Line 3: Output grid formats currently supported by TUFLOW include GeoTIFF grids (.tif), binary grids (.flt) and ESRI ASCII grid format (.asc). The preferred format can be set in the TUFLOW Control File (.tcf) using: <font color="blue"><tt>Grid Format </tt></font> <font color="red"><tt>==</tt></font><tt> TIF \| FLT \| ASC</tt>. The default output format is TIF. All of these formats are widely recognised (QGIS, MapInfo, ArcMap, SMS etc). 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> The cell size (resolution) of the ~~_DEM_Zmin~~DEM_Zmin check file (and all raster outputs from TUFLOW) can be set with the .tcf command: <brfont color="blue"><tt>Grid Output Cell Size </tt></font> <font color="red"><tt>==</tt></font><tt> <grid_cell_size></tt>. If this command is not set, the resolution defaults to: * Half the smallest 2D cell size (TUFLOW Classic) ~~<font color="blue"><tt>Grid Output Cell Size </tt></font> <font color="red"><tt>==</tt></font><tt> <grid_cell_size></tt><br>~~ * Half the 2D cell size (TUFLOW HPC) * Smallest 2D cell size (TUFLOW HPC with Quadtree) 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, use the [[Check_Files_2d_zpt \| 2d_zpt]] check file, which is more suitable for viewing the values at individual zpts.<br>
