=Creating a TUFLOW Geometry Control File from MIKE21=
This section discusses how to extract data from a MIKE model to populate the TUFLOW Geometry Control file (TGC). The TGC file defines the:
* Terrain elevation
* Manning's
* Model domain
* Active cells
==Converting Terrain==
Like TUFLOW, MIKE uses a grid file to define the underlying terrain. MIKE uses its own grid format (.dsf2) as well as a local coordinate system. For these reasons, it needs to be converted into a format that TUFLOW can read as well as an absolute coordinate system.<br>The terrain dfs2 grid can be converted through the MIKE Zero toolbox. This can be done through the following steps:
<ol>
<li> Open the MIKE Zero program
<li> From the start page select <b>File</b> >> <b>New</b> >> <b>File</b>
<li> Under the <b>GIS</b> dropdown, double click <b>MIKE2GRD</b>
<li> Work through the steps being careful to specify an appropriate projection
<li> Before clicking <b>Finish</b>, ensure you have clicked <b>Execute</b> to run the conversion
<li> This should produce an ascii file that can be directly read by TUFLOW
</ol>
Unlike TUFLOW, the grid cell size of the model in MIKE is determined directly by the input grid file. For more discussion on grid cell size and the differences in how MIKE and TUFLOW handle the underlying terrain please see the discussion section at the bottom of the page.<br><br>''Note: After grid conversion, it is important to perform checks that the ascii grid has converted properly. This is best done in your preferred GIS package. ''
