摘　　要：提出了一种基于单机计算资源的遥感网络服务构建模型——遥感服务模拟器。将遥感网络服务抽象为用户交互、模型计算和结果反馈三个部分,通过设计基于HTTP协议的用户交互映射机制、长时通信机制和多用户并发机制,将单机遥感模型直接映射为网络服务。实验证明,该方法可充分利用已有的单机遥感计算资源,只要遥感模型具有控制台交互的特征,就可实现向网络服务的直接迁移。A new model, named computation service emulator, was proposed for fast transplanting local remote sensing programs to web services. In the model, computations of the web application are accomplished by local programs, and after that, the imeraetions under HTFP protocols including nmechanisms of the interaction mapping, the long-time connection, as well as the concurrent access, are simulated, based on which the local programs can be employed directly for web services. Experiment results show that the model can take full advantages of existing local remote sensing programs, and as long as the local programs have consoles, they can all be transplanted to web services directly without any modification.
