Statistics of Two-Dimensional Structure Elements of Mountainous Ranges (Mosaic Model) for Calculating Three-Dimensional Reflection Functions

摘要

Three-dimensional reflection functions were calculated in order to determine the albedo of an orographically partitioned terrain from satellite data. Quantities such as valley statistics and synthetic valley cross sections were determined by the analysis of two-dimensional structure elements of the terrain. These quantities allow the calculation of three-dimensional reflection functions. The methods of the computer program system for such an analysis are described. The application of the program system to two regions of the Alps yields acceptable results.
