The maps are created by merging the modeled estimates in database format, with geographic boundary files, called shapefiles. In this manner, the statistical data in the database are spatially referenced with their associated state and county boundaries. As a result, the data can be viewed as a map and the user can interactively map the geospatially-based data. Users can specify the use of natural breaks or quartiles to classify the data. The NAD 1983 UTM Zone 14N map projection was used for state maps. The Albers Equal-Area (Continental United States) projection was used for national maps.
