In numerous cases, the modelling of Geographical Information Systems (GIS) is a difficult task. This fact is partially due to the natural complexity of spatial types and invariants. Based on this observation, the present paper aims at specializing the Unified Modelling Language (UML) and its associated Object Constraint Language (OCL) in order to facilitate the design of GIS. A complete study of the proposed extensions will be presented as well as several in-depth experiments in the domain of agricultural information systems.
