Abstract

The digital elevated model is one of the main products of the geography information industry,is the foundation of landform emulation.This paper introduces the present development of three dimension technology,based on the reality of three dimensional visualization of OpenGL,and put forward the digital elevated model based on the three dimensional method,inquired the key technique problem in the process of realization,and pointed out the true foreground and the development trends of three dimensional visualization of OpenGL and landform emulation.
