Remotely sensed image distributed processing system design with web services technology

With the development of Remote Sensing and digital image processing technology, it become's very important and imminent for remotely sensed images to be processed in the distributed environment. This paper aims at the implementation of remotely sensed image distributed processing, firstly analyzes the current implementation method and technique of remotely sensed image distributed processing, then points out the problems it faces. After analyzing the characteristics of web service technology, this paper draws the conclusion that web service technology can be applied to remotely sensed image distributed processing field because it can solve these problems, such as large amount of data processing and network computing and so on. This paper firstly gives the framework design of remotely sensed image distributed processing based on web service, then takes remotely sensed image distributed edge detection and segmentation as the example, according to the need of our image distributed processing task, this paper gives the interfaces and classes definition. then talks about their implementation method. At last we give in example and its image processing effect of our distributed system, and the result shows the feasibility of the remotely sensed image distributed processing implementation with die technology of web service.
