4th Nordic Summer School
                      in Geographic Information Science
       3 - 7 August 2009, Gävle, Sweden
(in conjunction with the 3rd ICA workshop)
Intelligent Geographic Information Systems 

Vasily V. Popovich

As level of the GIS applications is rising and their inner logic becomes more complex the use of conventional programming languages in their development turns into a restraining factor. They urgently need means of intelligent support, such as rule-based systems, ontologies, multiagent systems and other artificial intelligence (AI) techniques, especially in the web applications. Intelligent GIS (IGIS) utilizes modern progress in the storage, presentation and geoinformation data processing.

The workshop will discuss a core of the IGIS technology that consists at least the three main parts: 1. Digital Object GEO - is multiplatform service-oriented technology for the centralized storage, selection, analysis and provision of geospatial information. 2. Digital Ontology Service - is a unified directory of information which is used to store the data needed to produce solutions to the problems faced by the user. It provides computer assisted formulation of the fundamental concepts and objectives of the knowledge domain and the relation between them. This component provides interaction not only between stored data but also data received from external sources. 3. Digital Intelligent Component - is an expert rule-based system, which provides overall information-consulting and functional support to the user, to interpret and use the complex scenarios presented to the user.

Two large scale applications on IGIS base also will be discussed as case studies. 1. Integrated Hydroacoustic Calculation System. It is a software application that integrates recent advances in the field of underwater acoustic calculations with the capabilities of GIS. 2. Complex of Radar Calculation Methods. The complex has been developed to provide radar zone modeling for the detection of low-flying, above-water objects by single or multiple radar systems, by adjusting for the effect of active and passive noise conditions and environmental parameters.
