Cartolis : vers un outil géomatique pour identifier et caractériser les segments de lisières forestières

Abstract : Forest edges are key components of rural landscapes because they influence ecological processes at the interface between habitats. There is a variability of forest edges, according to their physiognomy, orientation, history and topography, but few methods are available to identify these different types of edges and to map them at a large scale. We propose to identify edge segments based on morphological subdivision of forest boundaries. These segments are mapped and characterized by request on other spatial data. A procedure based on ArcGis tools, applied on the output from GUIDOS tools, is used to identify edge segments. We provide examples of edge segments descriptors obtained from a digital elevation model and from a landcover map. Results showed the feasibility of the automatic mapping of edge variability over a large scale. It opens new perspectives to build up a new tool for analyzing landscape dynamics and their effects on biodiversity.
