Problems solved by technology

[0002] Most of the existing remote sensing data storage systems based on distributed file systems are simple patchwork of existing systems, lacking the support of mainstream big data processing frameworks, which brings a lot of inconvenience to the processing of remote sensing data
At the same time, because the remote sensing data itself contains many types of data, the existing distributed file system cannot directly store various types of remote sensing data, and lacks a unified interface to manage various types of data, which brings inconvenience to users. Major inconvenience

Abstract

The invention provides a method and a system for storing remote sensing data on the basis of distributed file systems. Distributed storage frames for remote sensing application are created by the aid of the method, the remote sensing original image data, metadata and slicing data are stored, two access interfaces are defined and include a MongoDB access interface and an HDFS/Hbase direct access interface, and the method and the system are compatible with existing remote sensing data processing platforms. The method and the system have the advantages that different types of remote sensing data can be stored in a distributed manner according to the method, and the remote sensing data can be accessed and processed by the aid of the provided access interfaces.

Description

technical field [0001] The invention relates to the technical field of remote sensing image storage, in particular to a remote sensing data storage method and system based on a distributed file system. Background technique [0002] Most of the existing remote sensing data storage systems based on distributed file systems are simple patchwork of existing systems, lacking the support of mainstream big data processing frameworks, which brings a lot of inconvenience to the processing of remote sensing data. At the same time, because the remote sensing data itself contains many types of data, the existing distributed file system cannot directly store various types of remote sensing data, and lacks a unified interface to manage various types of data, which brings inconvenience to users. Major inconvenience. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a remote sensing data storage method and system based on a distribut...
