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 [[Check_Files_2d_DEM_Zmin | _DEM_Zmin]].
