摘要
随着地理计算问题的日益复杂和计算规模的不断扩大,目前很难通过手工对复杂地理计算过程进行控制。提出了一种基于科学工作流技术的地理计算流程管理方法,设计了地理计算流程管理系统的结构和功能,引入开源工具Swift进行系统实现,验证了科学工作流技术用于管理地理计算流程的可行性。最后,通过住址选址案例表明该系统能够通过提高计算任务的并行程度来加速地理计算。
With the more complex geocomputation problem and the larger computation scale,it is currently difficult to control complex geocomputation process manually.A geocomputation process management method based on the scientific workflow technology is proposed,and the architecture and functions of the geocomputation process management system is designed.An open source tool named Swift is used to implement the system,and the feasibility of the scientific workflow technology applied to manage the geocomputation process is verified.Finally,a residential site selection case shows that the system can accelerate geocomputation by improving the parallel execution extent of the computing tasks.
