Fusion de données géoréférencées Aggregation of georeferenced data

This article deals with a method to describe and manage spatial knowledge. Each georeferenced data is considered as an information source, whose location and value are independently described. The method proposed in this paper uses the information sources to infer the value of any request zone . This method is able to treat imprecise or uncertain, qualitative and quantitative data. It can be applied whatever the spatial resolution of the available data sets. Our approach is based on fuzzy sets and possibility theory. The aggregation of information sources is provided by an aggregation operator based on the Choquet integral. An application of the method on a precision viticulture data set is also detailed.
