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)]."
"All county names contained in the fields named "NAME_U" and "NAME_L" were checked against the USGS 7.5-minute quadrangles. The prefix code contained in the field named "NCAPC" was checked against the AccessIndiana Indiana Bureau of Motor Vehicles license plates and titles county prefixes listed on license plates. US Census Bureau makes no claim as to the accuracy of its SF1 table attributes. See Census Technical Documentation for more information."
"A check was made for dangling nodes and none were detected."
"A check was made to verify that the county boundaries are continuous and are identical to the county boundaries contained in IN_LANDSURVEY. Census SF1 table attributes were joined for all counties."
"Accuracy is no better than that of the source material. The vector lines contained were corrected to DRG raster lines at an on-screen scale of 1:5,000 or better. Polygon data is a digital representation of land survey features as represented on the USGS 1:24,000 digital raster graphic (DRG) series."
