HMS-PrePro contains ArcGIS geoprocessing script tools for extracting data from Esri's Living Atlas, deriving a watershed network, estimating hydrological parameters, and storing results in a .BASIN output ASCII file that may be used as rapid input for initializing a basin model in the HEC-HMS watershed modeling software.


This product requires ESRI ArcGIS v10.xx, 3D Analyst, Spatial Analyst, and Arc Hydro. ArcGIS Desktop Background Processing 64-bit is also encouraged.

To install HMS-PrePro, place the contents of this folder anywhere on your computer.
The HMS-PrePro folder contains a toolbox that you can add to ArcToolbox or ArcCatalog.
