Knowledge-based support for visual exploration of spatial data

The knowledge-based system IRIS is designed to help users in analysis of spatially referenced statistical data. For this purpose the system provides the user with automatically built thematic maps presenting the data visually. The process of map design is governed by the domain-independent visualisation knowledge base. The user receives the opportunity to concentrate on data exploration instead of the process of planning and building data presentations. Implementation of the interface part of the system in Java language allows to run the system in the World Wide Web (WWW).
