CloudSEN12 comprises different free and open datasets provided by several public institutions and made accessible by the Google Earth Engine (GEE) platform37. These include Sentinel-2A/B (SEN2), Sentinel-1A/B (SEN1), Multi-Error-Removed Improved-Terrain (MERIT) DEM38, Global Surface Water39(...
CNES, the French Space Agency, was involved in the commissioning of both Sentinel-2 satellites and is currently working in collaboration with ESA on their long-term monitoring. This paper reviews all the techniques used to ensure an absolute calibration of the 13 spectral bands to better than ...
如何下载sentinel-2数据并且做大气校正、打开图像 L2A_Process前加.\继续尝试 成功界面如下 最后新建的2级数据与处理的一级数据在同一目录下,名字有丁点不一样,1C变成了2A,切记,这个大气校正时间比较长,一定要等他校正结束!!!下面才是结束的样子...;--IMG_DATA–根据自己需要的波段分辨率选择,最后打开相应的JP2...
Table 1. State of target and environmental conditions for each acquisition. 2.4. Sentinel-2 Data Pre-Processing Sentinel-2 Level-1C and Level-2A data are downloaded after each acquisition from the Copernicus Open Access Hub. All Sentinel-2 L1C images are atmospherically corrected with the ACOLITE...
Sentinel-2 data were firstly processed from Level-1C to Level-2A surface reflectance using a Sen2Cor—ESA Sentinel-2 Level 2A processor (https://step.esa.int/main/third-party-plugins-2/sen2cor/ (accessed on 30 October 2019)). Cirrus cloud correction was done during the Level-1C to Lev...
