Instantaneous fire activity can be recorded and viewed for all areas within the fire area using this feature. You must be doing your simulation with Post-Frontal Combustion enabled. The combustion maps show in raster format the rates of heat release, fuel consumption, and smoke production spatially at the time the simulation exists. A series of these maps would show the pattern of changing fire activity across the landscapes. Non-spatial post-frontal combustion data can also be accessed by graphs and data tables.
This command displays the "Combustion Maps" dialog box with eight different raster output maps available for the current time step. The simulation should be suspended when selecting this command. Only one map at a time can be selected, but you can click the Output > Combustion Maps command as many time as you wish.
Use the Output File Name button to assign a descriptive name to each map. All eight maps use the .ASC extension so make sure the file name contains the type of map and the time step when created.
Selecting the Coverage Within Viewport Only checkbox saves only the data from the current view port. Clearing this checkbox saves data for the entire landscape regardless of the view port extent.
The output resolution (or cell size) of the output map can match that of the current Landscape (.LCP) File by selecting the Native LCP Resolution radio button. Or selecting the Custom Resolution radio button allows you to enter a cell size in the text box.
Click the OK button and a raster map legend appears in the "Simulation Legend" window. Select the 2D or 3D checkbox to display the raster map in the appropriate "Landscape" window.
The above raster map is the default Fuel Weight Loss Rate map. Remember this is a map of a rate, the units are tons/acre/min. Notice the center, where combustion is complete, does not have any values.
Colors and display options are controlled with the Simulation Legend functions.
