GF-3号SAR卫星遥感围填海监测方法研究——以大连金州湾为例
Marine reclamation monitoring approach research based on GF-3 remote sensing image: A case study of the Jinzhou Bay in Dalian
摘要
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 clas-sification system and interpret marks associated with the corresponding reclamation categories. In addition, we ap-ply 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.关键词
