<li><tt>asc_to_asc.exe -out difference.asc -dif after_h.asc before_h.asc</tt><br>
Creates new grids comparing the differences in flood levels and extents for: "difference.asc" = "after_h.asc" - "before_h.asc"</li>
Secondary options (only one can be used):
*"-nowetdry" does not carry out a wet/dry test. If both cells are active a difference is calculated.
*"-change" calculates change even if one cell is null (wet / dry areas). Assumes a "dry" cell has a value of zero. Can be used to calculate depth change.
