The Method Of Extracting Height Of Building In A Large Scope

In this paper, it utilizes a few of stereo images, a lot of a single aerial images and the digital topographic map of the corresponding regions. We extract the height of building in the large scope by ERDAS and the effective building classification. Experiments proved that this method is little of work and easy for processing, it can be utilized in many fields. And it is useful to compute the urban built-up volume ratio, the land use type, the 3D reconstruction and so on.
