Hotspot lists and vector images are very small data files that can be transmitted quickly over narrow bandwidths such as those of satellite or cell phones. So images can get where they need to be in the shortest time possible.
General vector maps represent either the fire front or the full extent of the fire. Hotspot vector maps go a step further by indicating the precise location of hot spots near the fire front. By providing numeric notations calibrated with the intensity of the hot spots, crews can instantly refer to precise locations and attack the most dangerous areas first.
The locations of hot spots may also be indicated by geographic coordinates
and provided in a simple text
file format which can be quickly transmitted directly to field crews on
the ground equipped with GPS.
Hot spots ahead of the fire front indicate new areas of fire spread while hot spots behind the fire front must be controlled by ground crews to ensure that the fire is extinguished.
