Relative radiometric calibration is a very important way in improving the quality of picture getting from remote sensing satellite,and calibration by radiometric calibration sites is just an effective method in relative radiometric calibration.

Topographic correction based on sun-canopy-sensor(SCS) geometry is more appropriate than terrain-based corrections in forest areas because SCS preserves the geotropic nature of trees(vertical growth) regardless of terrain,view,and illumination angles.

Topographic correction is one of the major tasks for remote sensing imagery correction.

Estimation models of vegetation fractional coverage (VFC) based on remote sensing image at different radiometric correction levels.;

Estimating living vegetation volume from a multiple radiometric correction SPOT 5 Imagery

The relative radiometric correction is the first step of processing and analyzing of multitemporal remote sensing images.

On the basis of deeply studying on CCD remote sensing image radiation correction technology of CBERS-2 satellite,the technology of level 0 image pre-processing,sensor calibration,atmosphere radiation correction,solar irradiation correction are presented.

The automatic detection and radiation correction of a highlighted face area is helpful to analyze and identify human faces correctly in a color image.

TM remote sensing data of September 18,2007 and July 18,2008 were collected in the view of radiation correction theory by first doing remote sensing images radiation correction which can changes DN value to the apparent reflectance,then using NDVI processing to do density partition and classification,and finally getting the vegetation cover information.
