Abstract:The information of terrain shadow is an important subject when we study 3D visualization,terrain radiant correction of remote sensing image,calculation of solar radiation of mountainous areas,etc.This paper deals with the identification of the terrain shadow based on DEM,which the direct solar radiation creates.The terrain shadow includes umbra and drop shadow.The methods for identifying the two types of terrain shadow are presented in this paper.According to the methods,the terrain shadow image of Taibai M...
Keywords:Shadow  Umbra  Drop shadow  DEM
