A Service Pipelining Model for Web GIS Based on Distributed Environment

Pipeline is one of the classic technologies to enhance efficiency. When the amount of data is becoming more and more big when processing, it becomes a big problem that how to improve the efficiency with existing resources. In the meantime, a large number of older hardware and software feel difficult to deal with new task in new environment with the accumulation of time. In order to ameliorate efficiency of web GIS with low cost, this paper propose a service pipelining model for Web GIS based on distributed environment. The system build a basic service library to reuse plenty of existing resource, and design a segment system to organize pipeline in level of service to improve efficiency. The model can be used in many platforms and occasions, not limited to the application we proposed in this paper. The model we proposed has been proved work well in our experiments and test.
