Based on international requirements for the application of commercial remote sensing data,an information service system for receiving and processing multi source remote sensing data was developed and introduced.The system consists of an Oversea Fixed Ground Service Station(OFGS),a Transportable Vessel-Borne Service Station(TVBS) and a Data Operation and Management Center(DOMC).Fixed and transportable service stations were developed in Venezuela,Latin America and for the China's Xuelong polar research vessel respectively,and serve the function of remote sensing data receiving,processing and application.The DOMC connects the OFGS and TVBS,so that they constitute a network to provide receiving,distribution,retrieval,browsing,ordering,and downloading functions for multi remote sensing satellite data and products.It validates the competence in providing 40 kinds of typical application products.The development of this system provides a reliable and comprehensive service for commercial remote sensing data applications for users both in domestic and oversea markets. 展开更多
