Computer-generated Visual Summaries of Spatial Databases: Chorems or not Chorems?

Résumé

Chorems can be defined as representations of elementary structure of a geographic space or as schematized representations of territories, and so they can represent a good candidate for generating visual summaries of spatial databases. Indeed for spatial decision-makers, it is more important to identify and map problems than facts. Until now, chorems were made manually by geographers based on the own knowledge of the territory and a rigorous reasoning. So, an international project was launched in order to automatically discover spatial patterns and layout chorems starting from spatial databases. After examining some manually-made chorems some guidelines were identified. Then the architecture of a prototype system is presented based on a canonical database structure, a subsystem for spatial patterns discovery based on spatial data mining, a subsystem for chorem layout, and a specialized language to represent chorems. But the results can be different from conventional chorems.
