Abstract:

Hyperspectral image has a large amount of data and complex structure. The distributed storage of massive remote sensing data is a hot topic today; however, the current research mostly separates the image pixels and metadata, resulting in poor system cohesion and poor data access performance. At the same time, the needs of various upper-level remote sensing algorithms are not fully considered, which makes the system less available. In view of the above problems, this paper presents a distributed image storage model based on HDFS, which stores the entire image data model in a structure to improve the system cohesion, and provides a flexible data blocking strategy for upper-level applications to meet a variety of data access needs. The comparison experiments show that the storage model has better access performance than the existing schemes.
