Description of NeuseSurfaceWater
The NeuseSurfaceWater geodatabase is located at ftp://geo1.tacc.utexas.edu/Neuse.
NeuseSurfaceWater contains two feature datasets, two raster catalogs and one time series table as shown below:
The ArcHydro feature dataset contains thirteen feature classes obtained from several sources.
The MonitoringPoint feature class contains NWIS stream flow measurement stations, RainStations contains NCDC rainfall stations, WQPoints contains NWIS water quality measurement points, GWPoints contains NWIS groundwater measurement points, RiverNetPoints contain water quality measurement points operated by North Carolina State University, and HRAPPoints contain center points of the HRAP grid for the Neuse basin. The data layers are shown below.
HydroJunction is a subset of monitoring point feture class, and the Watershed feature class contains drainage areas delineated for HydroJunction points by using ArcHydro tools. HydroEdge contains stream network for the neuse basin created by using medium resolution (1:100000) NHD reaches. NHDArea and NHDWaterBody are waterbody features from NHD. HydroJunction, HydroEdge and Watershed feature classes are related to each other through HydroID.
The Geology feature dataset contains five feaure classes obtained from several sources.
STATSGO and SSURGO are soil data from NRCS, NeuseAquifer contains aquifer polygons, and NeuseFaults contains fault lines for the geologic structures in the Neuse basin.
The SurfaceRasters raster catalog contains four rasters.
NeuseDEM is a 50 feet DEM created by using LIDAR points, NeuseLULC is the land use/land cover data from EPA, and NeuseFAc and NeuseFdr are the flow accumulation grid and flow direction grid, respectively derived from NeuseDEM by using Arc Hydro terrain processing tools.
The ModisData raster catalog contains 23 images stored as raster grids. The value for each cell in these rasters represent enhanced vegetation index (EVI). Two sample grids with EVI on two different days around the Neuse basin are shown below:
The TimeSeries table for NeuseSurfaceWater contains time series records for water quality, streamflow and precipitation. The details about each variable can be found in the TSType table as shown below:
The TSType table is related to time series table through TSTypeID, and the TimeSeries table is related to featureclasses through HydroID (relationships shown below). The TimeSeries table contains data for Monitoringpoint, HRAPPoints, RainStations and RiverNetPoints feature classes.
