This article mentions how satellite derived vegetation index maps are available to fire stations and fire managers. These maps show Very High Resolution Radiometer to determine the greenness of an area.
These maps allow fireman and people in the fire business to know the likelihood of a fire occurring and how much it will spread. This map shows how dry areas in Idaho and Montana are, versus how green they were or are.
The data is divided by manageable data sets, for example, regions. This allows one area to focus on their own problems. With the help of these maps fire managers may be able to stop fires from starting, or at the very least know where they might spring up.
