| 摘 要： | 随着当前异构空间信息源的快速增多,GIS系统中如何有效地集成和整合应用多源空间数据成为GIS研究的关键点和难点之一。本文首先分析和研究了当前几种常见多源空间数据的集成方法,借鉴并吸收这些方法的优点,同时结合空间数据应用的实用性,提出了通过基于ArcSDE和Socket通信机制的混合中间件来实现实时多源空间数据的统一管理,利用ArcGIS Server提供非实时空间数据服务的解决方案,并对二者进行有机的整合。基于本文所提出的多源空间数据混合集成机制,构建了MODIS水利应用与发布平台并实现了高效的应用,该平台的应用实践有力地证明了该集成方法的灵活性和高效性。最后,针对集成方法的进一步完善提出了一些建议。

| Abstract: | With the rapid growth of heterogeneous spatial information resources,how to integrate and manage multisource spatial data efficiently in GIS system has become one of the key points and difficulties in GIS.Firstly,several main multisource spatial data integration methods were analyzed and studied in the paper.Drawing on their advantages and combining with the real-time feature in spatial data application,it proposed a new solution that managed real-time spatial data with hybrid-middleware,which mixes with both ArcSDE and Socket communication mechanisms,provided non-real-time spatial data service with ArcGIS Server,finally integrated these two organically.Based on the mixed spatial data integration mechanism,a platform for water application and publishing of MODIS data has been set up,and applied in high performance,which proved the mechanism for spatial data integration proposed in this paper was flexible and efficient.At last,some advices for further improvement on this approach were given. |
