Attribute data as defined by the Natural Resources Conservation Service (NRCS) contained in Chester County GIS Enterprise version of the digital soil survey. The extraction combines the spatial features of the Dept. of Agriculture soil survey with a subset of soil attribute data. 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. 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. A subset of these attributes have been appended to the Chester County version of the file for convenient use.
