地理国情信息系统设计与实现

地理国情信息具有重要的经济、军事应用价值。结合空间数据库技术、地理信息服务技术及数字地球技术,设计并实现了地理国情信息系统。采用CS架构模式,利用Arc SDE存储地理国情空间数据,通过Map Service提供数据服务,基于Osg Earth实现地理国情信息加载、调度和显示。实际应用表明,该系统能够高效地对地理国情信息进行管理和表达,且具有良好的可拓展性和可移植性。

Design and Implementation of the National Geographic Information System

National geography information has important economic and military value.We designed and implemented a national geography information system,which is based on geospatial database technology,geographic information service technology and digital earth technology.By using client and service architecture,storing spatial data in ArcSDE,servicing data through Mapservice,we implemented the loading,scheduling and displaying national geography information based on OsgEarth.Practical application shows that this system can manage and display national geography information efficiently,and can be expanded and transplanted.
