One of the major technics while distributing relational databases lies on the partitioning of the relations which is followed by allocation issues. The partitioning is computed through a query based approach organizing data vertically and/or horizontally. Even object oriented distributed databases are built in general on these principles. The aim of this paper is to show that as far as GIS are concerned, a structural modeling of objects may be obtained without taking care of queries asked or methods applied to the databases . The mechanism used requires a high order logic statements and processes a set of sites which ares components of a distributed GIS interacting in a global intelligent environment. The results are tested out in Urban planning sector.
