Figure 4.6 illustrates the conceptual process that is executed by the TimeSeries Transfer tool.Figure 4.6 Associating NEXRAD Data with WatershedsBased on the above discussion, the “Time Series Transfer” tool requiresthe filename and location of the NEXRAD cells polygon layer (normally storedunder the HydroResponseUnit feature class in Arc Hydro), the filename andlocation of the layer containing the basin subdivisions stored under the Watershedfeature class in Arc Hydro, the layer corresponding to the intersection of theprevious two layers (NEXRAD cells and Watersheds), and the filename andlocation of the time series table storing the precipitation values associated with theNEXRAD cells. The output from this process (green oval) corresponds to thefilename and location of the created time series table with records now associated77
