Enhancing MAF/TIGER Database Update Processes: Strategies and Tools

This document discusses current and proposed strategies for updating the MAF/TIGER database, focusing on various interactive and batch processes. Key methodologies include Conflation (MTAIP), Batch Features Update System (BFUS), and interactive updates using GATRES and ArcDesktop. A case study of the 2009 Address Canvassing Operation highlights the scale of updates, including over 2.7 million updates and new road features. GATRES is introduced as a flexible tool for boundary management. The document also explores ongoing operations and methods ensuring the MTDB remains current and comprehensive.

  1. Updating the MAF/TIGER DB Batch and Interactive processes John S. Liadis Update Operations Branch

  2. Current Update Strategies • Conflation (MTAIP) • Batch (BFUS) • Interactive (using GATRES) • Interactive & Batch (using ArcDesktop) • Edit Based (TAGIT, Business Rules, etc.)

  3. Proposed Update Strategies • Volunteer Geographic Information (VGI) • Web Feature Service

  4. Updating the MTDB • A recent example of a major operation providing updates to the MTDB was the 2009 Address Canvassing Operation. More than 140,000 enumerators collected addresses in the field as well as spatial information. More than 2.7 million updates including 623,000 added road features and 758,000 deleted road features were submitted for processing. • The Geo processed the updates through the Batch Features Update System (BFUS)

  5. Feature Update Return Statistics Number of Records by Action and Capture Methodology

  6. Flow of MTDB Update Operations thru BFUS

  7. Distribution of Updates from ADCAN

  8. Feature Add Issues Of all added features: • 53.4% were automatically added to the MTdb. • 20.7% were added to the MTdb after review. • 26.0% were reviewed interactively, of these: - one half were rejected as unnecessary updates (13% of all road feature adds)

  9. What is GATRES? • GATRES is the interactive COTS software tool that allows the user to create, modify, and view boundaries, linear features, address ranges, areal features, etc., in the MTDB. • GATRES is “A Work in Progress” • Additional functionality will be available in future releases

  14. Summary • The MTDB is updated • from a variety of ongoing update operations including BAS and ACS. • by a variety of update methods including interactive and batch updates derived from field update instrument capture, partner provided files, interactive targeted updates, edit reconciliation, etc. • using the Batch Feature Update Software and the GATRES software in combination with edits, local files, field updates, office updates using a variety of devices and software.
