摘　　要：当前尚无主流的遥感信息模型(RSIM)高性能处理平台,RSIM的研究与应用以项目驱动为主,处理低效。分析当前遥感领域数据与处理的特点,提出一种集数据存储、模型计算、信息发布于一体的RSIM处理平台。通过对存储系统、并行处理环境和调度系统的设计实现平台的海量存储、灵活管理和模型自动快速计算功能。实验表明,该系统能完成RSIM的快速高效处理,具有良好的可控性和适用性。There is no mainstream high performance processing platform for remote sensing information models ( RSIM) by now. Theresearches and applications of RSIM still remain to be driven by individual projects with low processing efficiency. By analysing thecharacteristics of data and processing of current remote sensing field, we proposed an RSIM processing platform which integrates the datastorage, model computation and information release in one step. The platform is realised the massive storage capacity, flexible management,automatic and quick computing function of RSIM through designing the storage system, the parallel processing environment and the schedulingsystem. Experiments show that the platform can achieve fast and efficient processing of RSIM, and has good controllability and applicability.
