A Research On The Information Obtaining And Processing System For Ground Visible Environment

With the development of geography information and information visualization , geography information can be displayed on computers. And the establishment of ground visible environment will advance the urban digitization.The technology of ground visible enviorment syncretizes hot technologies in information field today,3D GIS,GPS,RS,special database and information visualization etc.This paper includes some researches on ground information obtaining and processing based on the information of obtaining and processing on the ground visulization technology.This thesis raises a post process pseudorange differential GPS arithmetic based on multi-ephemerises and proves the conclusion,classifies the urban enviroment elements and designes a database structure.This thesis makes a city planning scheme,and programs a building modeling system by VC.NET and OPENGL.
