基于Landsat 8的世界各国南极内陆考察特征分析
|
摘要
利用南极地区夏季Landsat 8卫星短波红外影像获取近年世界各国南极内陆考察车辙印、机场跑道、中转站等考察足迹信息.一方面,深入分析我国南极考察内陆考察路线特征,并通过相邻3个年度南极考察内陆考察轨迹对比了解考察轨迹的变化特点;另一方面,对比分析世界各国内陆考察起止点、中转站和路线轨迹差异,并结合南极冰上、冰下地形数据,冰雪积累率和冰流速等辅助数据,探索各国南极考察路线特征,通过对各国南极内陆考察活动和路线断面特征的对比分析,了解世界各国的极地考察水平.
Landsat 8 satellite can be used to obtain footprints of human Antarctic expeditions such as tracks of rut,airport runway and transfer station,to helps plot route of inland inspection.Analysis of Antarctic Survey route and analysis of ancillary data(Antarctic ice and snow accumulation rate and ice velocity)were combined to characterize land survey and cross route sections of Antarctic countries.Effective information was obtained to formulate future development plan for Antarctic scientific expedition from China.
