Towards Visual Summaries of Geographic Databases Based on Chorems

Robert Laurini

Résumé

For many applications, it is very important to get an overview of database contents; and in the case of geographic database, a visual summary can be very helpful for a decision-maker or for any person in charge of a territory. To get such a visual summary, a two-step process is built, first a phase of spatial data mining process extracts geographic knowledge, and a second phase visualizes it by means of chorems – which can be defined as sche-matized representations of territory. In other words, semantic generaliza-tion must be followed by geographic generalization. The scope of this pa-per is to present the last results of an international project.
