一种基于Web前端的在线空间数据管理技术方法 A Technical Method of Online Spatial Attribute Data Management Based on Web Font End

本文通过基于B/S架构的WebGIS系统，实现空间数据的web前端可视化管理，通过HTML5、CSS3实现浏览器端数据管理UI界面，通过Javascript实现浏览器端和用户的交互功能。服务器端使用SQLite数据库存储数据，数据库的设计采用数据存储表和数据字段映射表实现数据字段的动态管理。本实验室自主研发的Geoserver2013平台充当web服务器进行web应用的发布，通过该平台提供的一系列数据库管理API，AJAX技术实现数据的前后端交互，从而实现数据的前端管理和后台存储功能。通过管理数据库表中的资源表和资源控制表，实现地理空间属性数据的共享。 Based on B/S framework of web system, this article realizes the visualization management of web front end of spatial data. According to HTML5 CSS3, the User Interface of data management in web browser is realized, and Javascript can be used to achieve the interaction between web browser and users. The server uses SQLite database to store data, the design of the database with data storage table and data field mapping to realize dynamic management. The Geoserver platform of in-dependent research is used as a web server for web applications; this platform provides a series of database management API, including WebSQL API and SQLScript API, and transforms the data between server side and browser side with AJAX, so as to realize the data of the browser side management and server side storage. By managing the resource table and resource control table in the database, the sharing of spatial attribute data can be realized.
