Abstract: Experiences with Exadata and Oracle Spatial at US Census Geography Division


View Presentation

The Geography Division (GEO) of the US Census Bureau adopted the Oracle Spatial on Exadata solution for its geospatial database, the Master Address File (MAF)/Topologically Integrated Geographic Encoding and Referencing System (TIGER). GEO successfully migrated (including multiple terabytes of geospatial data) from their legacy systems to their new Exadata based development, test and production environments. This presentation highlights the planning and execution phases of the migration project, and delves into the benefits of the Exadata solution realized so far. Details about the exploration of Oracle Exadata and its benefits to GEO and beyond (exploratory phase) will also be presented, along with the details of Oracle Ex-cite process and the collaboration between GEO and Oracle (including the Oracle Spatial team) that led to a successful testing, procurement, installation, implementation and migration.

He is responsible for the development and implementation of IT solutions for the management of Topologically Integrated Geographic Encoding and Referencing (TIGER) System, which is one of the largest geospatial databases in the world. He has been with Census for about 15 years, and was intricately involved in the MAF/TIGER (MT) Redesign project as part of the MT Enhancement Program (MTEP). He was instrumental in the development of a Business Rules Engine, and successfully implemented complex algorithms such as feature chaining in the core application programming interface for TIGER. He played a key role in the migration of over 3,200 counties worth of spatial data from legacy to modernized TIGER that is built on Oracle Spatial and Topology Data Model. He also managed the 2010 Decennial production operations as Chief of Workflow Control Branch of the Geography Division.
