Description:
An algorithm developed to map flooded areas
from synthetic aperture radar imagery is presented in this paper.
It is conceived to be inserted in the operational flood
management system of the Italian Civil Protection and can be
used in an almost automatic mode or in an interactive mode,
depending on the user’s needs. The approach is based on the
fuzzy logic that is used to integrate theoretical knowledge
about the radar return from inundated areas taken into account
by means of three electromagnetic scattering models,
with simple hydraulic considerations and contextual information.
This integration aims at allowing a user to cope with
situations, such as the presence of vegetation in the flooded
area, in which inundation mapping from satellite radars represents
a difficult task. The algorithm is designed to work
with radar data at L, C, and X frequency bands and employs
also ancillary data, such as a land cover map and a digital elevation
model. The flood mapping procedure is tested on an
inundation that occurred in Albania on January 2010 using
COSMO-SkyMed very high resolution X-band SAR data.
