In the past, most LULC classifications have been created using
a pixel-based analysis of remotely sensed imagery. They used
either a supervised classification, unsupervised classification or
some combination (Enderle and Weih, 2005). These pixelbased
procedures
analyze
the spectral
properties
of
every
pixel
within
the
area
of
interest,
without
taking
into
account
the
spatial
or
contextual
information
related
to
the
pixel
of
interest.
With
the growing availability
of
higher
resolution
imagery,
this
spatial
information
could
be
used
to
produce
more
accurate
LULC
classifications
(De Jong
et al.,
2001;
Dwivedi
et al.,
2004).
