Problems solved by technology

[0002] With the continuous launch of high-resolution remote sensing satellites, people have obtained more abundant spatial information while generating massive remote sensing data at all levels. In the process of data processing, the traditional stand-alone processing platform is no longer competent. The requirements for high-resolution remote sensing satellite data processing have resulted in massive remote sensing data not being processed in a timely manner, delaying the application of remote sensing data and causing huge losses

Embodiment Construction

[0016] Such as figure 1 As shown, the remote sensing data processing system of the present invention includes a main control computer, a plurality of computing nodes and a disk array, the main control computer includes a data selection module, a data preprocessing module and a data management module, and the data selection module is used for producing The type of remote sensing product, and the required remote sensing raw data is retrieved from the disk array. The data preprocessing module divides the original remote sensing image data into small pieces of 1000*1000, and the data management module performs unified storage and management of the original data and the sliced ​​data. Name the image. And all the slices cut from an original image are placed in the same folder of the disk array, and the naming method of the folder is: satellite\sensor\year\month\day\orbit number\slice level. The data management module can preview the data of the disk array 3, view its detailed info...

Abstract

The invention discloses a remote sensing data processing system which comprises a master controller, a plurality of computing nodes and disk arrays wherein the disk arrays are used for storing the original remote sensing data and remote sensing products; the master controller is used for calling the required original remote sensing data according to the types of the produced remote sensing products, pre-processing the original remote sensing data and distributing the pre-processed remote sensing data and the original remote sensing data to a plurality of computing nodes; and the computing nodes are used for producing the remote sensing products from the pre-processed remote sensing data. The processing system for the remote sensing data can quickly process massive remote sensing data at all levels in real time, thereby ensuring the processing efficiency of the remote sensing data and producing various remote sensing products as required.

Description

technical field [0001] The invention relates to the field of remote sensing communication, in particular to a remote sensing data processing system. Background technique [0002] With the continuous launch of high-resolution remote sensing satellites, people have obtained more abundant spatial information while generating massive remote sensing data at all levels. In the process of data processing, the traditional stand-alone processing platform is no longer competent. The requirements for high-resolution remote sensing satellite data processing have resulted in massive remote sensing data not being processed in time, delaying the application of remote sensing data and causing huge losses. Contents of the invention [0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a processing system capable of processing remote sensing data in real time. [0004] In order to achieve the above object, the remote sensing data pro...
