摘要
通过分析现有遥感产品生产平台的并行策略与处理流程,结合现有的数据流模型,提出了一种XML驱动的遥感产品生产并发数据流模型,并给出该模型的文法以及并发性驱动原理。该模型通过适配XML驱动文件,有很好的拓展性。通过对模型并发性的分析,认为该模型在提高遥感产品生产效率、优化并行策略和可视化信息展示上有一定的优势。
Through analyzing the parallel strategy and process of remote sensing production platform, combined with the existing data flow model, a XML-driven concurrent data flow model of remote sensing products is proposed in this paper, the grammar descriptions and concurrency drive principle of this model is shown. The model has good scalability by configuring XML files. Through the analysis of the model＇ s concurrency, it can be seen that the proposed model has certain advantages in improving the efficiency of remote sensing product production, optimizing parallel strategy and visualizing information display.
