Census TIGER File Maintenance

1. Census TIGER File Maintenance MARIS Briefing for MS State and Local DSL February 25, 2004 Chuck O’Hara

2. Project Overview • A congressionally-funded program to conduct research for the maintenance of Census TIGER file data. • The project technical proposal was developed to establish and validate the use of high-resolution satellite image data for technologies to support the TIGER data maintenance program of the Bureau of Census. • Generate findings that motivate use of developed technologies by BOC, other federal agencies, and local government. • Perform necessary research to assure change detection and feature extraction capabilities provide results with needed accuracy, precision, and cost-effective characteristics.

3. Census TIGER File Maintenance Project The TIGER File Maintenance Project will validate the use of high-resolution satellite image data for land use change detection and feature extraction technologies that could provide support to the Bureau of Census TIGER data maintenance program.

4. Census TIGER File Maintenance Project The project will use enhanced multi-spectral remote sensing imagery for extracting features of interest for maintaining spatial feature databases to federal agencies [such as the Bureau of Census] as well as to state and local agencies for updating and maintaining their spatial databases.

5. Census TIGER File Maintenance Project A benchmark example of accomplishing spatial database updates through improved technology use, the Bureau of Census TIGER Modernization Project employs spatial information technologies to significantly improve the nation’s important Census data. The Topologically Integrated Geographic Encoding and Referencing (TIGER) database will be modernized as part of a re-engineered 2010 Census. The five major objectives of the modernization project are to: 1) Correct locations of streets, other map features, and housing units; identify new streets/housing units using automated change detection methods (MAINTENANCE) 2) Develop/deploy a new MAF/TIGER processing environment based on COTS and GIS tools 3) Expand and encourage geographic partnership programs 4) Launch the Community Address Updating System (CAUS) 5) Implement periodic evaluation activities
