Conception d’un système d’information géographique résilient pour l’environnement

Abstract : This paper presents the mapping between heterogeneous data sources as a solution for designing a resilient GIS for environment. From a case study conducted on Chizé environmental observatory, we summarize the difficulties encountered by biologists and ecologists experts when maintaining various environmental data acquisition devices and analyzing these data. In this example, crop rotation and wildlife data are recorded since 1994 in various spatiotemporal databases. We show how the implementation of a semantic mapping of these sources can solve challenges raised by the analysis and the maintenance of theses always evolving and heterogenous systems. In particular, the demonstration of the feasibility of such a system ismade, and we measure its ability to answer complex queries combining several data sources and the spatial and temporal dimensions.
