哨兵卫星Sentinel-2A数据特性及应用潜力分析
|
摘要
Sentine l-2A是欧洲航天局"哥白尼"计划下多光谱成像任务的首颗卫星,其有效荷载为拥有13个谱段的多光谱成像仪(MSI)。简要介绍了Sentinel-2A卫星的特点、轨道参数和成像模式,并与其它常用的光学卫星(Landsat8、SPOT-7、GF-1)进行了对比,同时介绍了Sentinel-2A的不同等级的产品及产品的获取方式。最后详细介绍了国内外学者利用Sentinel-2A数据在土地覆盖监测、生物量预估和风险灾害等领域的实际应用,并对其今后的应用潜力进行了讨论和展望。
Sentinel-2 A is the first satellite of the European Space Agency Copernicus program with multispectral imaging.The effective load is multispectral imager(MSI) with 13 spectral segments ranging from visible light to near-infrared to short-wave infrared.The characteristics, orbital parameters and imaging mode of Sentinel-2 A satellite are introduced.It also compares the Sentinel-2 A satellite with Landsat-8, SPOT-7 and GF-1.At the same time, it introduces the products of different grades and the way of obtaining them.Finally, the applications of Sentinel-2 A data in land cover monitoring, biomass estimation and risk disaster are introduced in detail, and its application potential in the future is prospected.
