Description

The Geography Division, United States Census Bureau (Census Bureau) is conducting a competition to enter into a long-term contract (with a base period from award date through September 30, 2002, and four (4) annual option periods through September 30, 2006)for the delivery of a more accurate TIGER database, a structure coordinate with an address for each that can be linked with the Master Address File (MAF), and a proposed maintenance mechanism (detecting change) for the TIGER database and the inventory of structures. The MAF/TIGER Accuracy Improvement Project Objectives are: a. Improve the Accuracy of the TIGER Database -- A major objective of this contract is to enhance the accuracy of the coordinates in the TIGER database for all of the counties and statistically equivalent entities in the United States, Puerto Rico, and the associated Island Areas. The specific content of the TIGER database that requires alignment includes roads, hydrography, railroads, structures, landmarks, pipelines, power lines, etc. The horizontal accuracy required for re-alignment of TIGER coordinates (including structures) is such that the geographic positional coordinates will correctly place an enumerator, relying on a GPS receiver, at the desired structure 100 percent of the time, on the correct side of the street (i.e., in the correct Census Block) 100 percent of the time, and the structure is in the correct relationship to corporate boundaries, other boundaries, and neighboring structures 100 percent of the time. Federal, state, local and tribal government data, as well as commercial data, that meet acceptable specifications, will be used to re-align TIGER whenever available. When a county or statistically equivalent entity is assigned for re-alignment the federal, state, local and tribal government data, as well as any commercially available data, will be provided by discussions held as part of the Geography Division/contractor partnership. If the assigned contractor is aware of additional data for its assigned county, notification should be made to the Geography Division for consideration of acceptance. The resulting corrected file must have all features and structures that exist within one year of the time of delivery. b. Association of the Accurate TIGER Database with MAF Addresses -- The association by the contractor of a city-style mailing address with each structure coordinate is a requirement. When a structure does not have a city-style mailing address, the requirement is to provide a coordinate, the actual mailing address, and an E-911 address, if one exists. c. Enhance Relationships with Federal, State, Local, and Tribal Governments -- The success of the alignment of the TIGER database and the continuous update of the information in the database requires the interaction of the Census Bureau with the federal, state, local, and tribal governments. A large amount of the data to correct the TIGER database is currently available from these organizations. The use of this already available data must be considered prior to any other options for alignment. The maintenance of the TIGER database must incorporate the updates provided by federal, state, local, and tribal governments. d. Maintain MAF/TIGER by Detecting Change -- The modernization of MAF and TIGER has an anticipated completion date prior to FY 2008 in preparation for the Census Bureau's 2010 Census dress rehearsal. The MAF/TIGER database must be maintained to a currency of less than 1 year old at all times. The partnerships with federal, state, local, and tribal governments must be maintained as part of the update system put into place. Beginning in FY 2004, updates must be made to the TIGER database that will note the additions and deletions of structures, roads, railroads, hydrography features, etc. This maintenance must remain ongoing indefinitely and ensure that new features are updated within the prescribed time period. When the TIGER database is updated with additions or deletions, the MAF database also must be updated concurrently. The anticipated award date is May 10, 2002. All responsible sources may submit an offer which will be considered by the Census Bureau. Expressions of interest and requests for the solicitation document should be forwarded via Email to the above contact. See Note 2.
