Check Files 2d DEM Zmin

This raster file contains the final minimum elevations 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.

Output grid formats currently supported by TUFLOW include the ESRI ASCII grid format (.asc), binary grids (.flt) and geodetic grids (.tif). The TCF command Grid Format == ASC or Grid Format == FLT or Grid Format == TIF can be used to set the preferred output format. The default output format as 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.
