Harmonized Landsat Sentinel-2(HLS)是一种卫星数据产品,通过整合Landsat和Sentinel-2卫星的观测数据,创...
HLS数据介绍 https://hls.gsfc.nasa.gov/ https://lpdaac.usgs.gov/data/get-started-data/collection-overview/missions/harmonized-landsat-sentinel-2-hls-overview/ Harmonized Landsat Sentinel-2 (HLS) 是 NASA 的一项举措,输入产品是 Landsat 8-9 L1 和 Sentinel-2 L1C 大气层顶部反射率。该数据自2013年4...
HLS还包括来自Landsat 8 TIRS传感器的两个热红外波段在L30产品中 - 这些值没有经过大气校正,但是重新调整了表观亮度温度(无大气层,单位辐射率)。 空间配准 我们在HLS中的目标是保持Sentinel-2图像的大地测量精度要求(<20米误差,2σ),并改善Sentinel-2图像之间以及Sentinel-2和Landsat 8图像之间的多时相配准(<15...
HLSS30和HLSL30产品是基于这两种卫星的数据,具有相同的30米空间分辨率,采用MGRS网格,并支持时间序列分析。HLS的核心优势在于提升了时间分辨率,相较于单独的Landsat或Sentinel数据,提供了更频繁的更新,自2013年起便开始提供服务。产品经过辐射校准并重采样至统一的30米分辨率,以Sentinel-2的MGRS UTM网格...

The combination of Landsat and Sentinel-2 data offers a unique opportunity to observe globally the land every 2-3 days at medium (<30m) spatial resolution. The Harmonized Landsat-Sentinel-2 (HLS) project is a NASA initiative to produce a consistent, harmonized surface reflectance product from La...
At the same time, the large combined data volume from Landsat 8 and Sentinel-2 introduce substantial new challenges for users. Land surface phenology (LSP) algorithms, which estimate the timing of phenophase transitions and quantify the nature and magnitude of seasonality in remotely sensed land ...
