Abstract Internet as GIS provides a new and effective geographic information carrier, contemporary GIS technology with the rapid development of the Internet and the rapid updating and development, and their combination produces the WEB-GIS (network geographic Information System) fully concerned by computer and GIS areas, which also improves the obtaining geospatial information sharing, dissemination and analysis of the situation. However, with the growing demand for geospatial information, the traditional network geographic information system highlights its limitations, mainly reflecting in the different geospatial information sharing limited amount of data and geospatial information in two ways. For traditional geographic limitations of information technology, the appeared GML network effectively solves the traditional problems of geographic information systems, its main task is to promote the exchange and manipulate the data, the GML format files into SVG format file, and finally through the Web Posted to achieve data visualization. Keywords: GML; SVG; Visual

基于 GML 和 SVG 的灾情信息可视化研究 李尧 1,陈晨 2 1. 内江师范学院,四川 内江 641112 2. 电子科技大学 资源与环境学院,四川 成都 611731 摘 要:跟随 Internet 的迅速发展的步伐,当代 GIS 技术也在进行着快速的更新和发展,它们的结合产生了备受计算机领 域和 GIS 领域关注的 WEB-GIS(网络地理信息系统),改善了地理空间信息在网络上实现数据之间的获取、共享、发布 与分析状况。然而随着人们对地理空间信息的需求与日俱增,传统网络地理信息系统凸显了其局限性,主要体现在不同 地理空间信息的共享性受到限制以及地理空间信息数据量大两个方面。针对传统的地理信息的局限性,GML 技术的出现 有效的解决传统网络地理信息系统出现的问题,它主要的任务就是促进数据的交换和操作,将 GML 格式文件转换为 SVG 格式文件,最后通过 Web 发布来实现数据的可视化。 关键词:GML;SVG;可视化

引言 频发的自然灾害对人类造成大量的生命和财产损失,为了减少相应的损失并做好防灾工作,不同部门 之间的协同工作变得非常重要。在灾情信息中,灾情信息数据复杂多样,涉及的相关部门针对具体的灾情 信息会建立自己的灾情系统,然而灾情信息数据作为地理空间对象,具有很强的时空特性,相关部门获取 数据的手段复杂多样,这样形成的数据格式也很多,由于每个部门设计的 GIS 应用系统具有很强的针对 性,甚至以具体项目为中心的孤立发展状态,导致形成“信息孤岛”的局面,这样同样造成了人力、财力 - 53 http://www.ivypub.org/RSS
