California, USA, 17 August 2006: ESRI announced on August 17 the development of a new ArcGIS extension to support local governments participating in the Local Update of Census Addresses (LUCA) programme for the 2010 Census.
The Census Bureau LUCA programme is a 2010 Census geographic partnership program that will allow the Census Bureau to benefit from local knowledge to improve the accuracy and efficiency of the 2010 Census by providing digital data and a review and update tool to approximately 40,000 local governments. The LUCA programme is also expected to be one of the key cost-saving programs of the 2010 Census.
The extension will read Census Bureau-provided spatial data in shapefile format, provide a toolbox of census-specific workflow tasks (incorporating business rules and data validation), and output a revised shapefile in the required census format. This extension will replicate the task and technical functionality of the census Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Partnership Software (MTPS) in an ArcGIS environment.
Jack Dangermond, president, ESRI said, “The extension will be compliant with Census Bureau standards and will provide agencies with an advanced tool for reviewing and updating spatial data for the 2010 census. It can be used with geographic information system (GIS) environments that work with the Census Bureau, helping to improve the timeliness and accuracy of census information….”
The extension development is a joint effort between ESRI and Citygate GIS LLC. The anticipated availability of the initial version of the extension is December 2006, coinciding with the availability of census-provided data and a census-developed review and update tool.
The Census Bureau is currently developing datasets in tabular (addresses and counts) and shapefile (geographic features) formats, along with a basic, no-cost mapping application to support the update of the shapefile-based information. Use of the data and application will help to ensure that the local updates can be used immediately (after Census Bureau review and acceptance) and effectively within the larger 2010 Census effort. Local governments without ArcGIS software or expertise can use the MTPS toolset to fulfill the same responsibilities under the LUCA program.
Local government entities will be requested to review and update address lists, counts of housing units, and other geographic features (roads, legal boundaries, etc.) for the areas under their jurisdictions, which the Census Bureau will incorporate and distribute from into the modernized MAF/TIGER database.
Local government entities will be presented with three options for participation in the LUCA program. The three options differ primarily in the address or housing count data mechanism that is made available as well as access and safeguards for the Title 13 (individual household) address data. The three options include the capability for local government entities to provide corrections and updates for geographic features (roads, boundaries, housing unit locations, and other geographic data provided in the TIGER database.
More information about the LUCA program and participation options is available on the Census Bureau Web site (www.census.gov/geo/www/luca2010/luca.html).
