The _DEM_ZMin contains a raster based on the minimum SGS elevations. This file is only produced when running a model with SGS.
Output grid formats currently supported by TUFLOW include the geodetic grids (.tif), binary grids (.flt) and ESRI ASCII grid format (.asc). The TCF command Grid Format == TIF or Grid Format == FLT or Grid Format == ASC can be used to set the preferred output format. The default output format is TIF. The asc_to_asc utility can be used to convert between ASC and TIF (in both directions).
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:
Grid Output Cell Size == <cell size in metres or feet>>
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 2d_zpt check file can be used. The _zpt_check file is more suited to viewing the values at individual zpts.
