In SSN2: Spatial Modeling on Stream Networks
#' MiddleFork04.ssn: Middle Fork 2004 stream temperature dataset
#'
#' The \code{MiddleFork04.ssn} data folder contains the spatial, attribute,
#' and topological information needed to construct an SSN object using
#' the \code{SSN2} package.
#'
#' The \code{MiddleFork04.ssn} folder contains five shapefiles:
#'
#' \itemize{
#' \item edges: polyline shapefile representing the stream network
#' \item sites: point shapefile representing the observed site locations
#' \item pred1km: point shapefile representing prediction site locations at
#' approximately 1km intervals throughout the stream network
#' \item Knapp: point shapefile representing prediction site locations on the Knapp River
#' \item CapeHorn: point shapefile representing prediction site locations on the Cape Horn River
#' }
#'
#' The \code{MiddleFork04.ssn} includes one text file, \code{netID1.txt}, which contains the
#' topological information for the stream network in the Middle Fork 2004
#' dataset.
#'
#' The distance folder contains four folders that store the hydrologic
#' distance matrices for each of the point shapefiles (\code{obs}, \code{CapeHorn},
#' \code{Knapp}, and \code{pred1km}). See [ssn_create_distmat()] for a
#' detailed description of the distance matrix file structure.
#'
#' Attribute data is also stored within each of the spatial
#' datasets. The column names are defined as follows:
#'
#' \code{edges}:
#' \itemize{
#' \item COMID: Common identifier of an NHD feature or relationship
#' \item GNIS_Name: Feature name as found in the Geographic Names Information System
#' \item REACHCODE: Unique identifier for a reach. The first 8 digits contain the identfier for the HUC8 and the last 6 digits are a unique within-HUC8 identifier for the reach
#' \item FTYPE: three-digit integer used to classify hydrography features in the NHD and define subtypes
#' \item FCODE: Numeric code that contains the feature type and its attributes as found in the NHDFCode lookup table
#' \item CDRAINAG: Cumulative drainage area (km2) for the lowermost location on the edge
#' \item AREAWTMAP: Area weighted mean annual precipitation (mm) at the lowermost location on the edge
#' \item SLOPE: Slope of the edge (cm/cm)
#' \item h2oAreaKm2: Watershed area (km2) for the lowermost location on the line segment
#' \item rid: Reach identifier
#' \item areaPI: Segment proportional influence value, calculated using watershed area (h2oAreaKm2)
#' \item afvArea: Additive function value, calculated using areaPI
#' \item upDist: Distance from the stream outlet (most downstream location in the the stream network) to the uppermost location on the line segment
#' \item Length: Length of line segment (m)
#' \item netID: Network identifier
#' }

#' \item C16: Number of times daily stream temperature exceeded 16C
#' \item C20: Number of times daily stream temperature exceeded 20C
#' \item C24: Number of times daily stream temperature exceeded 24C
