基于Skyline的流域河口生态安全评价三维场景实现技术

Realization of three-dimensional scene of ecological security evaluation in valley and estuary based on Skyline

在总结了地学可视化发展过程及目前三维可视化技术研究进展的基础上,针对大洋河流域河口的地理特征设计并实现了三维可视化场景,为流域河口生态安全评价三维演示系统的实现奠定了基础,并从地表模型的建立、建筑物模型的建立和虚拟场景的搭建三方面详细介绍了流域河口三维场景实现的具体方法。

Based on the development of geonomy visualization and three-dimensional visualization technology,the introduction on the way to build the three-dimensional scene in valley and estuary was done,in the light of its geographic situation.It will be a foundation for the realization of 3D valley and estuary ecological security evaluation demonstration system.It elaborated the specific method from three aspects,including the earth＇s surface model,building model and whole virtual scene.
