=Remap Other Output Grids=
The utility can also remap extra grid files (e.g. a hazard output) to the resolution of the DEM file.
<tt>asc_to_asc.exe -remap -wl lowres_h.asc -dem DEM_highres.asc lowers_hazard.asc</tt>
This command reads in an extra grid 'lowers_hazard.asc' and remaps it to the finder DEM resolution.The figure below compares the original hazard output from the 10/20m SGS model and the remapped hazard output.<br>

overlays the remapped water depth on top of the 10/20m model water level output, and compared it to the original water depth output. As can be seen, smooth water depth along the gully and flood fringes is produced by the post process utility.<br>
