The _DEM_Z_HR contains a raster based on the sampled SGS elevations. This file is only produced when running a model with SGS that also has high resolution outputs. If a model has high resolution outputs the _DEM_Z_HR will automatically be output instead of the _DEM_Zmin.
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, Grid Format == FLT or Grid Format == ASC can be used to set the preferred output format. The default output format is TIF. All of these formats are widely recognised (QGIS, MapInfo, ArcMap, SMS etc). The asc_to_asc utility can be used to convert between ASC and TIF (in both directions).
As with the other high resolution outputs, the resolution of the _DEM_Z_HR check file is determined based on the SGS sampled distance. For example, if the SGS Sample Target Distance == 0.5, the DEM_Z_HR will be at 0.5m resolution.
This raster is a north-south aligned raster and so minor interpolation is required to display the TUFLOW model on this grid.
