摘要/Abstract

摘要： 为满足多用户对分布空间数据进行远程查询、远程获取、远程协同编辑修改和分析的需求，研究开发了分布式空间数据协同编辑平台。该平台的协同机制重点解决分布用户同时编辑空间数据的冲突问题、用户数据操作的协同与群体感知问题、不同平台之间数据/消息传输的异构性等问题。为有效地解决协同等问题，提出了基于多智能体的分布式空间数据协同编辑平台的体系结构；给出了分布式空间数据协同编辑平台的通信机制和并发控制机制的设计与实现，设计了传输层的通信接口和表示层的通信接口。开发了分布式空间数据协同编辑平台系统原型，该系统可支持基于地理信息系统的规划设计应用系统。

Abstract: In order to satisfy the requirements of remote acquisition,remote query and collaborative remote editing,modification & analysis for multi-user on distributed spatial data,a Collaborative Geographical Information System (CoGIS) was developed. CoGIS has provided solutions to important problems including: conflicts of simultaneous editing spatial data among distributed users,collaboration and group perception of data manipulation among users,and heterogeneous problem of data or messages transfer across different platforms. To effectively deal with collaboration,a systematic structure of CoGIS based on multi-Agent was brought forward. Design and realization of communication mechanism and concurrency control mechanism of CoGIS were provided,and the communication interfaces of delivery layer and representation layer were designed. A prototype of CoGIS was developed and was used in planning and design application system.
