The paper focuses on the problem of 3D data modeling within Geographical Information Systems (GIS) . The approach presented here brings a solution to manage the diversity and the complexity of 3D data in a Geographical Information System. Our approach is not to use one unique model but 2 levels of modeling in order to describe the whole 3D scene. The first level uses a 3D topology composed of nodes, edges, and faces. A volume is defined by its shell. This model insures object’s consistency… CONTINUE READING
