The TUFLOW_to_GIS.exe is a utility available on the the TUFLOW website <u>([http://www.tuflow.com/Tuflow%20Utilities.aspx Download TUFLOW utilities])</u>.
<br>
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, QGIS and SAGA
<br>
'''Note''' That as per the 2013 version of TUFLOW, TUFLOW can now write directly to the gridded formats (.asc and .flt). This avoids the need for a separate conversion step. This is outlined in the <u>[http://www.tuflow.com/Download/TUFLOW/Releases/2013-12/Doc/TUFLOW%20Release%20Notes.2013-12.pdf release notes]</u>.<br>
<br>
The output frequency and data types can now be specified independently for each data output format. An example is given below:<br>
<tt>Map Output Data Format == XMDF ASC <br>
XMDF Map Output Data Types == h v d MB1<br>
XMDF Map Output Interval == 300<br></tt>
ASC Map Output Data Types == h v d Z0<br>
ASC Map Output Interval == 0 <br>
In the example above, both .xmdf and .asc are written directly by TUFLOW. For the .xmdf output the water levels, velocity, depth and mass balance output are written every 300 seconds (5 minutes). For the .asc format the water levels, velocities, depths and hazard (velocity depth product) are written. These are written only for the maximum (ASC Map Output Interval == 0).
The TUFLOW to GIS utility can output to grid format and also MapInfo and Shapefile format. For the MapInfo and Shapefile format this can be either as points, or as arrows.
▲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, QGIS and SAGA. For more details on the TUFLOW utility please see section 11.2 of the 2010 TUFLOW manual.
