estimating where we will have existing GIS files
• We will modify our current proposal based on your
  comments
• Last files need to be ready to go to Harris
  during FY07
• Need to have all counties back from Harris by
  April, 2008
• Necessary to allow for Census processing and
  preparations for Address Canvassing Operations

16
MTAIP Feedback to source providers

• Report on spatial evaluation of the provided
  source
• 2004 TIGER/Line files First Edition
• Includes feature level metadata on coordinates
• State/local/tribal source providers will be
  provided with a Local Edition TIGER/Line File
• Will include additional record types (beyond
  those in the 2004 TIGER/Line File) that will
  contain local feature name and/or address range
  information as provided to the Census Bureau
  (except for single address address ranges)

17
Maintenance

• Where possible, we would like to obtain a later
  version of the State/County/Local/Tribal files to
  further update TIGER
• This processing would be done by the Census
  Bureau
• As part of 2010 Census, there will be a complete
  address canvass that will
• Capture Master Address File structure points
• This is Confidential (Title 13) Information
• Capture new street features using a GPS-equipped
  device
• Will be available in future releases of TIGER

18
Maintenance Post 2010

• Census will continue to update TIGER based on
  newer versions of Government GIS files
• Census Bureau Field Operations
• Staff will use GPS equipped devices to continue
  to locate new housing units/MAF structure points
• We continue to want your thoughts on how we might
  work with you to update areas where there are no
  files
• How to target
• Use of available imagery
• Can the private sector help?

19
TIGER Availability

• Traditional Web-based Downloads
• Via OGC Standard Protocols
• Web Feature Server
• Web Map Server

20
Road to 2010 Census

• LUCA
• Local Update of Census Addresses
• Statistical Areas Program
• Census 2000 Participants will be invited to
  participate in the 2010 program
• Anticipate a fully electronic program
• Where we have realigned TIGER to the local GIS
  file, participant only needs to submit the
  proposed Statistical Area Plan as boundary files
• Looking at a method for our Regional Offices to
  Review the plans via a web-based application

21
Road to 2010 Census

• Boundary and Annexation Survey extended to all
  incorporated places beginning in 2008 to support
  the 2010 Census
• Boundary Validation Program
• Summer of 2010
• Boundaries to be used for data tabulation
