LANDSAT-5 TM Data Radiometric Correction and Geospatial Positioning Accuracy[J]. Journal of Image and Graphics, 2008, 13(6): 1094-1100. DOI: 10.11834/jig.20080611.
which are two key steps for quantitative remote sensing information
are crucial to reveal the target and background character and the actual geographical position. In this paper
a method of radiometric correction and the geospatial positioning accuracy of Landsat 5 TM data processed with precise ephemeris parameters is introduced. Test with the Landsat 5 TM data verified that the method used in China Remote Sensing Satellite Ground Station is effective to eliminate the system errors produced during the imaging process.
