TheThis _DEM_ZMinfile contains a raster based on the minimum Sub-Grid Sampling (SGS) elevations. This file is only produced when running a model with SGS.<br>
<br>
Output grid formats currently supported by TUFLOW include the ESRI ASCII grid format (.asc), binary grids (.flt) and geodetic grids (.tif). 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 as TIF. The [[ASC_to_ASC#2023-03-AA_.28and_later.29 | asc_to_asc utility]] can be used to convert between ASC and TIF (in both directions).<br>▼
<br>
All of these formats are widely recognised (QGIS, MapInfo, ArcMap, SMS etc). The cell size of the _DEM_Zmin 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 each point the [[Check_Files_2d_zpt | 2d_zpt]] check file can be used. The _zpt_check file is more suited to viewing the values at individual zpts.<br>▼
