GenGHIS. Un outil de modélisation spatio-temporelle pour le suivi historique des risques naturels

Nowadays, the management of natural relies on spatio-temporal but also multimedia information. Designing an Information System dedicated to Natural Risks (ISNR) requires a specific approach for modelling, querying, and visualizing such kind of information. Although the needs for developing these Geographical Information Systems are information. Although the needs for developing these Geographical Information Systems are increasing, few tools exit. We present here GenGHIS a tool for designing and developing ISNR. We describe the modelling approach as well as the conceptual kernel common to each ISNR. We illustrate our approach by presenting an application developed with GenGHIS and dedicated to the avalanche risks.
