| Abstract: | ASTER consists of three different subsystems：the Visible and Near-infrared（VNIR）has three bands with a spatial resolution of 15 m,and an additional backward telescope for stereo;the Shortwave Infrared（SWIR）has 6 bands with a spatial resolution of 30 m;and the Thermal Infrared（TIR）has 5 bands with a spatial resolution of 90 m.ASTER image can be applied in many domains such as land,sea,glacier,atmosphere and so on.This paper analyzed the structure of ASTER data in-depth,gave the method of reading the satellite position,velocity,time,attitude angle and attitude rate,then researched on the changing rule of those data.The method of radiometric correction and geo-location were presented to take the full advantage of the ASTER Image. |
