WetlandConnectivity. v1.0

Description

A CONUS-wide dataset containing this information is available. For each of 59 hydrologic sub-regions of the CONUS, the dataset consists of three components: (1) A raster that contains NHDPlusV2 streams, NLCD water pixels, and the flowpaths that connect wetlands and downstream waters. (2) A wetland raster that contains the WetId of each wetland, where each WetId corresponds to a single stand-alone wetland pixel or a group of adjoining wetland pixels. Note that WetIds are not globally unique, but are unique within each of the 59 sub-units of NHDPlusV2 Hydrologic Regions (i.e., Raster Processing Units – RPUs). Within these RPUs, each WetId contains only a single pour point. (3) A table of wetland characteristics indexed by WetId, including wetland area, and wetland hydrologic connectivity class.A CONUS-wide dataset containing this information is available.
