Indiana Statewide GIS database was produced under an Indiana Department of Transportation contract. Data is from U.S. Department of Commerce, U.S. Census Bureau, Census 2000 Tiger Line Files and SF1 tables. Polygons were obtained from a county boundary shapefile produced by the Indiana Geological Survey. US Census Bureau requests "Acknowledgment of the U.S. Census Bureau would be appreciated for products derived from these files." Indiana Geological Survey requests "Indiana Geological Survey be cited in any products generated from this data. The following source citation should be included: [LANDSURVEY_COUNTY_POLY_IN: County Boundaries of Indiana (Indiana Geological Survey, 1:24,000, Polygon Shapefile)]." |
