GIS-BASED COMPUTATION OF SOLAR RADIAITON ON SLOPE SURFACE
地理信息系统支持下的坡面太阳辐射计算

A comfuting model of Solar radiation in mountain area based on Geographic Information System(GIS) is introduced in this paper .Radiation on sloping surface is computed by using digital spatial data of solar radiation on horizontal surface and Digital Terrain Model, composed of digital data of elevation, Slope gradient and aspect as input data.
