Problems solved by technology
Centralized storage mainly includes SAN storage, NAS storage, etc. In this structure of storage, the computing server and storage server are separated. The storage server is an independent device, but all file reading and writing need to go through an entrance (that is, the controller) , affected by the controller, the expansion capability of centralized storage is also limited, which makes the storage performance poor when using the above two storage methods to store massive remote sensing data

The invention relates to a remote sensing data distributed storage method, a device and a remote sensing data reading method. The storage method comprises the steps: obtaining to-be-stored remote sensing image data, and segmenting the remote sensing image data into more than one storage block; and correspondingly storing each storage block into a cluster type storage unit, creating an index file, and caching each storage block into a distributed cache layer. The index file is created to correspondingly cache the storage blocks obtained by segmentation into the distributed cache layer, so that when massive remote sensing data is stored, the overall storage performance of the remote sensing image data is effectively improved by adopting the combination of distributed cache and distributed object storage technologies. Moreover, the storage blocks obtained by segmentation are correspondingly cached into the distributed cache layer by creating the index file, and the stored data are preferentially read from the distributed cache layer when read, so that the data access efficiency is effectively improved, and the data access delay is reduced.
Description
technical field [0001] The present application relates to the technical field of remote sensing data processing, in particular to a method and device for distributed storage of remote sensing data and a method for reading remote sensing data. Background technique [0002] In recent years, my country's satellite industry has developed vigorously. With the successful launch of high-resolution and resource satellites, the amount of earth observation data received has grown exponentially. The effective storage and standardized management of massive remote sensing data has become one of the major challenges currently facing. Traditional storage methods mainly include direct-attached storage and centralized storage. Among them, direct-attached storage is simply a direct connection between computing servers and storage servers, with limited expansion capacity. Centralized storage mainly includes SAN storage, NAS storage, etc. In this structure of storage, the computing server and ...
