Abstract : A critical survey is given of studies conducted on optical parameters of natural formations. The author has shown that for purposes of aerial photography, the optical properties of natural formations can describe with adequate completeness their spectral coefficients of brightness (SCB). Data are given on the accuracy of determining the SCB of natural formations necessary for the contemporary state of art of aerial photography. The author examines the factors modifying the SCB values of natural formations. A survey is given of the instruments, plus an analysis of their suitability for determining the SCB under natural conditions. A conclusion is made to the effect that at the present time, the extent of our knowledge concerning the optical properties of natural formations is inadequate both from quantitative and geographic standpoints; the data available on the SCB lack the necessary generality. Recommendations are given on improving the study of optical parameters of natural formations.
