基于海量数据的三维场景调度与展现
|
摘要
随着近年信息技术的迅速发展,通过卫星遥感等技术采集海量的高分辨率的遥感影像和地理高程数据信息,利用计算机图形学技术,将这些海量数据组织起来,建立一个趋于真实显示的数字地球模型成为现实。文章讨论了数字地球技术的应用需求,介绍了当前国内外数字地球技术的研究现状以及常见应用。同时介绍了实现多层空间数据集成融合与地形仿真的关键技术和设计思路,使得自主可控的数字地球引擎的设计和体系结构具有高灵活性和可扩展性。
With the rapid progress of information technology in recent years,it is important to establish a digital earth model based on massive data which includes high resolution remote sensing image and digital elevation information.This paper introduces the requirements,research status and widely applications of digital earth technology.At the same time,the paper introduces the key technology and design ideas of multi-spatial data and terrain imitation,making the system architecture and design of digital earth engine to become more flexible and extensible.
