On the one hand, animals, and in particular herbivores, move in relation to the availability of natural resources (water and vegetation), that varies naturally in the year according to seasons (Valeix et al. 2007). On the other hand, when animals gather at specific places in depleting local resources, they influence space dynamics (Chamaillé-James et al. 2007). One major issue is to evaluate the impact caused by flows of individuals on space, what we call pressure due to animals on space. To begin, trajectories of individuals are drawn, enabling to visualize non only habitats but also movements. The aim of this contribution is to provide visual methods to identify attractive areas, where flows of individuals converge.

[Termes IGN] représentation cartographique 3DRésumé : (auteur) This paper presents our approach to improve the 3D-MRDB population techniques in the context of buildings (i.e. to define several geometric representations, different levels of details, of a geographical object). After having discussed our motivations, we present an overview of existing researches relating to the extraction of buildings’ geometries. A description of the multi-scale pattern concept, developed in our working group to support the extraction of simplified geometries, is also provided. We present afterwards our system approach to improve the detailed geometry extraction automation (through parametric models) while facilitating the extraction of simplified geometries (through multi-scale pattern). Our system architecture, implementing the Instance Driven SASS (Instance Driven Selection of Algorithms Setting and Sources) concept based on a priori knowledge is then described as well as the associated concepts. This semi-automatic approach requests the operator to introduce a priori knowledge; the sources, the algorithms and the parameters are then automatically selected according to the context. Finally, our methodology, aiming at implementing and validating our system, and the progress report of the project are described in the last part of this paper.
