Visual Analysis of Spatial Data through Maps of Chorems

Résumé

Chorems were initially introduced by the geographer Brunet in 1986 to visually synthesize a territory and a set of phenomena concerning it. A recent collaboration among research institutions has adopted the chorem concept aiming at providing a new cartographic solution capable to support analysts’ work. Current results have illustrated how chorematic maps can be used to summarize the content of geographic databases and a system prototype has been specified to produce them in a semi-automatic way. In this paper we aim to demonstrate that chorems can be exploited to both catch a thematic global view of a territory and its phenomena, and investigate a single phenomenon by accessing data characterizing it. The proposal is based on Shneiderman’s mantra for designing human interfaces “Overview, zoom and filter, details on demand”, and an example is described to show how functionalities work.
