## MAF/TIGER Accuracy Improvement Project

**Next Steps:**
**Phase 1: (Underway)**
**Census Bureau staff working with Harris Corporation staff to detail out the production requirements**
**Phase 2:**
**Census develops/continues partnerships with state/local/tribal governments**
**Harris performs work for all 3200+ counties and completes initial work by FY 2008. **
**Change detection/maintenance for counties completed early in the process**

## MAF/TIGER Accuracy Improvement Project

**Importance to State/Local/Tribal Governments**
**Will put the Census Bureau on the same base as the state/local/tribal GIS data bases where they exist, have the spatial accuracy to use with GPS, and provide them to the Census Bureau**
**Will enable easier exchange of spatial information between state/local/tribal governments and the Census Bureau (Boundaries and Features)**
**Road and Governmental Unit Boundaries will be provided to the National Map**

## MTEP Objective 3

**Expand and encourage geographic partnership programs**
**2004 Census Test**
**LUCA Test of Two Options**
**Full Address List Review (Title 13)**
**Review Block Counts Only (not Title 13)**
**Address List Review Program**
**Design/Testing/Pilots in 2003**

**Notes:**
To deal with all these issues and challenges, the Census Bureau has developed a MAF/TIGER Enhancements plan designed to “modernize” several aspects of the MAF/TIGER System.  The activities associated with this plan are organized around meeting five major Objectives.  These Objectives will supplement and extend the “routine” update and maintenance activities that the Census Bureau already undertakes each year – twice yearly additions of new addresses to the MAF from the USPS’s DSF – and the new streets this process causes to be added to TIGER; updated governmental unit boundaries from the Boundary and Annexation Survey; and, the “upkeep/maintenance” of the “home-grown” MAF/TIGER data base (until it is replaced), as well as the associated data base update and applications software (until they are replaced), that makes the current system run, produce the products, and provide the services that the Census Bureau uses every day to support its many and varied statistical programs. Let’s take a look at these Objectives. 

Objective One, and the issue about which most discussion already has occurred today, is correcting the locations of all existing streets and other map features used to orient field staff (in TIGER), along with the locations of all existing housing units (in the MAF).  This requires “once over” correction/re-alignment of the entire TIGER data base.

Another aspect of Objective One is to implement automated change detection methods to identify areas that have new streets and new structures, so Census Bureau staff can implement appropriate activities to gather and insert accurate address (MAF) and street (TIGER) updates.  

Data Users and geographic partners outside the Census Bureau – and field staff inside the Census Bureau – share this common goal:  They just want MAF/TIGER to be “perfect” – to show every street, every locational landmark, and every address exactly where it is, and to keep track of every change that takes place as soon as it takes place.  We’ll talk in more detail about how we plan to do this later in the presentation.

Objective Two, to develop and deploy a new MAF/TIGER processing environment by using a COTS database to replace the existing “home-grown” system, and GIS tools to replace the existing database update, geocoding, and mapping applications software.

The same group of data users and geographic partners outside the Census Bureau – and the same field staff inside the Census Bureau – share this second common goal:  They want full implementation of Web-based review, update, and product generation systems.
