摘要
提出了利用网格技术实现分布式海量空间信息搜索的方法,基于网格开发工具ProActive开发了海量空间信息网格调度服务。利用鼠标屏幕取词、中文地名识别和基于网格的海量空间信息搜索技术,设计并实现了一个海量空间信息隐形搜索引擎,实现了即时、隐性、动态获取中国300个城市的空间信息。为海量空间信息服务提供了一种全新的技术。
This paper presents a method of massive and distributed spatial information search based on grid technology. The service of grid dispatch for massive and distributed spatial information is developed by using gird development tool ProAetive, A massive spatial information hidden-search engine is designed and implemented based on the integration of capturing words from screen technology, identification technology for geographic position name and massive spatial information search on grid. The service of instantaneous, implicit and dynamic spatial information acquiring for 300 Chinese cities is also achieved. The engine provides a new technology for massive spatial information services.
