Resource Abstract:
- description: This dataset is called the Gridded SSURGO (gSSURGO) Database and is derived from the Soil Survey Geographic (SSURGO)
Database. SSURGO is generally the most detailed level of soil geographic data developed by the National Cooperative Soil Survey
(NCSS) in accordance with NCSS mapping standards. The tabular data represent the soil attributes, and are derived from properties
and characteristics stored in the National Soil Information System (NASIS). The gSSURGO data were prepared by merging traditional
SSURGO digital vector map and tabular data into a Conterminous US-wide extent, and adding a Conterminous US-wide gridded map
layer derived from the vector, plus a new value added look up (valu) table containing "ready to map" attributes.
The gridded map layer is offered in an ArcGIS file geodatabase raster format. The raster and vector map data have a Conterminous
US-wide extent. The raster map data have a 30 meter cell size. Each cell (and polygon) is linked to a map unit identifier
called the map unit key. A unique map unit key is used to link to raster cells and polygons to attribute tables, including
the new value added look up (valu) table that contains additional derived data. The value added look up (valu) table contains
attribute data summarized to the map unit level using best practice generalization methods intended to meet the needs of most
users. The generalization methods include map unit component weighted averages and percent of the map unit meeting a given
criteria. The Gridded SSURGO dataset was created for use in national, regional, and state-wide resource planning and analysis
of soils data. The raster map layer data can be readily combined with other national, regional, and local raster layers, e.g.,
National Land Cover Database (NLCD), the National Agricultural Statistics Service (NASS) Crop Data Layer, or the National
Elevation Dataset (NED).; abstract: This dataset is called the Gridded SSURGO (gSSURGO) Database and is derived from the Soil
