基于Web2.0的GIS模型共享平台研究

The research of GIS model sharing platform based on Web 2.0

本文提出了基于Web 2.0建立GIS模型共享平台的设想,以期建立一个能够让用户创造模型和组织数据的GIS模型共享平台,并基于模型共享平台建立原型系统。借鉴了Web 2.0的数据自组织形式,按标签分类的方式让用户参与元数据组织,以适应各个领域用户的需求。同时为改变以往被动等待用户查询信息的方式,原型系统按RSS标准主动发布有价值信息,用户可以在第一时间获知系统更新。原型系统功能用网络服务封装,并提供客户端程序,提高了系统适用范围。原型系统的建立,证实了构建基于Web 2.0的GIS模型共享平台的价值和可行性。

This paper gives out a GIS model sharing platform based on web 2.0 application mode trying to build a platform that can help users to create model, organize data by themselves, and build an archetype system based on the platform. With the characteristic of Web 2. 0, such as data self-organizaton and tag classification, user can categorize data by themselves to fit their needs in this system. In order to improve user＇s query mode, the system release the important and valuable information using RSS standard. By web service envelop and client program, the system function has been improved greatly. The value and feasibility of the system has been tested.
