摘要

以蓬莱西海岸西庄至栾家口岸段作为研究区,利用机载成像高光谱数据,对比航空垂直影像图和野外调查结果,通过分析砂质、黑泥砂质和黄泥砂质3种海岸类型的光谱特征,建立分类识别模型,完成了对3种海岸类型的分类处理,确定出湿滩和干滩范围,并进一步提取出高潮潮位线和低潮潮位线。
In this paper,a classifiction and identification model based on the airborne imaging hyperspectral data is used to study the Penglai coast from Xizhuang to Luanjiakou,and the classified information processing of 3 types of coast(sandy coast,sandy coast with black mud and sandy coast with yellow mud) is then made by comparing with the vertical aerial photographs and field inverstigation results and analyzing the spectral characteristics of 3 types of coast.Finally,the wet and dry beach scopes can be identified,and the high water mark and low water mark are then extracted.
