Abstract:By the way of quantity estimation of the satellite image,including the cloud/surface detachment,cloud classification,cloud top estimate etc,this paper can model the three-dimension of cloud by the estimated product.First of all,added the terrain,then distinguish the transparent and semi-transparent cloud by blend of the texture,and set the alpha as zero of the clear area,drawing the triangle grid by the cloud height estimate product and DEM,we model the three dimension cloud which can be consistent with the real cloud in the gross.
