Abstract
The analysis of information obtained with the Multispectral Scanning System of the ERTS-1 satellite in the form of images of the earth's surface (Northern California) in four spectral regions (“channels”) is presented. The problem of optimal choice of channels to obtain multispectral images of natural materials from space is discussed. On the basis of the analysis of calculations of the entropy of spectral intervals and observation conditions of the greatest spectral contrasts of natural materials, the following spectral intervals in the 0.4–1.0 μm wavelength region have been suggested as most informative: 0.54–0.56, 0.66–0.68, and 0.78–0.82 μm.
