The swmm_to_gis.exe utility converts EPA SWMM files (.inp) to TUFLOW compatible GIS (mif and shp) format. The utility outputs include:

Utility Execution
The utility requires GIS projection information to correctly translate the SWMM file (.inp) from format to *mif or *.shp format. This is done by including either a projection or header file in the same folder directory as the batch file. The utility will use the projection information from this file for the data conversion.
