is a zone of vegetation transition between two communities,
often resulting from a natural or anthropogenic environmental
gradient. In remotely sensed imagery, an ecotone may appear as
an edge, a boundary of mixed pixels or a zone of continuous
variation, depending on the spatial scale of the vegetation
communities and their transition zone in relation to the spatial
resolution of the imagery. Often in image classification, an
ecotone is either ignored if it falls within a width of one or
two pixels, or part of it may be mapped as a separate vegetation
community if it covers an area of several pixel widths. A soft
classification method, such as probability mapping, is
inherently appealing for mapping vegetation t
