RADD森林扰动警报
RADD - RAdar for Detecting Deforestation - 基于Sentinel-1的10米空间尺度的湿润热带森林的近实时干扰。南美洲(13个国家)、中美洲(6个国家)、非洲(25个国家)、东南亚岛国(5个国家)和太平洋(1个国家)的原始湿润热带森林。前言 – 人工智能教程你可以在瓦赫宁根大学找到更多信息
RADD Forest Disturbance Alert - WUR
哨兵1号的穿云雷达为热带地区持续提供每6至12天的无间隙观测。在云层密集的热带地区,这对于快速检测小规模的森林干扰,如自给自足的农业和选择性采伐,是一个重大的优势。RADD(RAdar for Detecting Deforestation)警报有助于世界资源研究所的全球森林观察倡议,提供及时和准确的信息,以支持可持续森林管理和打击非法砍伐森林的执法活动中的广泛的利益相关者。RADD警报是在谷歌地球引擎中实现的。RADD警报可通过谷歌地球引擎、全球森林观察平台、SEPAL.io、EarthMap.org和Nusantara Atlas公开获得。
