Line 1:
This raster file contains the final material ID values in the model, it includes both 2D areas of the model and also 1D sections which utilise the 1D Water Level Line (1D mapping) functionality. If not using the material land use functionality (e.g. "<font color="blue"><tt>Set CnM </tt></font> <font color="red"><tt>==</tt></font><tt> 0.035</tt>"), this file may contain zero values. <br>
<br>
The output format of the raster grid will be either in the ESRII .asc (text) or .flt (binary) formats. The .tcf command "<font color="blue"><tt>Grid Format </tt></font> <font color="red"><tt>==</tt></font><tt> ASC</tt>" or "<font color="blue"><tt>Grid Format </tt></font> <font color="red"><tt>==</tt></font><tt> FLT</tt>" or "<font color="blue"><tt>Grid Format </tt></font> <font color="red"><tt>==</tt></font><tt> TIF</tt>" can be used to set the preferred output format. The default output format is TIF. The
<br>
Both of these formats are widely recognised (QGIS, MapInfo, ArcMap, SMS etc). The cell size of the DEM_M check file (and all raster outputs from TUFLOW) can be set with the .tcf command:<br>
"<font color="blue"><tt>Grid Output Cell Size </tt></font> <font color="red"><tt>==</tt></font><tt> <cell size in metres or feet></tt>"<br>
This raster is a north-south aligned raster and so minor interpolation is required to display the TUFLOW model on this grid. To view the exact values at the cell side points the [[Check_Files_2d_uvpt | 2d_uvpt]] check file can be used
<br>
The DEM_M check file can be styled in your GIS software and you can also perform grid calculation between simulations.
