摘要:

依据不同围填海类型在高分三号(GF-3)合成孔径雷达(synthetic aperture radar, SAR)卫星遥感影像上可分性, 建立围填海遥感分类体系及相应的围填海类型解译标志, 进而分析SAR图像岸线提取方法, 构建GF-3围填海监测技术流程。采用几何主动轮廓模型进行GF-3 SAR影像自动提取海岸线, 获得围填海专题图。通过外业精度调查验证GF-3 SAR卫星遥感影像可以有效获取围填海信息。

Abstract:

GF-3 (Gaofen-3) is the first earth observation satellite to be equipped with a full polarimetric synthetic aperture radar (SAR) imaging sensor, which provides the capability for dynamic national marine monitoring. Based on the separability of the reclamation categories in SAR images, in this study, we establish a land reclamation classification system and interpret marks associated with the corresponding reclamation categories. In addition, we apply and analyze various coastline extraction approaches with respect to SAR imagery and establish a flowchart for the reclamation monitoring process. We adopt the geometric active contour model to automatically extract the coastline from GF-3 SAR imagery and use reclamation-change range information to generate a thematic map for GF-3 SAR images. Our field survey results demonstrate that GF-3 SAR remote sensing imagery can be effectively used to obtain reclamation information.
