Introduction

The TUFLOW_to_GIS.exe is a utility available on the the TUFLOW website (http://www.tuflow.com/Downloads_Utilities.htm Download TUFLOW utilities]).

The utility can be used to convert TUFLOW outputs (.dat and .xmdf) into formats that can be imported into GIS packages such as MapInfo, ArcGIS and SAGA. For more details on the TUFLOW utility please see section 11.2 of the 2010 TUFLOW manual.

Running TUFLOW_to_GIS

Simply double clicking on the TUFLOW_to_GIS executable will bring up a DOS prompt that that gives you some instructions on running the utility.

The most common way to run the utility is from a batchfile. This allows the user to process multiple outputs at once.

Output Options

Gridded Data

The major output options are 3D grid in .asc format, which can be read into ArcGIS (requires Spatial Analyst), SAGA and MapInfo (requires Vertical Mapper or Encom Discover). This is specified with the flag -asc.

Point and Vector Data

Vector outputs can be written as either points or arrows. Scalar output can be written as points. These can currently be written out in MapInfo .mif format. The -mif flag is used to output in MapInfo format.
