EVALUATION OF CBERS-1 DATA QUALITY AND ITS APPLICATION TO SUSTAINABLE DEVELOPMENT IN JIANGNING

摘要

It is important to evaluate data quality of the China-Brazil Earth Resource Satellite (CBERS-1) data with the application of the data to various fields effectively. In this paper, the major technical performance index of CBERS-1 is given and compares with the SPOT data. And the data received by high resolving power CCD camera (19.5m) is selected. The study data include three wave bands which are the second, third, fourth wave band. The topical study area is chosen from the Jiangning of CBERS-1 CCD data, the size is 1180 multiply 1180 pixels. First the CBERS-1 data is removed of stripes and processed by geometric correction. And the data quality is evaluated. Then the image is integrated with the SPIN-2 (2m) image by IHS transformation. And the merged images are analyzed. From that, it is to be sure that the CBERS-1 data could be used to updating of topographic map database on the scale of 1:100,000 or 1:250,000□mapping of land use from multi-spectral classification□growing monitoring of crops and analysis of agriculture structure adjustment□etc. The CBERS-1 data will have wide application prospect in the sustainable development project of Jiangning.
