=Introduction=
A plugin for QGIS has been developed (by Lutra Consulting) which allows the TUFLOW binary format (.dat or .xmdf) results to be viewed in QGIS without the need to convert these into shapefile or raster format. Installation instruction are available on the [http://www.lutraconsulting.co.uk/resourcesproducts/crayfish/wiki Crayfish page on the Lutra website].
 
The plugin has a number of limitations as outlined on the page above, including support for 2D only model results (no 1D mapping).
 
To view models with 1D WLL mapping (which is introduced in Module 04) raster and vector layers will need to be used, this method is outlined in the following page <u>[[View_Results_in_QGIS | view Results in QGIS using shapefiles / raster layers]]</u>.
=Method=
<ol>
<li>Ensure that the Crayfish plugin has been installed ([http://www.lutraconsulting.co.uk/resourcesproducts/crayfish/wiki installation instructions are on the Crayfish homepage]).</li>
<li>Ensure QGIS is open.</li>
<li>Open a TUFLOW layer by selecting '''Plugins >> Crayfish >> Add Crayfish Layer''' from the menu</li>
Line 29 ⟶ 26:
<li>Please feel free to experiment with the visualisation options and get a feel for your TUFLOW results. Do the results look sensible? What happens at the road crossings?
</ol>
 
=Conclusion=
We have covered the basics of viewing 2D TUFLOW results in QGIS. Please return to the tutorial model, module 1. In the next step we review the performance of the TUFLOW model (warnings, checks and mass balance), to return please click <u>[[Tutorial_Module01Tutorial_Module01_Archive#Reviewing_Model_Performance | here]]</u>
