【摘要】 WebGIS是近来GIS领域的一个应用研究热点,其中多数据源的有机集成是制约其推广应用的关键问题。以路政信息综合查询为研究背景,在ArcIMS的基础上,通过引入ArcSDE和WebService技术,有效解决了WebGIS环境下的属性数据、空间数据、以及各种多媒体数据的有机集成问题,进而在数据层面上实现了与其它相关系统的数据整合,并在此基础上实现了基于Web的路政信息综合查询系统。更多还原

【Abstract】 WebGIS is an application study hotspot of GIS field recently.The organic integration of multi-data sources is the key problem which restricts its popularization and application.Regarding road information integrated query as the background of studying,the organic integrated problems of attribute data,spatial data and different kinds of multimedia data under WebGIS are solved based on ArcIMS effectively through introducing ArcSDE and web service technology,and then the data integration with other related systems is imple-mented,and thus the road information integrated query system based on web is realized.更多还原
