Abstract In this paper authors introduce the concept of bidirectional reflectance and its relation to 3-D spatial structure of ground objects. It is suggested to develop appropriate BRDF modes for various kinds of earth surface along with the process to set up a high spectral resolution data base for their signature. Otherwise, it is pointed:out, the costly data base can hardly deal with the great diversity of natural scene in composition and structure. Also the author gives a revise to Strahler-Jupp model and introduce the new progress of bidirectional reflectance measurement.
