Forest fires are a major environmental issue, creating economical and
ecological damage while endangering human lives. Fast detection is a key element
for controlling such phenomenon. To achieve this, one alternative is to use
automatic tools based on local sensors, such as provided by meteorological stations.
In effect, meteorological conditions (e.g. temperature, wind) are known to
influence forest fires and several fire indexes, such as the forest Fire Weather Index
(FWI), use such data. In this work, we explore a Data Mining (DM) approach
to predict the burned area of forest fires. Five different DM techniques, e.g. Support
Vector Machines (SVM) and Random Forests, and four distinct feature selection
setups (using spatial, temporal, FWI components and weather attributes),
were tested on recent real-world data collected from the northeast region of Portugal.
The best configuration uses a SVM and four meteorological inputs (i.e.
temperature, relative humidity, rain and wind) and it is capable of predicting the
burned area of small fires, which are more frequent. Such knowledge is particularly
useful for improving firefighting resource management (e.g. prioritizing
targets for air tankers and ground crews).
