Aimed at promoting the application of data obtained by China-made satellites, this paper deals with the gradual deepening of the “principal user” application mechanism of the 02B satellite by means of setting up the relevant organization, making practicable working arrangement and popularizing the application of CBERS—02B satellite data.

In the light of the application of land and resources and on the basis of the “indicator-simulation-assessment-revised targets-simulation-assessment” model, the authors established an assessment system composed of four components, i.e., software system, hardware system, technical standard and technical method. A relatively perfect assessment and evaluation system based on the application evaluation of land and resources was also built. This research provides new thoughts and new technical system support for the development and data application of satellites in China.

More and more modern high resolution optical remote sensing satellites are being equipped with TDI CCD cameras. Modulation Transfer Function (MTF) is an authoritative means in evaluating the quality and implementation capability of the imaging system. For the purpose of evaluating the satellite criteria in the phase of production, it is necessary to simulate images with the satellite MTF criteria in enough reality. Based on a detailed analysis of the relationship between the satellite criteria and the on-orbit satellite TDI CCD imaging degeneration, this paper gives a method for the simulation of the degeneration process. With the method, a soft ware system was built to simulate the on-orbit imaging process of the designed satellite, which can provide the application experts with a powerful tool to judge the satellite in designing and production.

From the change of a satellite images consumer to a holder of satellites, we are facing the challenge of evaluating the satellite and its payload technical criteria rather than images from satellite image vendors. With over tens of years of special application, the application experts have gained lots of experience to evaluate images instead of the criteria of a satellite. It is therefore necessary to bridge the gap between the satellite producing experts and the application experts, with the simulation of satellite imaging. The goal of the simulation is to connect the satellite and its payload technical criteria with the radiometric and geometric qualities of its images, and this technology will play a key role in the application assessment and the development of the application system in the phase of manufacturing the satellite. As the physical process of the imaging of an on-orbit satellite is very complicated, and perfect simulation of its imaging is a great challenge in both technology and engineering, the authors’ simulation technical framework focuses on the simulation of degeneration of the radiometric and geometric qualities of the images which constitute the fundamental criteria in land and resources management application. In this paper the authors have given a detailed description of the framework for digital simulation of the high resolution optical sensor and verified it with China-made 02B satellite equipped with a high resolution optical sensor of 2.4m ground sample resolution. A potentially improved simulation framework is also put forward.

To establish the application evaluation system of land and resources, the authors have dealt with the main satellite remote sensing evaluation factors in the field of land resources and geological resources application.

The evaluation was performed according to the technical standard of land surveying and monitoring in association with the quality of image data, band registration and geometric distortion and was based on the routine of land and resources surveying, administrative regulations and law enforcement. In addition, the capability of applying CBERS 02B CCD and HR image data to the surveying and monitoring of land and resources is summed up, and the existent problems are analyzed preliminarily in this paper, which seems important for the application of CBERS 02B image data and the development of satellites in future.

Based on characteristics of the CBERS image and the theory of the atmospheric radioactive transfer model and using MODTRAN as the core of the algorithm, the authors established the aerosol optical depth search table to correct the atmospheric influence. This means can meet the needs of operational quantitative products of CBERS, and can also yield fairly good application effects, as was evidenced by using the CBERS image in the atmospheric correction along the Gailingjiang River valley of Guangyuan in Sichuan Province on August14, 2005.

In order to study the feasibility of CCD multispectral data of CBERS and expand the geographic information of RS image sources, this paper, exemplified by CCD multispectral data of the CBERS image, carried out some experiments on two kinds of rectification models and the influence of three different kinds of correction control materials on precision appraisal. On the basis of these experiments, the author developed a time-saving and energy-saving method for CCD multispectral data of the CBERS 1∶100 000 image.

The data sources from the CBERS—02B satellite in the panchromatic band, multi-spectral band and IKONOS multi-spectra were used to perform the fusion test by DWT and DTCWT. The results show that the DTCWT could achieve a fairly good balance between the details of the space and the maintaining of the spectra, thus improving the quality of image fusion. In comparison with other fusion methods, the CBERS—02B panchromatic band can not only yield images of more information with the fusion of its multi-spectral band but also result in a good visual effect and readability with the fusion of other sensor data. The CBERS—02B satellite therefore has remarkable application prospects.

This paper describes characteristics of the ZY-02B pan image and its producing process, and then puts forward a simplified method for the replacement of its imaging model. Aimed at solving the problem of inner distortion caused by the installment means of CCD, the authors advanced a computation method for positioning elements through introducing inner elements. The positioning precision was examined by using different ranks of OE ratio, and then the adjustment was made by using some control points, which eliminated most systematic errors and attained a fairly good precision.

CBERS—02B multi-spectral CCD data are considerably different from HR panchromatic data in resolution, which causes great difficulty in image fusion. Based on an analysis of such means as the IHS transform fusion method, the principal component transform fusion method, the Brovey transform fusion method and the GS transform integration algorithm, the authors tested the fusion methods on CBERS—02B data. The evaluation of the visual and quantitative analysis of the results reveals that the PC and GS transform fusion image texture information is fairly clear and has better spectral fidelity. In the GS transformation fusion, Band 5 of the CBERS—02B CCD camera can be used as the low-resolution analog input, and the result of the statistical value is better than that of the PC transform.

The acquisition of high-spectrum and high-resolution satellite data has experienced a period of more than ten years, with abundant data of high resolution satellite images stored in the archives. Such kinds of information as small faults, bonanzas and stocks (dykes) can be interpreted by these high resolution remote sensing data, which seem to be closely related to numerous metal deposits in normal cases. This method can therefore serve as a means in search for metallic deposits.
