Description: <DIV STYLE="text-align:Left;"><DIV><DIV>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 State-wide extents, and adding a State-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 State-wide extent. The recently released (2011) gSSURGO value added look up (valu) table (created by USDA-NRCS) 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.Summarized description of the Format and organization of SSURGO:<UL><LI>Adjacent soil surveys may have been composed by different individuals, and may be of widely different vintages. Any given survey must comply with basic standards, but older surveys reflect a more generalized approach than more modern surveys. The figure to the right illustrates such differences.</LI><LI>Polygons represent a repeating pattern of legend entries: groups of map-able soil concepts called map units</LI><LI>Map unit data is stored in the mapunit table, and is referenced by the field mukey</LI><LI>Pre-aggregated map unit data is stored in the muaggatt table, and is referenced by the field mukey</LI><LI>Map units are comprised of multiple, unmapped soil types called 'components'</LI><LI>Component data is stored in the component table, and is referenced by the field cokey</LI><LI>Soil components (or soil type) are associated with multiple horizons</LI><LI>Horizon data is stored in the chorizon table, and is referenced by the field cokey</LI><LI>Since there is a 1:many:many (mapunit:component:horizon) relationship between spatial and horizon-level soil property data two aggregation steps are required in order to produce a thematic map</LI></UL>Source: <A href="http://casoilresource.lawr.ucdavis.edu/drupal/book/export/html/335">http://casoilresource.lawr.ucdavis.edu/drupal/book/export/html/335</A>Summary Descriptions of gSSURGO Soil Survey Attributes contained within the MUAGGATT table.MUAGGATT Table:<UL><LI>Slope Gradient - Dominant Component</LI><LI>Slope Gradient - Weighted Average</LI><LI>Bedrock Depth – Minimum</LI><LI>Water Table Depth - Annual Minimum</LI><LI>Water Table Depth - April to June Minimum</LI><LI>Flooding Frequency - Dominant Condition</LI><LI>Flooding Frequency – Maximum</LI><LI>Ponding Frequency – Presence</LI><LI>Available Water Storage 0-25 cm - Weighted Average</LI><LI>Available Water Storage 0-50 cm - Weighted Average</LI><LI>Available Water Storage 0-100 cm - Weighted Average</LI><LI>Available Water Storage 0-150 cm - Weighted Average</LI><LI>Drainage Class - Dominant Condition</LI><LI>Drainage Class – Wettest</LI><LI>Hydrologic Group - Dominant Condition</LI><LI>Irrigated Capability Class - Dominant Condition</LI><LI>Irrigated Capability Class - Proportion of Mapunit with Dominant Condition</LI><LI>Non-Irrigated Capability Class - Dominant Condition</LI><LI>Non-Irrigated Capability Class - Proportion of Mapunit with Dominant Condition</LI><LI>Rating for Buildings without Basements - Dominant Condition</LI><LI>Rating for Buildings with Basements - Dominant Condition</LI><LI>Rating for Buildings with Basements - Least Limiting</LI><LI>Rating for Buildings with Basements - Most Limiting</LI><LI>Rating for Septic Tank Absorption Fields - Dominant Condition</LI><LI>Rating for Septic Tank Absorption Fields - Least Limiting</LI><LI>Rating for Septic Tank Absorption Fields - Most Limiting</LI><LI>Rating for Sewage Lagoons - Dominant Condition</LI><LI>Rating for Sewage Lagoons - Dominant Component</LI><LI>Rating for Roads and Streets - Dominant Condition</LI><LI>Rating for Sand Source - Dominant Condition</LI><LI>Rating for Sand Source - Most Probable</LI><LI>Rating for Paths and Trails - Dominant Condition</LI><LI>Rating for Paths and Trails - Weighted Average</LI><LI>Erosion Hazard of Forest Roads and Trails - Dominant Component</LI><LI>Hydric Classification – Presence</LI><LI>Rating for Manure and Food Processing Waste - Weighted Average</LI></UL></DIV></DIV></DIV>
