This dataset is a compilation of soil map unit polygons and associated attributes used to develop the Virginia ConservationVision Agricultural Model. It was developed by staff at the Virginia Natural Heritage Program, using data extracted from the gSSURGO geodatabase for Virginia. The gSSURGO dataset (gSSURGO_VA.gdb) was retrieved from the Geospatial Data Gateway in May 2015.

The gSSURGO dataset 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 dataset consists of georeferenced digital map data and computerized attribute data. The map data are in a state-wide 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.
