Through the water depth information enhancing of Landsat TM image at the south branch of the Changjiang River Estuary,the wave band combination of TM4/TM2 is chosen for the development of water depth image spectral value correlation model.
通过对长江口南支水域ＬａｎｄｓａｔＴＭ遥感图像进行水深专题信息的增强处理，选择ＴＭ４／ＴＭ２波段组合，结合当地同一时期实测水下地形图资料，建立了该水域水深与影像光谱值之间的统计相关关系。
The statistical relationship between SOM content and spectral value in ASTER data was fit to a exponent equation, logarithm expression about total N and reflectance.
对黑龙江省绥化市附近黑土区范围内采集土壤样品进行研究,在ASTER遥感影像中获取对应采样点的光谱值,将土壤有机质、总氮含量和遥感影像光谱值进行逐步回归分析,得出影像反射光谱值与有机质含量之间指数关系式;与总氮含量确定为对数关系。
