Use of spot satellite imagery to assess soil erosion caused by cyclone Bola in the major forests of gisborne-east coast, New Zealand

ABSTRACT
SPOT Satellite imagery was used to assess the effect of
a single storm in terms of the increase in bare ground
by comparing 1986 SPOT XS and 1988 SPOT PAN imagery for
the major forests of Mangatu. Tokomaru and Ruatoria of
the Gisborne East Coast. New Zealand DRAGON software was
used on a personal computer to enhance, register and
classify eleven selected sub-images, each of which
covered an area planted with Pinus radiata in one of
four different age classes.
