The forest fires are one of the natural disasters that have a great impact, so much
socially as economically and environmental: they destroy an economic good, the wood,
affect to the climatic change when emitting enormous amounts of CO2 to the
atmosphere, they attack the biodiversity, destroying the wild life, facilitate the erosion
of burned soils, annul the emission of O2 of the forests, affect the landscape etc.

Remote sensing is a suitable tool to fight against this natural disaster in the four phases
of its development: before of the fire, allowing locating the areas of maximum risk to
concentrate in them means of fire fighting. During the fire, allowing to detect the “hot
spots” location and to know its characteristics: temperature of the fire, released power,
burning area etc. These are very important data for a suitable management of the fire
fighting. Just after the fire the burned area can be known and even the damage produced
in her, and finally, it is possible to make a pursuit of the recovery of the vegetation after
the fire.

In this presentation the different uses of remote sensing in these four aspects of forest
fires management are shown, displaying the results that are obtained using the AVHRR-
NOAA, FENG Yung, SEVIRI-MSG, MODIS, AATSR, ASAR and MERIS sensors.
