全球地表水覆盖(Global Surface Water)是利用1984至2019年获取的landsat5、landsat7和landsat8的卫星影像,生成分辨率为30米的一套全球地表水覆盖的地图集。用户可以在全球尺度上按地区回溯某个时间上地表水分的变化情况。该数据集包含 change为全球地表水体变化程度,它提供了1984-1999年和2000-2019年间地表水发生增加、...
Global surface water products from the European Commission Joint Research Centre, based on Landsat 5, 7, and 8 imagery. Layers in this collection describe the occurrence, change, and seasonality of surface water from 1984-2020. Complete documentation for each layer is available in theData Users ...
JRC Global Surface Water Mapping Layers产品,是利用1984至2020年获取的landsat5、landsat7和landsat8的卫星影像,生成分辨率为30米的一套全球地表水覆盖的地图集。用户可以在全球尺度上按地区回溯某个时间上地表水分的变化情况。产品由包含7个波段的图像组成,反映了过去35年间地表水在空间和时间的分布情况。 前言 –...
Natural variability in surface water storage is greatest in tropical basins, whereas human-managed variability is greatest in the Middle East, southern Africa and the western USA. Strong regional patterns are also found, with human influence driving 67 per cent of surface water storage variability ...
We calculate the change in surface water coverage within each catchment before and after dam completion. This allows us to understand how the dam has inundated the surrounding land. We use data from the Global Surface Water (GSW) Explorer developed by the European Commission Joint Research Centre...
They are either based on visible imagery from Landsat-the Global 3-second Water Body Map (G3WBM) and the Global Surface Water Explorer (GSWE)-or on the merging of passive/active microwave and visible observations-Global Inundation Extent from Multi-Satellite (GIEMS-D3)-that has been down...
Water Explorer by Chris Arderne was a site for visualizing upstream and downstream areas with HydroSHEDS data, but he turned it off in order to stop paying for the hosting service. The Ocean Cleanup's Plastic Tracker: enter a location, then follow the flow path to see where a piece of pl...
《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...
Observations by the Lunar Prospector and the Lunar Atmosphere and Dust Environment Explorer spacecraft suggest the existence of a near-global deposit of weakly bound water ice on the Moon, extending from a depth of a decimetre to at least three metres. The existence of such a layer is puzzling...
This study is based on the Global Surface Water Explorer (GSWE) dataset, a global database derived from the analysis of over 3 million satellite images that maps water presence over 32 years29. This dataset was analyzed for changes in water presence along more than 2 million virtual transect...
