Un portail web pour rassembler et analyser des données spatiales hétérogènes sur l'économie sociale.

This research uses spatial datawarehouses and OLAP (OnLine Analytical Processing) to store and explore large spatial datasets in a user friendly web interface. Data can be filtered and drilled in interactive maps/charts (data exploration) and automatically summarized in reports about administrative entities in Belgium and France at different scale levels. Comparisons can be performed between Belgium and France despite important differences in data structures and semantics. This heterogeneous aspect implies an original management of data marts and data integration through ETL (Extract, Transform, Load) processings
