Landscape layers and associated watershed metrics. Grey-colored rows provide descriptions of geospatial landscape layers. Below the description of each landscape layer, we provide a list of metrics that were derived from this layer for both local catchments (Cat) and watersheds (Ws). Human-related metrics (e.g., urbanization) are colored pink. Metrics associated with natural variation in landscapes are colored light blue. | |||||||||||||

NHDPlus(NHDPlus Region ID).shp – GIS line shapefile of the National Hydrography Dataset (version 2.1) representing all stream networks and hydrologic connections within the CONUS based on digitized 100-K USGS topographic quadrangles. Lines represent stream networks that are divided into segments, where each segment represents a section of river between upstream (except for headwater segments) and downstream confluences. Each segment has been attributed with several physical stream characteristics, such as local catchment and upstream watershed areas, segment slope, mean segment elevation, and mean upstream catchment air temperature (from PRISM climate data). In addition to natural hydrologic features, the NHDPlustV2_1 includes canals, ditches, and piplines.

Rp100(NHDPlus Region ID) – GIS raster used to confine landscape metric calculations to within ~100 meters on each side of the NHDPlus stream network. The raster was developed from the NHDPlus stream network and the NLCD open water class to create accurate water boundaries. The NHD boundaries were found with the NHDFlowline.shp file selecting out the lines with an FType equal to 'Artificial Path', 'Connector', or 'StreamRiver' and converting to a raster using the PolylineToRaster tool. The RegionGroup tool and Conditional statements produced the water boundary raster to measure the buffer from using the Euclidean Distance tool. Pixels with distance values ≤100 were converted to value=1 and all else remained NoData (Conditional function of the ArcGIS Spatial Analyst Extension). A raster was created for each NHDPlus Region to facilitate processing and the NHDPlus Region ID was appended to the raster name. NHD Plus v. 2.1 download date: 10 Feb 2014.
