Stand height is an optional spatial data theme that is used for computing spotting distances, wind reduction to midflame height, and crown fire characteristics. The values in the raster theme can be either integers or decimal values, meters or feet. The precision of the fire behavior calculations are limited to the nearest 1/10th meter or foot. Thus, if you have integer values and you want greater precision you should use the calculator features of your GIS to multiply the original height units by 10 and select meters*10 or feet*10 in the "Landscape (LCP) File Generation" dialog box. This conversion is optional for decimal stand height values.
