A user context approach for adaptive and distributed GIS

The research presented in this paper introduces a user context approach for collaborative and adaptive Geographical Information System (GIS). The proposed model is part of a framework based on a multi-dimensional contextual approach that combines user, geographical and device contexts. The spatial properties of the GIS components categorize different configurations as a support for the derivation of user groups. The interfaces and functionalities offered by the adaptive GIS are generalized within each group, and derived from the interface usages. The spatial behaviors that reflect user experiences within a group favor collaborative exchanges. A prototype applied to maritime navigation validates the approach and the algorithms developed.
