WebGIS应用现状及发展趋势
Application status and developmental trend of WebGIS
【摘要】 WebGIS系统出现至今,我国在理论和应用等方面做了许多探索,但限于条件,目前仍处于试验阶段,至今尚无真正意义上的WebGIS应用实例。为了促进WebGIS的应用进程,有必要对这些年研究和探索的成果作一个总结。在大量浏览近几年登载在国内各类媒体上的有关学术论文、研究报告、学位论文以及应用实例的基础上,概括了WebGIS的主要特点,总结了WebGIS的关键问题和实现技术,并着重介绍了目前WebGIS在农业、林业、气象、水利、地震、海洋、国土资源、环境保护、铁路交通、电力、城市建设和规划等社会各个领域的应用现状,最后对WebGIS的发展趋势进行了探讨。研究结果表明,作为开放性的应用平台,WebGIS在我国的应用前景非常广阔。
【Abstract】 Since the concept of WebGIS appeared, its theory and application have been researched in our country. But it is still under the experimentation until now, so it cannot be called the real "WebGIS". So it is necessary to summarize the research results for these years. This paper sums up the main characteristics of WebGIS on the basis of collecting and studying a great deal of published scientific thesises, research reports, degree thesises and applications. The paper also sums up the key problems and realizing technology of WebGIS, and its application status in agriculture, forestry, weather, water conservancy, earthquake, ocean, land and resource, environment protection, railroad and traffic, electric power, city construction and programming are emphasized. Finally the paper discusses the development trend of WebGIS. The conclusion is that WebGIS can be used more widely as an opening application platform.
