Abstract

The potential use of data from existing and planned earth resources satellites for the purpose of identification of surface materials is examined. Two different methods of the application of existing data to surface materials identification are discussed. The first method seeks to apply basic models of the physical processes involved in the reflection and emission of radiation. The second method utilizes "training sets" to empirically determine the signature of particular materials under given illumination conditions. Several difficulties complicate the application of the first method, and it is concluded that the present and planned Landsat spacecraft probably do not justify the use of the basic physical models. The method using training sets is judged useful with presently available data. Several examples using special multispectral combinations of Landsat data demonstrate the present potential of the existing earth resource satellite systems and suggest the increased potential promised by the higher spatial and spectral resolution of the next generation of earth resources satellite systems.
