摘要
随着遥感数据时间分辨率、空间分辨率、辐射分辨率和光谱分辨率的全面提高,遥感数据量将迅速扩大。为建设适度可用的遥感数据服务系统,实现遥感数据高效管理,提出了系统处理能力需求估算模型,并结合案例进行了处理能力需求估算,针对案例提出了系统设备配置建议。分析表明遥感数据服务系统处理能力需求估算方法切实可行,结果可对遥感数据服务系统中数据库服务器、应用服务器及存储设备的配置与选型提供支撑。
The data volume of remote sensing is now increasing dramatically as more data are generated with high temporal resolu- tion, high spatial resolution,high radiometric resolution and high spectral resolution. A new processing capacity demand evaluation model for remote-sensing system is presented, which can be used to predict the demand and requirement of equipment needed for providing ef- ficient data service at modest cost. An example is discussed to show how to work out the processing capacity demand and corresponding equipment configuration plan. Analyzing results proves that the model is feasible and practical in predicating system equipment demand and selecting commercial productt for establishing remote - sensing data service systems.
