Updating the U.S. Census Bureau’s geospatial database with information from state, local, and tribal government partners

The U.S. Census Bureau maintains the MAF/TIGER geospatial database (MTDB) in support of various surveys and censuses. For the 2010 Census, the agency conducted a costly nationwide Address Canvassing field operation to ensure a complete address list. The Census Bureau has proposed and is currently researching the feasibility of relying on state, local, and tribal governments to provide current address and spatial data to support a targeted, rather than complete, Address Canvassing operation during 2019 in preparation for the 2020 Census and ultimately establish an acceptable address list for each level of government.

For the Census Bureau to be able to acquire, assess, and process partner-supplied datasets to update the MTDB, a process had to be developed with various components designed and built using vendor solutions including Oracle Database with Oracle Spatial and Graph option, Esri’s ArcGIS, Safe Software's Feature Manipulation Engine (FME), and 1Spatial's Radius Studio. The update process involves interactive and automated components significant among them being the automated conflation solution.

This presentation will give details of various systems built in support of the update process, and experiences so far in using those systems.
