Evaluation of CBERS-2 CCD data for agricultural monitoring

The China Brazil Earth Resources Satellite (CBERS)-2 CCD has 4 bands of 19.5m spatial resolutions in the visible/near-infrared wavelength regions and 1 pan band of 19.5m spatial resolutions. These bands (except pan) have the same spectral zones as Landsat7 ETM+ multispectral bands. In this paper, we compared the performance of CCD image with ETM image from 4 key aspects in order to accelerate its application for agriculture monitoring. These 4 key aspects are geometric correction, typical surface features identification, land target area measurement, image classification and interpretation. The results show that CCD image can be geometrically corrected with high accuracy, is better than ETM+ image for typical surface features identification, records the small land targets in detail, can be more suit for recognition by eyes, can be used for measuring land targets area with high accuracy, has the same good performance as ETM image for image classification and interpretation. CBERS-2 CCD shows great potential for the applications of agricultural monitoring
