NRCS SSURGO Soils in Kentucky

Data represents a copy of Standard SSURGO from USDA-NRCS. The 85 separate KY SSURGO Survey areas have been appended by USDA-NRCS-KY into file geodatabase format (and corrected for topology rules/gaps/overlaps). The File GDBs also contain an extensive list of ‘pre-built’ attributes compiled from official SSURGO tabular data by USDA-NRCS KY. The GIS data is also provided in shapefile format by Soil Survey Area (85 separate) and by County (120 separate). This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.
