摘要
为了满足用户实时访问和使用需求,数据更新是确保地理信息服务平台长期有效运行的一个不可或缺的因素。针对空间数据、全景与街景数据提出了变化信息发现方法和数据更新方法,采用几何匹配和影像对比发现变化信息,通过整体、局部、点线面等方式进行数据更新,确保数据更新实时、准确、高效,保证地理信息服务平台内容的时效性。
In order to meet users’real-time access and use needs,data update is an indispensable factor to ensure the long-term effective opera-tion of geographical information service platform.In this paper,we put forward the change information discovery method and data update meth-od for spatial data,panoramic and street view data.We found the change information by geometric matching and image comparison,and updated the data through overall updating,local updating,point,line and surface updating,so as to ensure the real-time,accurate and efficient update of data,and the timeliness of geographical information service platform content.
