摘  要:
对SPOT高分辨率卫星遥感图像的融合、增强、转值等进行处理,得到较清晰的建筑物阴影信息,然后结合Erdas中的专家分类系统,判断建筑物的阴影、阴面、阳面,并结合阴影和相应建筑物的数学关系计算出建筑物的高度信息,在矢量化的基础上通过Erdas的Virtual GIS模块建立贵阳市三维模型。

摘  要:
The methods of amalgamation,enhancement and rotation were used to deal with high resolution images of SPOT,so the clear shadow images were produced,the shadow was clarified with the expert classification including the shadow side of building,the sun side of the building and the mathematical formula were used to calculate the height of building.Based on the vector document three-dimensional model was built through Virtual GIS model of Erdas.
