摘要
Based on web services and the Activiti 5.0 workflow engine,we built a workflow-based web service chain processing flow platform to simplify the operations of complex geospatial information processing applications in the area of high performance geocomputation.The proposed framework includes a web portal and a convenient mode for similar specific applications.We also designed a general service publishing template for high performance commutating(HPC)that can reduce platform differences among different HPC systems and facilitate HPC techniques to improve processing efficiency.Finally,we used a digital elevation model to verify and test the platform.The results indicated that the proposed service chain platform offered convenience and efficiency when processing massive data with HPC.
