You draw a rectangle on the map using the Landscape Extent icon on the Situation Assessment map. Since you should only be concerned with fire behavior characteristics or fire spread for a short time, you do not need to draw a large analysis area. Typically, an extent of 5-6 miles per side should suffice. If you run your STFB analysis and it seems too small, you can always re-draw the landscape extent. Making your landscape extent too large will slow the process time and tie up server time, thereby delaying other’s analyses. ———– Last updated on 11/23/2010 4:41:26 PM.
