Check Files 2d DEM Z HR: Difference between revisions

TheThis _DEM_Z_HRfile contains a raster based on the sampled Sub-Grid Sampling (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 output set up, the _DEM_Z_HR will automatically be output as a check file instead of the <u>[[Check_Files_2d_DEM_Zmin | _DEM_Zmin]]</u>.<br>

Output grid formats currently supported by TUFLOW include GeoTIFF grids (.tif), binary grids (.flt) and ESRI ASCII grid format (.asc).

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>
