摘要
流域基础信息通常以书本为载体,虽然信息详尽,但无法满足用户对信息快速查询的需求。因此,为了适应信息快速获取的实际需求,开发了基于OpenLayers开源JS库的WebGIS数据库系统。探讨了流域基础信息的主要内容与重要性,设计了流域基础信息数据库与系统结构,实现了WebGIS客户端通过对地图的精确定位查询流域基础信息与信息的可视化等功能。重点介绍了OpenLayers的特性、OpenLayers的数据处理原理以及流域基础信息数据库的设计。以中国新疆塔里木河流域基础信息为测试数据,测试结果表明,通过在地图上多方式查询流域基础信息不仅能满足专业与非专业人士对流域基础信息的获取,而且能直观高效地展示空间信息,是一种实用的流域信息获取方式,基于开源平台的系统设计也降低了开发复杂度和成本。
The basic information of river basin is usually based on books.Although the information is detailed,it cannot meet the needs of users for rapid information inquiry.Therefore,in order to meet the actual needs of rapid information acquisition,we develop a Web GIS application system based on OpenLayers open source JS library.We discuss the main contents and importance of river basin basic information and design the basic information database of river basin and the system structure,to achieve the Web GIS client through the precise positioning of the map query and information visualization of geographic information and other functions.It focuses on the characteristics of OpenLayers,the data processing principle of OpenLayers and the design of basic information database of river basin.With the basic information of Tarim River Basin in Xinjiang as test data,the test shows that on the map in a multiple ways to query basic information can＇t only meet the professional and nonprofessional persons to obtain basin basic information,but also can display spatial information intuitively and efficiently.It is a kind of practical way basin on information acquisition,and the system design based on open source platform also reduces the complexity and cost of development.
