The Services Sharing of Remote Sensing Data in Digital City
数字城市中遥感数据共享服务的研究

As important spatial information resource, the sharing of remote sensing data is essential to realize digital city. The structure of remote sensing sharing is proposed in this paper, which is composed of management tier, data tier, service tier and application tier. On the following the key technologies of service sharing platform are discussed and a prototype system has been implemented to prove the feasibility of the architecture.
