Identification des grandes trouées dans les forêts de montagne à partir de modèles photogrammétriques

Abstract : Many mountain forests are today composed of old tree stands. In order to replace those stands, the Forest Management Guide for the Alps proposes a management using forest gaps. This technique is quite new for the Alps and raise questions regarding the follow-up of those gaps and especially the time needed for regeneration. Photogrammetry seems to be a promising technique in order to answer those questions and the aerial photographic took by the National Geographic Institute allow us to study larger areas. Through the production of Digital Elevation Model (DEM) and Canopy Height Model (CHM) and their analyses with two different approaches, it has been possible de create a methodology allowing the identification of gaps areas and occasionally the identification of individual gaps.
