Abstract

Attempts to map different tropical forest types on a continental scale had varying success. Remotely sensed reflectance from forest canopies responds not only, or even primarily, to the species composition, but to a large number of factors, including soil type, forest structure, shadows and penology. This paper describes how detailed field data from sites in Bolivia are being used to develop and improve methods of tropical forest mapping from small scale satellite imagery. The paper presents preliminary work towards a novel procedure which characterizes canopy roughness from observations of forest structure and classifies imagery into canopy roughness classes by establishing a link between the shadow pattern information in the imagery and the canopy roughness of the forests. The inversion of the procedure will subsequently provide a means to extract forest structure information from satellite imagery and to generate improved maps of the tropical forest zone.
