Abstract

Abstract: 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.
