Description
Representation of mapped surficial soil units created by the Idaho Office of the
National Resource Conservation Service (NRCS).
Soils have been assigned a percolation rate based on the average,
saturated hydraulic conductivity of the soils as classified using the
Unified Soil Classification System (USCS).
Usage
1
Format
An object of SpatialPolygonsDataFrame class containing 718 Polygons and a
data.frame with the following variables:
- GroupSymbol
soil class identifier
- SoilLayer
identifier used to differentiate the soil data source
used to create the soils map.
Data sources are either ‘USCS’ or ‘STATSGO’,
the NRCS State Soil Geographic Data Base.
- SoilClass
description of the soil class.
- MinRate
lower percolation rate limit for the soil class, in meters per month.
- MaxRate
upper percolation rate limit for the soil class, in meters per month.
- PercolationRate
percolation rate in meters per month.
Geographic coordinates are in units of meters, in conformance with the
North American Datum of 1983 (NAD 83), and placed in the
Idaho Transverse Mercator projection (IDTM).
