The direct HR output tends to have better resolution in comparison to the remapped results. Due to the additional stages of interpolation involved with the remapped output, there is potential to lose definition in the results particularly in areas with steep slopes.
==How to create a maximum grid for datasets without direct maximum output from a TUFLOW run?==
===Cumulative datasets===
For cumulative datasets without direct maximum output (e.g., cumulative infiltration, cumulative rainfall), ensure that the map output interval in the TCF matches the simulation end time (in seconds). The '''end time output is the maximum for cumulative datasets''', as it represents the cumulative results over the entire simulation duration.
===Non-cumulative datasets===
For non-cumulative datasets without direct maximum output (e.g. Froude number, rainfall rate etc):
*Adjust the Map Output Interval in the TCF to a smaller value to ensure temporal variations are captured.
*Specify XMDF for Map Output Format.
*Identify the output ID number of the desired dataset within the .xmdf file:
<pre>“C:\TUFLOW\Releases\res_to_res\res_to_res_w64.exe” -xnfo results.xmdf</pre>
*Extract maximum values using the [https://wiki.tuflow.com/RES_to_RES res_to_res] utility.
*Confirm the dataset’s output ID number in the resulting (maxmax).xmdf file:
<pre>“C:\TUFLOW\Releases\res_to_res\res_to_res_w64.exe” -xnfo (maxmax).xmdf</pre>
*Convert the resulting dataset to a preferred grid format for GIS use using the [https://wiki.tuflow.com/TUFLOW_to_GIS TUFLOW_to_GIS] utility.
:'''Note:''' For non-cumulative datasets, this method depends on the chosen map output intervals, and true maximums may not be captured if the intervals are too large.
