== Converting to Arrows ==
To output to vectors file specify either a MapInfo "-mif" or Arc shapefiles ("-shp") output type and the "-vector" option. This will create a vector dataset, with the vectors stored as polygon objects.<br>
The size of the vectors can be controlled with the scale factor ("-sf") switch.
'''NOTE:''' The input .dat file or dataset type must be a vector dataset, such as velocity or unit flow.<br>
* Convert output time 2 to a MapInfo vector file at cell corners:<br>
<li><tt>TUFLOW_to_GIS.exe -mif -vector -b -t2 M01_5m_003_V.dat</tt></li>
<u>Description:</u> Convert to a MapInfo format ("-mif"), using vector outputs ("-vector"), using batch mode ("-b") and converting at time 2 hours ("-t2") for the velocity results '''M01_5m_003_V.dat'''.<br>
* Convert output time 2 to a MapInfo vector file at cell corners:<br>
<li><tt>TUFLOW_to_GIS.exe -mif -vector -sf0.5 -b -t2 M01_5m_003_V.dat</tt></li>
<u>Description:</u> As above with a scale factor of 0.5, so that the arrows will be half the length.<br>
* Convert output time 2 to a ArcGIS shapefile on a regular grid of 2m spacing:<br>
<li><tt>TUFLOW_to_GIS.exe -mif -vector -grid2 -b -t2 M01_5m_003_q.dat</tt></li>
<u>Description:</u> Convert to a ArcGIS shapefile ("-shp"), using vector outputs ("-vector") on a regular 2 metre grid ("-grid2") using batch mode ("-b") and converting at time 2 hours ("-t2") for the unit flow results '''M01_5m_003_q.dat'''.<br>
