can also be used for the detection and separation of the
class settlement.
The described functions of GEOAIDA are easy to use, the
operators can solve complex grouping tasks by use of a
functional language.
4 CONCLUSIONS
The very flexible knowledge based interpretation system
GEOAIDA was introduced. GEOAIDA is based on the
functionality of existing image processing operators that
can be used context specific and can be initialized problem
specific. The arised hypothesis of the first step are grouped
and valued by use of context knowledge in the second step.
This approach enables a decision between alternative inter-
pretations and provides consistent results. The results can
be used as basis for maps or for geographic information
systems. The further development of GEOAIDA should
allow the multi-temporal interpretation of remote sensing
data. The detection of alteration can be used for environ-
mental studies, the development of urban areas and for ex-
amination of natural disasters.
