This tool is designed for creating and modifying DTMs and performing a range of analyses such as map digitization and bathymetric interpolization. It may used for generating model inputs for several hydrologic, hydraulic and hydrodynamic models including EFDC_Explorer, HEC-HMS and HEC-RAS.


Some parameters that may be generated include drainage areas, SCS Curve Numbers (CN), slopes and flow lengths. Curve numbers are calculated for soils polygon coverage from a variety of sources. This software was developed by DSI and is customizable for project and client needs.
