Abstract

The invention discloses a remote sensing data management method based on a fragmentation mode, and the method comprises the steps: carrying out the unified data matching preprocessing of a remote sensing image and metadata, segmenting a data block before storage on the basis of a remote sensing data segmentation model, and storing the data block in a database in a high-efficiency manner. uploading data to a data center in a network transmission mode, distributing massive data blocks to different data nodes through unified allocation processing of the data center, and in the data nodes, issuing the data reasonably to each fragment in order to guarantee a load balancing routing process, so that a user can access the data. According to the distributed data structure of the remote sensing data, retrieval, integration and sharing of the remote sensing data are achieved, query of a plurality of requests is combined into one time under the high concurrency condition, the number of access times of a database is reduced, a new distributed management thought is provided for integration of the multi-source remote sensing data, and a theoretical and data structure basis is provided for parallel calculation.

Description

Technical field [0001] The present invention belongs to the field of remote sensing data management, and in particular, the present invention relates to a remote sensing data management method based on fragmentation mode. Background technique [0002] The change in the atmosphere, ocean, land and vegetation in the earth system is realistic, affecting human being obtained, the earth as a comprehensive system, including all areas involved in the disciplines and information technology. The observation of the earth system provides useful information source provided by human understanding of the earth system, and has also become an irreplaceable research pathway for human research. Only the local observation system can provide global multi-phase continuous earth data, which can be used to use the earth system as a whole description, and the ground observation system includes a local observation satellite, an airborne remote sensing system, a ground observation data receiving system Wa...
