SPOT卫星资料在水深信息中的应用研究

根据卫星遥感资料的特点，结合河流、湖泊、水库等不同地表水体作的光谱测量分布成果，对ＳＰＯＴ卫星多波段图像资料提供的安徽省安庆地区的武昌湖水下地形和水深信息，利用ＥＲＤＡＳＩＭＡＧＩＮＥ图像分析处理软件、获取该湖的水下地形分布图，并与准同步实测的水下地形的高程资料进行相关分析，建立水深遥感信息的定量模式，结果表明：具有高分辨率的ＳＰＯＴ卫星资料在水下地形高程数据的支持下，通过计算机图像分析处理能够快

Application of SPOT Satellite Data to the Study of Water Depth Information

According to the characteristics of satellite remote sensing data,on the basis of the analysis result of spectral measurement made on the surface water body of rivers, lakes and reservoirs in different areas, the underwater topographic and water depth information of Wuchang lake in Anhui Province from SPOT satellite multi band image data, is processed by use of ERDAS IMAGINE software and the underwater topographic map of Wuchang lake is obtained. Correlation analysis is made for the quasi synchronously measured underwater topographic elevation data and a quantitative model of remote sensing water depth information is established. The result indicates that it is possible to use high resolution SPOT data and GIS technology to obtain water depth information.
