I - PRE-FIRE PLANNING AND MANAGEMENT
2 - Methodological Approach and results
The knowledge-based system we developed for fire susceptibility assessment
and fire recovery monitoring is mainly based on the use satellite time
series. In particular, the analysis of the MODIS data set 1999 to 2008
(available free of charge from NASA web site) provides reliable information
for the characterization of vegetation variations at different temporal and
spatial scales. This is crucial for (i) fire susceptibility and (ii) vegetation
fire recovery.
2.1 - Fire susceptibility assessment
The assessment of fire susceptibility is performed (as described in Lanorte
et al., 2009 in this book) integrating fuel property (type and loading) with
Greenness and fuel moisture daily maps. Fuel property is obtained from
Landsat TM data processed using supervised classification techniques and
spectral analysis methodologies performed at sub-pixel level. Using Landsat
TM images we mapped: (i) Vegetation type, (ii) Fuel type (Prometheus system),
(iii) Fuel model (NFFL system), (iv) Fuel load.
Figure 1 - Study area and fuel types.
The analysis was performed in the Capitanata land (Apulia region -
Southern of Italy) which is shown in figure 1. The estimation of fire susceptibility
was performed as in the case of Basilicata (FIRE-SAT) using
Landsat TM for fuel type mapping and MODIS for fuel greenness and moisture
estimation. Figures 2 show fire danger maps for February, May, July,
and October 2007 respectively.
