江苏省CBERS-1卫星红外数据应用示范研究评价

文章对CBERS -1卫星IRMSS数据从空间分辨率、几何精度、噪声等方面作了分析评价 ,选取典型的南京地区、洪泽湖作为示范应用区 ,经过几何精纠正后的IRMSS数据进行不同地物在不同波段上的光谱采样分析 ,进行了城市信息与湖泊信息提取实验 ,效果较好 ,对南京辖区和洪泽湖的形态特征、环境因素、动态变迁等方面作了分析研究 ,从图像上可以清晰地看出南京辖区水体、城建和交通以及郊区的农林状况、洪泽湖河口淤积、岸边污染的情况。总之 ,CBERS-1卫星IRMSS数据可用 ,质量较好 ,达到了设计要求 ,有广阔的应用前景。

Research and Evaluation of Applying Infrared Data of CBERS- 1 Satellite in Jiangsu Province

The paper analyses the IRMSS data based on spatial resolution, geometric accuracy, noise and so on, and selects Nanjing area and Hongze Lake as the demonstration area. In term of the different geographical objects at the special bands, the IRMSS data, which had been geometric, rectified were sampled and analyzed. After picking up the information of city and lake, the results were proved to be quite efficient. Meanwhile, this paper also discusses the configurable characteristic, the environment factor, and the dynamic movement in the Nanjing area and Hongze Lake. It was found out that water body in Nanjing area, urban construction and transports of Nanjing area, the alluvium at the entrance of Hongze Lake and so on can be clearly identified from IRMSS images. As the results, the paper brings out that IRMSS data of CBERS-1 satellite have good quality and attains up the designing requirements; they can be widely applied in many fields.
