IRIS: A Tool to Support Data Analysis with Maps

The theme of our work is intelligent support to users in exploration of spatially referenced data. Under spatially referenced data we mean various thematic data (data on demography, economy, education, culture, history, etc.) referring to geographical objects or locations (countries, regions, cities and so on) rather than purely spatial data such as geometry of geographical objects and their relative positions with respect to other objects. Spatially referenced data cannot be effectively analyzed without representing them on maps. However, a number of different presentation techniques exist, and selection of proper techniques in accord with data characteristics is crucial for successful analysis. An improperly designed map can be unhelpful or even mislead the user into wrong conclusions.
