Methods of computer geoinformation modelling underlie designing,
creation and use of the various integrated information-cartographical models.
Among the latest it is necessary to underline special models: cartographic
multimedia. Specific communication properties of
cartographic multimedia are based on the fact that they display a complex
geodata and others auxiliary component in the form of a
polymodal information image
for the researched phenomena and processes. Thus an
information basis
of cartographical multimedia are geoimages of three
types: the map (plan), definitely processed space
pictures and so-called
virtual maps - three-dimensional
dynamic cartographic models. Text materials and tables, photos, animated
graphics, video and music are also an integral part of cartographic
multimedia.
The technique of cartographical multimedia creation should comprise
a number of general principles which can be presented in the following form:
·
Creation of
cartographic multimedia should be based on the certain conceptual positions determining the
purpose of its creation, methods of designing and character of use;
· A technological basis of
cartographical multimedia creation are GIS-TECHNOLOGIES and specialized
computer programs which provide the complex of actions on input, processing and
presentation of various
data;
· The technique of
cartographical multimedia creation is based on the semantic approach to the analysis of the information and optimization of
hypercommunications between components of multimedia geoinformation model.
· Creation of
cartographic multimedia should be made according to their optimization
concerning engineering and psychological principles of information modelling in system "person-machine" and
also principles of reliability of information modelling in system «person-geoinformation mapping»;
· According to the basic
methodological approach to designing cartographic multimedia it is necessary to
use methodology of atlas mapping,
and electronic complex mapping, as the optimal form of representing cartographical information,
with required accuracy and reliability.
The specified principles of cartographical multimedia
creation are approved,
in
particular, at creation of the local multimedia atlas “RUSSIA ON A THESHOLD OF
THE THIRD MILLENIUM (the European North of Russia)” and multimedia presentation
of the atlas “SPACE METHOD OF GEOECOLOGY “.
