Research on technology of the global geographic data sets generation based on the original remote sensing data

To meet the simulation and testing requirements of HY-1 Satellite ground operation control system simulation subsystem, a global geographic data sets based on original remote sensing data was proposed. This paper detailed the function and data processing methods of the data sets, mainly including data structure and the key algorithm of the satellite calibration and data filling required in the data sets generation process. At last, using the data simulation function of ground station, the generated raw data would be sent to real ground operation control system, and the processed images showing the data sets were filled with good results.
