*Outputs a classified grid, based on the cut off values and names in the "classifications.csv".<br>
:<tt>grid_to_grid.exe -classify classifications.csv results_VMax.tif</tt>
*If using vertical mapper the -grc option can be used to create the tifflt file in classified grid format,. inIn this format, rather than storing a numerical value when interrogating an area, a label is returned. This format is not recognised by ArcMap or QGIS. If using the grc option it is also possible to specify the desired RGB (red, green, blue) values for the output grid in the .csv file used for the classification. The RGB values should be specified in the 3-5th columns of the .csv file.<br>
