This thesis proposes a model based on the planar map notion. Data of the same plane level are modeled by several planar maps each of which corresponding to a class of semantics. These maps are independent and superposed. Modeling of data belonging to parallel planes is also allowed by planar maps superposing. Display and manipulation of data belonging to parallel planes are ensured thanks to a three-dimensional representation that is inspired by perspective techniques in draughtmanship domain. A hierarchical data structure offers the possibility to detail one zone of the plane (a face in planar map notion) by many planar maps corresponding to the different semantics. Furthermore, this model handles perfectly the semantic links that could lie abjects modeled in different planar maps. Hence, it preserves the whole meaning of the modeled scene. The proposed medel has been used to design a graphical interface within the scope of an european Esprit project MMI2* An ergonomie evaluation of that interface and refinements made in it as consequence of the evaluation are also presented in this thesis.
