Title
Proceedings of the Symposium on Global and Environmental Monitoring

It was impossible to use the results that
were obtained from Landsat-MSS 1972 and
set them off against 1985 because the
image of 1972 was coverd in some places
by clouds.
On the basis of the results achived by
the evaluation of landsat imagery, it
was possible to come to a decision as a
regard that the use of landsat imagery
for the monitoring and survey of the
forest decline is possible. It can be
concluded that it was possible, for
exampel , to identify and quantify forest
decline for three damage levels in the
test site St. Blasien/Schluchsee FRG (D
0-1; D2,D3, healthy/slightly damaged,
damaged, severely damaged stands) on the
TM data images. Furthermore it was even
possible to quantify the damage develop
ment through a one year period. This has
been confirmed with the field assessment
that has been done by the forest services
of this test site at St.Blasien .
A practical method for damage assessment,
mapping and monitoring for such a large
forest area as the test site at Erzge
birge, can not be done rapidly without
the use of Landsat data . It was possible
to distinguish between the determined
damage levels for the actual forest
situation on Landsat images. With the
involvement of old landsat images in the
evaluation one can estimate the change in
the forest area (clear cut area and in-
creasement of non forest zone) as well as
the change in the forest current situa
tion regarding, damage levels in the test
site at the Erzgebirge region.
