| 摘 要： | 海岸带浅水和底质的成分复杂且分布不均,使遥感水深探测面临很大挑战.尝试通过利用Hydrolight 仿真建立的遥感反射率半分析模型来解决这个问题.采用英属维尔京群岛彼得岛的高光谱影像,应用非线性优化的方法提取了水下地形.从反演水深和海图标注水深拟合的趋势线斜率为0.939 2,决定系数为0.825 8.试验结果证明,使...

| Abstract: | The complexity and heterogeneity of shallow coastal waters and benthic habitats provide a challenge for bathymetry using remote sensing imagery.We attempt to overcome this problem by utilizing a semianalytical model of remote sensing reflectance,generated through Hydrolight silmulation.This study applied a nonlinear optimisation methodology to retrieve underwater terrain using hyperspectral imagery of Peter Island in the British Virgin Islands.The slope of the regression line derived from the retrieved bath... |
