La télédétection aéroportée pour la gestion des territoires forestiers de montagne

Abstract : A large part of the french forest resources is located in mountain regions. Increasing timber harvest would contribute to maintain economic activities in rural areas while providing additional renewable resources, but it is hampered by the complexity of forest stands and topography. Airborne lidar is a remote sensing technique that has been in constant expansion for the last twenty years. It is able to model the 3D structure of forests as well as topography, based on the scanning of the earth surface by laser pulses emitted at high frequency. When associated to field data, forest features (growing stock, accessibility) of interest to managers and users can be mapped at high resolution over large areas. This information allows the planning and implementation of forest sustainable management actions, aiming at fostering wood production while ensuring the provision of other services by forest ecosystems. The development of those applications however raises the issues of the availability of a relatively expensive data and of the conditions of dissemination and use of results among forest stakeholders.
