GIS空间数据电子出版可视化技术研究

地理信息系统不仅发展成为一门成熟的技术科学 ,而且已成为一个新兴的产业 ,在测绘、地质矿产、农林水利、环境监测、区域开发等领域发挥越来越重要的作用。利用地球信息科学领域积累的大量的 GIS数据 ,进行其出版可视化技术研究与实践 ,不仅能够满足 GIS空间数据的出版要求 ,同时对于最大限度地利用 GIS数据资源、避免基础数据的重复投入和提高地图生产效率有着重要的现实意义。本文论述了地理空间数据的类型、关系、矢量数据结构及其在电子出版系统中共享的制约因素 ,讨论了 GIS空间数据在电子出版系统中可视化技术实现的基本方法 ,在实践的基础上提出了两种企业级解决方案。

A Study & Practice on Visualization Technology of GIS Data Publication

Geography Information system is gradually developed to a new industry not only a well thought out technology. It plays more and more important roles in survey, geology and minerals, agriculture and water ,conservancy monitoring of the environment and regional development. There are lots of data in domestic geo science. The study and practice on visualization technology of GIS space data publication can not only meets the demands of GIS space data publication ,but also has great significance on making full use of GIS data resource and enhancing mapproductivity. This paper discusses the types ,relationship,vector data structure of GIS space data,their shared and restricted factor in electronic publishing system,and the basic method for visualization technology in electronic publication of GIS space data. Two solutions are derived for enterprise based on practice.
