    Luring tne past decade of intense studies and practic.i! work in the field of remote sensing, use has been made of multichannel radiometers in the visible and near infrared xegior'»n j r.ii different though fixed number of channels , at fixed olmrmo f >"•, km : t — ral bandwidth. Besides that, it was clear from the very beginning tnat for the different applications of remote sensing and l'or determining the real influence of the atmosphere, there exist, u Liferent sets of channels (in number and spectral bandwidth j in which optimum recognition is obtained of the investigated ne tuiai formations and objects. Tne precise determination of these n ib for certain regions of the Earth or for the purposes o1 a , iv n theme requires the collection of an enormous amount of spec tre J data with high spectral resolution about the reflected e J ee < > • >u g- netic radiation, as well as the setting up of a recognition .■> stein with complete classifier. There is sufficient clarity* at the present stage of development of the studies, about um mnyf sary sets of channels for a numher of themes, and ehe applioa t m.\d oi combined methods and devices make it possible to obtain solutions close to the optimum ones.
