ABSTRACT
The improvement of any software
package is mostly aimed at reducing the
average time required to complete a typical task.
There are two ways to achieve this:
* by improving the algorithm used in the
software package,
* by transferring some functions which
are performed by an operator to the software
package.
The topic of the paper is to present some
suggested improvements in GIS software which
have been achieved through an implementation
of procedures which result in the system having
a measure of quasi-intelligence. The procedures
were implemented into an experimental GIS
which has been developed for the purpose of
testing procedures only. The concept of the
procedures is based on some ideas originating
from cybernetics, information and system
theories. However, the software package is still
in a development stage and requires further
improvements but it shows that it is more
effective and user-friendly than traditional
solutions of GIS software.
Key words: G.I.S. Software, Artificial
Intelligence, Data base.
1. GENERAL REMARKS
The human environment is filled with
various physical objects such as houses, people,
animals, plants, clouds etc. The geographical
environment can be considered as a certain
subspace of this environment. The objects, which
exist within this subspace create different
structures, for instance geological,
topographical, urban, legal and others. These
structures (organisations) are the subject of
research to identify rules which determine the
principles of their creation. This procedure is
necessary as we attempt to describe how human
activity in the geographical environment could
become more responsible and economically
optimal. However, before we start to identify
these rules, we have to prepare a comprehensive
list of the objects which exist in the geographical
environment. Geodesy and mapping are the
sciences which provide methodology and
technology for the preparation of the list. The
map is a traditional product of this process of
collection and storage of all information about
the geographical environment. The latest
developments in mapping have resulted in the
GIS, which apart from providing storage of
information, is equipped with tools to extract and
present certain objects of the environment
individually or in combination with others,
which are of interest to particular users.
The concept of an Information System
has its " ideological " origins in the pioneering
works of Norbert Wiener on cybernetics
(Wiener 1948), of Claudie Shannon on
information theory (Shannon 1948) and the
subsequently developed system theory (Director
1971). Information handling, feedback,
adaptation of the system are the central terms
used in these theories. These terms, however,
with slightly different meanings, are being used
in the field of Information Systems. These
sciences, principally cybernetics, aim to replace
human activities by machines, such as robots,
and are even extended to the thinking process
and intelligence itself.
Taking into account the "ideological
connection" between Information Systems and
cybernetics, this paper will concentrate on the
possibilities and consequences of creating such
an Information System, which in its operation
would perform intelligently, similarly to the
cybernetic tortoise, which keeps following the
source of light. The problem of the
understanding of intelligence will be discussed
first of all.
A definition of intelligence which is
acceptable to everyone, will probably never be
formulated. A review of many attempts at a
definition of intelligence is given by Simons
(Simons 1984). The reason for this is simply that
an observer who has never viewed the outside of
a home, cannot describe the outside, if he/she is
positioned inside. If somebody does go outside
the house and returns to relate what he/she has
seen, the person inside would not understand the
story. The description of intelligence is a
similar problem: it depends on the intelligence
itself, and for this reason a perfect definition of
