Abstract :
Describes the first steps in the authors´ work towards using an airborne imaging spectrometer (AISA) as a source of information in an operational, large area forest inventory system. The necessary properties of algorithms for this kind of task are discussed, including handling of the atmospheric effects. An algorithm for automatic selection of spectral channels for estimation of forest parameters is presented and it is applied to AISA data from Southern Finland
