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

| Gaia: | Chorems can be defined as representations of elementary structure of a geographic space or as schematized representations of territories, and as such 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 who needed an exhaustive knowledge of the territory under study, a clear-cut set of rules to decide what the salient phenomena are, and who had no problems to cartography them. Here we present a methodology based on spatial data mining, that both diminish the requirements in terms of starting knowledge, and provide a more rigorous approach to select the important features. |
