Abstract

This disclosure provides a method, apparatus, electronic device, and medium for processing and managing raw remote sensing satellite data. The method includes: acquiring the bitstream of raw satellite data; defining a data segmentation mode, wherein the data segmentation method includes whether the data is segmented, the segmentation method itself, and specific segmentation parameter values ​​for each segmentation method; for segmented satellite data, performing segmentation processing on the satellite data according to the segmentation method and the specific segmentation parameter values ​​for each segmentation method to generate segmented raw remote sensing satellite data; and generating metadata information for each segmented raw remote sensing satellite data, wherein the metadata information is used for managing and querying the satellite data. Based on the remote sensing satellite raw data processing and management method provided by this disclosure, the problems of inconvenient transmission, long processing time, wasted bandwidth, and reduced timeliness of transmission of other satellite data caused by the existing single-track, single-channel, and single-data-file processing methods in managing remote sensing satellite data can be solved.
