Multi-satellite remote sensing data integrated parallel ground pretreatment system

Abstract

The invention relates to an integrated parallel ground preprocessing system for multi-satellite remote sensed data. The system comprises a hardware layer, a system supporting layer, a data processing and expanding layer, a task managing and dispatching layer and a user processing function combining layer, wherein the hardware layer provides hardware support for the preprocessing system; the system supporting layer provides a software support environment for the system; the data processing and expanding layer is provided with abstract function interfaces and public function combinational logics of various satellites and various sensors; the task managing and dispatching layer is used for realizing task dispatching and flow management; and the user processing function combining layer provides simple and practical flow combination interfaces for users. The preprocessing system has the advantages that the users can conveniently and uniformly expand processing, memory and network communication capacities of the system without modifying the processing program, thereby increasing the operating speed of the program; when new satellite remote sensed data enter the system and require processing, archiving, product production and distribution, function expansion can be completed only by adding processing modules of corresponding data into the system according to a certain template.

Description

Technical field [0001] The invention relates to the technical field of ground preprocessing of remote sensing data, in particular to a high-performance multi-satellite remote sensing data ground preprocessing system based on a parallel cluster architecture. Background technique [0002] The remote sensing satellite ground preprocessing system is a comprehensive system integrating satellite data archiving and management, data preprocessing and product generation. It is an important support system for the space earth observation system and the link between the acquisition of related space data and ground applications. With the rapid development of information technology and sensor technology, the spatial resolution, spectral resolution and time resolution of satellite remote sensing images have been greatly improved. The amount of data collected on the satellite has increased by 100-400 times, and the corresponding data processing calculation has also increased by 1000- 10,000 time...
