ABSTRACT

Paper describes in the first part the role of GIS in relation to decision-making and expert
systems, and its key elements. The second part describes our solution - an expert system
for evaluation of ecological stability and function of the landscape, which is based on
ArcGIS products and EMDS. Expert systems are computer programmes able to
simulate actions of an expert in a particular field when solving complicated tasks. They
are considered a sub-category of knowledge-bases systems. Spatial Decision Support
Systems are closely related to knowledge-based and expert systems whose creation was
possible due to artificial intelligence. Generally it is credited two basic roles in the
process of decision support: a) GIS is used for better decision support, because it helps
to collect, organize, analyse and properly visualize data that the user uses to solve the
problem. The decision on the appropriateness of solutions can be used modelling
alternative scenarios and then compare their critical parameters, b) GIS is widely used
in solving specific SDSS problems, which are geared to location and allocation
problems and highly applicable in the event of network analysis. For the application of
GIS in the SDSS it is specific that, in addition to building a data structure, which is the
primary reason for deployment, significantly applied and specific methods for
determining their own GIS technology. The designed expert system enables a
multidisciplinary view of a landscape being assessed from the four given viewpoints by
the chosen methodologies. The used methods of assessment have been known for some
time and occasionally used for GIS. The expert system is beneficial for these two
aspects: i) determining all four relations from minimum consistent data at the same
time, ii) formalised marking of reclassifying, assigning coefficients and ascribing
weights to the factors. Thanks to the documented methodologies for data preparation,
development of particular dependency networks and assessment procedure in EMDS,
the expert system can be also used for other areas of interest.
