Chorems are schematized representations of territories, and so they are a good example of data and geometric generalization processes. Until now, chorems have been produced manually by geographers using their own knowledge of the territory. So, the information generalization and summarization particularly in spatial data take place in this new international project launched in order to automatically discover spatial patterns and layout chorems by relying on a spatial database. After examining certain manuallyproduced chorems, guidelines are formulated. Then the architecture of a prototype system is presented based on a canonical database structure, a subsystem for spatial pattern discovery based on spatial data mining, a subsystem for chorem layout and a specialized language to represent chorems.
