View source for HEC-RAS to TUFLOW

=Introduction=
This page contains a brief introduction to the methods of converting HEC-RAS model inputs into a format which compatible with TUFLOW. If you have any suggestions to be included in these pages, please email <font color="blue"><u>support@tuflow.com</u></font>.<br>

= Model Geometry Conversion (SDF_to_GIS.exe) =
The SDF_to_GIS.exe utility converts HEC-RAS geometric data data into TUFLOW compatible GIS and csv input format. The utility outputs include:
<ol>
<li> Centerline location data in GIS format
<li> Cross-section locations in GIS format
<li> Cross-section data in csv format
</ol>
The GIS format type can be either *mif or *shp. Options are also available to automatically trim the processed cross-section GIS and csv data to the main channel region between defined levee markers.
The HEC-RAS model inputs need to be in SDF format (HEC-RAS export format), and must be geo-referenced using a real world projection.
== Input Processing (HEC-RAS) ==

== Example Utility Syntax (SDF_to_GIS.exe)==
The utility requires GIS projection information to correctly translate the spatial dataset from SDF format to *mif or *.shp format. This is done by including a projection or header file in the same folder directory as the SDF file. The utility will use the projection information from this file for the data conversion.
<ol>
<li> MIF Output: Projection.mif or Header.mif
<li> SHP Output: Projection.prf or Header.prj
</ol>
