摘要
通过对闽江口水下三角洲的遥感影像预处理,利用波段标准差、波段间相关性、最佳指数公式等定量方法和光谱分析法,得出TM遥感数据在闽江口水下三角洲调查中最佳波段组合为TM432,同时表明仅仅利用定量的统计参数并不能准确确定最佳波段组合,还需要结合研究对象的光谱特征。
By using remote sensing image preprocessing of the submerged delta in the Minjiang Estuary, the spectrophotometric methods and the quantitative approach such as the waveband standard deviation, inter-band relativity and optimal exponential formula, it is considered that the optimum band assembly of TM remote sensing data is TM432 in the submerged delta investigation of the Minjiang Estuary. It is shown that the optimum band assembly can not be well and truly determined merely by the quantitative statistical parameters and has need of the spectral signatures of the investigated subject.
