It’s urgent to consider how to systematically establish the civil aeronautics remote sensing system

assimilate application requirements in the process of remote sensing quantification

and improve the earth observing ability and quantitative level.On October 21

2003

the CBERS-02 was successfully launched.Charge Coupled Device Camera（CCD）

Wide Field Imager（WFI） and the Infrared Multi-Spectral Scanner（IRMSS） are three important payloads on CBERS-02.The quantitative researches and experiments based on CBERS-02 data had been carried out

which provide a reference and demonstration for the quantitative application researches of FY

HY

Resources

HJ etc.satellites data.To conducted the quantitative application of the CBERS-02 satellite images

we have performed a series of experiments and researches.Researches on the quantification application of CBERS-02 include good knowledge of the payload’s parameters

image’s quanlity

radiometric calibration

validation of arithmetic models and the assessment of the application potential.As one of these research

the method of radiometric calibration and coefficients of the CCD

WFI and IRMSS have been published

which has provided basic support to the quantitative application of the CBERS-02 satellite images.In this study

the remote sensed data processing frame and products system are designed based on the characteristic of the CBERS-02 images.The study demonstrates that the functions of quantifying processing for CBERS-02 satellite include the stage from the remte sensed signals to quantitative information and to the inversion of the surface parameters for CBERS-02.To provide a compositive product system for CBERS-02 satellite

five level products have been designed based on the consideration of geometric and radiometric characteristic of CBERS-02 satellite

which will be a reference of the product system for the coming high spatial resolution satellite image in our country.The five level products are: Level 1（1B data）

Level 2（relatively radiometric calibration product

MTF compensated product

coarse geometric registration product

accurate geometric registration product）

Level 3（appearance radiance

appearance reflectance

appearance brightness

cloud identified product）

Level 4（surface reflectance

surface brightness

surface albedo

LST） and Level 5（vegetation index

LAI

land cover

FPAR）.In this study

techniques of quantifying processing for every level product are illustrated completely for CBERS-02 satellite.For the stage from the remote sensed signals to quantitative information

the vicarious calibration and cross-calibration of CCD

WFI and IRMSS images

cloud detection arithmetic of CCD images and atmospheric correction method of CCD images.For the absolute radiometric calibration for the CBERS-02 satellite

vicarious and cross-calibration are performed and the calibration coefficients are achieved for CCD camera and IRMSS camera.And the cross-calibration is also carried out for WFI imager and the calibration coefficients are calculated as the first time in China.For the stage from quantitative information to the inversion of the surface parameters

the following products will be processed and achieved: surface reflectance

surface albedo

vegetation index

LAI

FPAR

land cover and LST

ect.Based on these quantitative researches

the professional quantifying processing software for CBERS-02 satellite

Remote Sensing Quantitative application software:CBERS（RSQA-CBERS） is developed

which will facilitate the quantitative application of the CBERS-02 satellite.The development environment of RSQA-CBERS is MS-Visual C++.However

the current version of RSQA-CBERS is running based on the Level 2 product which is defined and provided by the center of Chinese Resource Satellite data and Application（CRESDA）.Thus

due to the limitation of the images

the surface parameters inversed by the software are limited.What’s more

the inversion arithmetic need to be improved.
