《High-resolution mapping of global surface water and its long-term changes》这篇文章介绍了全球地表水的制作。也就是我们在GEE常用的数据集JRC,今天我们以年度数据为例进行一些研究。 01 摘要 地表水(内陆和沿海)的位置和持久性都受到气候和人类活动的影响,并影响气候、生物多样性和人类福祉。记录地表水位置和...
A freely available dataset produced from three million Landsat satellite images reveals substantial changes in the distribution of global surface water over the past 32 years and their causes, from climate change to human actions. The distribution of sur
