The Method of Real-Time Viewshed Analysis on 3D Virtual Earth

Abstract:

Traditional viewshed analysis method is usually based on datum plane and local space area, which can not meet the accuracy requirement of the viewshed analysis on 3D Virtual Earth based on datum sphere and large space area. Regarding this, the article discussed a new method of viewshed analysis based on 3D datum sphere, and also realized the real-time visualization of the analysis result based on the 3D Virtual Earth system GeoGlobe. Finally it inspected and verified the validity of the method.
