Defra and JNCC Sentinel-2 Analysis Ready Data (ARD)

These data have been created by the Department for Environment, Food and Rural Affairs (Defra) and Joint Nature Conservation Committee (JNCC) in order to cost-effectively provide high quality, Analysis Ready Data (ARD) for a wide range of applications. The dataset contains modified Copernicus Sentinel-2 (Level 1C data processed into a surface reflectance product (Level 2)). Defra and JNCC data were processed on separate platforms using a common specification to produce complementary outputs.

The majority of data captured between July 2015 and August 2017 was processed by Aberystwyth University for Defra and later updated by JNCC to the same specification as the rest of this dataset. Please see the image-level metadata for details of data lineage and processing.

本数据集由环境、食品和农村事务部（Defra）及联合自然保护委员会（JNCC）联合创建，旨在以成本效益的方式提供高质量、分析准备数据（ARD），以满足广泛的应用需求。数据集包含经过修改的哥白尼哨兵-2（Copernicus Sentinel-2，Level 1C数据经处理转化为地表反射率产品，Level 2）。环境、食品和农村事务部及联合自然保护委员会的数据分别在不同平台进行处理，遵循统一规范，以产生互补输出。2015年7月至2017年8月间捕获的大多数数据由阿伯里斯特威斯大学（Aberystwyth University）代表环境、食品和农村事务部进行处理，并由联合自然保护委员会（JNCC）更新至与该数据集其他部分相同的规范。请参阅图像级元数据，以获取数据源流和处理的详细信息。
