TUFLOW Remapping: Difference between revisions

 

In TUFLOW, the depth output is interpolated from the depths at the nearest cell centre and cell corners surrounding the output grid. Because TUFLOW doesn't store the underlying high resolution DEM values at the moment, the interpolated depth may not perfectly represent the actual depth as illustrated in the figure below. <br>

While we are developing high resolution SGS output in the future release to address this issue, we have also added a new functionality in the [[ASC_to_ASC|ASC_to_ASC]] utility to 'remap' a water level grid to a finer DEM grid. This page introduce how to use the [[ASC_to_ASC|ASC_to_ASC]] remap function, and also discuss the limitation of the method.
