MAF/TIGER Enhancements Program Objective Two: MAF/TIGER Redesign

MAF/TIGER Enhancements Program
Objective Two:
MAF/TIGER Redesign
December 2004

What is TIGER?

Topologically Integrated Geocoding and Referencing System

A street center-line "digital map" (geographic data base) of the entire
United States, Puerto Rico, and the associated Island Areas

1. TIGER Content:

Street center-lines and their names
Lakes, streams, and their names
Railroads
Geographic entity boundaries, names, and
codes (for governmental units, census tracts, census blocks, etc.)
Housing unit locations (selected areas)
Key geographic locations (for airports, schools, etc.)
ZIP Codes and address ranges (for streets with city-style addresses)

Small map of streets and other features in TIGER

2. What is the MAF?
Master Address File

Title 13 requires that all addresses/locations be kept confidential

An accurate and up to date inventory of all known living quarters in the United States, Puerto Rico, and associated Island Areas

The content of the MAF is:

Mailing address, if one exists
Descriptive address, when no city-style address exists
Census geographic location
Source and history data

3. MAF/TIGER:
Mission Critical Corporate Resource

System provides storage, processing, products and services that support agency's statistical programs.
- Geocoding
- Maps
- Residential Address Lists
Continually updated with new address and geographic information.
Wide public use of geographic information.

4. MAF/TIGER Redesign:
Objective 2 of MAF/TIGER Enhancements Program

The MAF/TIGER Redesign will:

Replace the existing home-grown databases with a commercial relational database.
Replace the application software that utilizes these databases.
Integrate MAF and TIGER into a seamless national database.

5. MAF/TIGER - Old vs. New System

Existing System	New System
Home-Grown Database MAF & TIGER Separate Commercial Off the Shelf Software (COTS) Use is Limited Extensive Developer Training Required County Partitions Single-User Update Closed, Proprietary Development Environment Client/Server Ad Hoc Software Development	Oracle MAF & TIGER Integrated COTS Use is Expanded Can Recruit Developers with Appropriate Skills Seamless National Database Concurrent Read/Write Open, Interoperable Formats and Tools Web-Based CMM Level 2

6. Advantages of the New System

Facilitates data exchange with local partners.
Improves data accessibility and currency, using standard GIS tools.
Greater flexibility and efficiency in responding to new or changed requirements.
Use of commercial database and current technology facilitates recruitment/training.
Seamless national database improves ability to respond to customer needs for product delivery mechanisms or partitioning.
More efficient data exchange with 2010 Census handheld computers.

7. MAF/TIGER Redesign
High Level Project Plan

Activity	Date
Planning & Requirements	Fiscal Year (FY) 2002 - 2004
System Design	FY 2003 - 2004
Software Development	FY 2005 - 2006
System Testing	FY 2006
Data Migration & Deployment	Late FY 2006

8. Issues and Risks

COTS Software - Functionality, Extensibility, Interoperability, Upgradeability.
Hardware Resources - Existing hardware aging; Old and new systems must run simultaneously.
Human Resources - Maintaining existing system while building new one.
Coordination of Architecture Design with 2010 Census Efforts.

9. Relationship to Other MAF/TIGER Enhancements Program (MTEP) Objectives

Developmental work and testing will proceed in the background while program applications (including those needed for other MTEP objectives) use the existing databases.
Once critical applications are developed and tested to work on the new database, a migration process will begin, with the goal of causing the least disruption and downtime to existing processes.
Both the existing TIGER database and the new one are capable of storing corrected coordinate information and attributes obtained from Objective One of MTEP.

10. Major COTS Tools Selected

Database	Oracle
Spatial Storage	Oracle Spatial Topology Data Model
Requirements	DOORS
Configuration Mgmt	Serena Version Manager (formerly PVCS)
