Abstract

Adopting Client/Server architecture, based on hypertext transfer protocol and oriented object method, and using such developing program tools as Visual C++, OpenGLand Active Template Library, the authors have developed a global virtual terrain application system. Database organization functions in the server as well as data transmission and real-time display mechanism are dealt with in this paper. Pyramid data structure and wallet analysis principles are introduced to simplify data. The problem as to how to construct highly efficient indexes and algorithms for displaying and operating 3D landscape on the browser is also discussed. Finally a test is made by using different levels of detail data.

Keywords Post-remote sensing application technology Geology exploration Development of method and technology Effect of geological application
