基于Sentinel-1卫星的北冰洋海冰信息提取
Information Extraction of Arctic Sea Ice Based on Sentinel-1Satellite
摘要
Abstract
In order to study the distribution and morphological characteristics of Arctic sea ice over time, a long time serial images from Sentinel-1satellite are used to study the extraction and change of sea ice in the Fram channel region in this paper. After the image preprocessing, the sea ice is extracted by K-Means clustering algorithm. The distribution of sea ice is described in sea ice concentration. The morphological features of sea ice in floating ice area are characterized by area, perimeter and roundness. According to the classification of sea ice area, the variation of each parameter with time is analyzed. In addition, the relationship between the parameters and the physical process of ice breaking is studied. The results show that, based on high resolution SAR data, fine sea ice distribution can be obtained. Combining it with traditional sea ice concentration products, the multi-scale ice map with more abundant information can be constructed. It can provide support for polar sea ice monitoring. It is of great significance for maintaining the safety of Arctic waterway and analyzing the climate effect of Arctic sea ice.关键词
