High Resolution (HR) Grid/Raster Map Outputs was first introduced in TUFLOW 2020-10-AB release. When an SGS model uses “SGS Approach == Method C”, the sampled elevations are retained at the end of the geometry processing. These sub-grid elevations include topography modifiers such as breaklines, and they allow a high-resolution elevation check file to be written and used for high resolution depth map outputs. Currently, ASC, FLT and TIF raster formats are supported.

To produce high-resolution output, add “HRASC”, “HRFLT” or “HRTIF” to the “Map Output Format ==” command, for example:
<font color="blue"><tt>Map Output Format </tt></font> <font color="red"><tt>== </tt></font> <font color="black"><tt>XMDF TIF HRTIF</tt></font>
At the moment, only water level and depth are supported as the High Resolution Output formats, i.e.:
<font color="blue"><tt>HRTIF Map Output Data Types </tt></font> <font color="red"><tt>== </tt></font> <font color="black"><tt>h d</tt></font>
The map output data types and output interval can be defined separately for the High Resolution Output formats. For example:
<font color="blue"><tt>Map Output Interval </tt></font> <font color="red"><tt>== </tt></font> <font color="black"><tt>600</tt></font> <font color="green"><tt> ! Sets all map output interval to 600 seconds</tt></font>
<font color="blue"><tt>HRTIF Map Output Interval </tt></font> <font color="red"><tt>== </tt></font> <font color="black"><tt>3600</tt></font> <font color="green"><tt> ! Sets high res map output interval to 3600 seconds</tt></font>
The output resolution for high resolution grid output is defined using the following .tcf command:
<font color="blue"><tt>HR Grid Output Cell Size </tt></font> <font color="red"><tt>== </tt></font> <font color="black"><tt>0.5</tt></font> <font color="green"><tt> ! m or ft</tt></font>
If this command is omitted, the default output resolution is set as the SGS sampling distance.
