Abstract

High resolution satellite data were used to assess the potential of satellite remote sensing for a better knowledge of the spatial distribution of the forest resources and a better management of this potential energetic resource. The mapping of the biomass forestry can be organized into two phases. The first phase is the pre-processing of the ground-established data and the satellite data. Then both types of data are processed with relevance to forestry. Using an image of July 1985, forests have been mapped for two classes of stand: coppice or timber, and for the three major present species : oak, beech and coniferous. The same analysis was applied to an image of October 1985. The dynamics of the spectral reflectances are greater in July than in October so that classification is more precise with the July data. These satellite data did not bring out any accurate information about the volume of standing wood even for low volume. About fifteen models for the reconstruction of the volume of standing wood from satellite data were tested against ground measurements. The error was very large due to the asymptotic response of the reflected radiance as biomass increases.
