Indicatrices of the earth's surface reflection from Landsat MSS data.
A method of obtaining an indicatrix or a scattering diagram of the earth's surface is developed. When we regard the earth's surface as a kind of irregular surface, the indicatrix of scattered radiation is a way of effective representation of its surface roughness. The indicatrices of radiation over the sands of a seashore, a downtown area of Tokyo, and some of its suburban areas are obtained from Landsat MSS data. The radiant intensity decreases within the range of 32 degrees to 65 degrees of scattering angles in accordance with the degree of urbanization. Experimental results obtained by a remote sensing simulator are compared with those of Landsat MSS data analysis.
