Line 1: <ol> =Introduction= asc_to_asc.exe is a utility that can be used ~~for~~to ~~generating~~perform ~~the~~a ~~difference~~range ~~between~~of ~~two~~operations on gridded files.~~asc~~ ( The input grids can be either ESRI ASCII grid (.asc) ~~files~~or binary float grids (.flt), both of which can be input and output from TUFLOW.<br> This utility is useful for comparing and processing TUFLOW outputs from different .2dm meshes, which can't be compared with the <u>[[~~DAT_to_DAT~~RES_to_RES\| ~~dat_to_dat~~res_to_res.exe]]</u>.<br> ~~The input grids are generally processed using the TUFLOW_to_GIS utility described <u>[[TUFLOW_to_GIS\|here]]</u> or from GIS packages.~~ For some options (such as processing maximums or differences) the input (.asc or .flt) files must be of the same row/column dimensions.<br> The inputs can be a combination of .asc and .flt grids and the -asc or -flt options can be used to set the output type. =Operations= ==Convert== '''"-conv"'''<br> Converts between .flt and .asc format. For this operation the output file type is based on the input, for an input .asc file the output will be in .flt format. Example:<br> <li><tt>asc_to_asc.exe -conv .flt</tt><br> Converts all .flt grids to .asc format. <br> <li><tt>asc_to_asc.exe -conv DEM_M01.asc</tt><br> Converts the file "DEM_M01.asc" for .flt format. ==Maximum== '''"-max"'''<br> Line 86 ⟶ 95: <li><tt>asc_to_asc.exe -brkline 2d_zsh_breaklines_L.shp DEM.asc</tt><br> ==Fuzzy Map== '''"-fuzzy <input grids>"'''<br> This feature was added to the 2014-03-AB version of the utility.<br> A fuzzy map can be used when comparing a large number of simulations.<br> For each input grid (or scenario) the grid is classed as either 1 if the results grid is wet or 0 if dry. The total score for each grid cell is is calculated and then divided by the total number of input grids. A value of 1 indicates that the cell was wet in each simulation a value of 0 is dry in all simulations. Grids with a value of 0.5 are most sensitive.<br> This can be useful for quantifying the sensitivity of the model to parameters.<br> Example:<br> <li><tt>asc_to_asc.exe -fuzzy _d_Max.flt</tt><br> This uses the wildcard (*), to create a fuzzy map from all maximum depth grids in the directory. =Other Options (switches)= A list of the general switches is provided in the table below, these are available for all operations listed above:<br>
