基于Google Map API的国界信息发布系统研究

Research of borders information distribution system based on Google Map API

边界工作是我国外交工作中一项长期而重要的任务,如何实现周边事务的快速标绘、实时共享和制图输出,对于政府决策者以及外交工作人员具有重要意义。然而目前的国界信息系统大多存在地理空间数据更新工作繁重、缺乏实时标注工具和地理事件难以共享等问题,已严重制约了边界工作的顺利开展。地理信息技术的进步与发展为解决上述问题提供了可能。文中采用四层B/S体系结构,在Google地图服务支持下,基于ASP.NET+C#网页开发技术和Ajax技术设计并实现了国界信息发布系统。为政府决策者及外交工作人员实时标注和共享周边信息提供辅助决策支持。实践证明,系统具有良好的可用性和较强的实时性。

Border work is a long-term and important task in China's diplomatic work.How to implement rapid plotting,real-time sharing and mapping surrounding affairs has taken great significance for government policy-makers and diplomatic staff.However,the existing boundary information systems have some problems:of which geospatial data update is heavily workload,plotting tools are in a state of serious lack and geographic events are difficult to share,which phenomenon has seriously hampered the smooth development of the border task.The development of GIS technology,especially the development of Web GIS offers the possibility to solve the above problems.Four layers of B/S architecture are adopted with the support of Google maps service,design and implement the borders information distribution system based on the web development technology of ASP.NET,C#,Ajax.The system can provide a decision support for the government policy-makers as well as diplomatic staff's real-time plotting and sharing of surrounding information.The practice has proved that the system has good usability and strong real-time.
