Global Salt Marsh Change, 2000-2019

This dataset provides global salt marsh change, including loss and gain for five-year periods from 2000-2019. Loss and gain at a 30 m spatial resolution were estimated with Normalized Difference Vegetation Index (NDVI) anomaly algorithm using Landsat 5, 7, and 8 collections within the known extent of salt marshes. The data are provided in cloud-optimized GeoTIFF format.本数据集详尽地提供了全球范围内盐沼的变化情况，涵盖2000年至2019年间的五年期损益数据。通过运用归一化植被指数异常算法（Normalized Difference Vegetation Index, NDVI anomaly algorithm），并结合Landsat 5、7和8号卫星影像，在已知盐沼范围内，以30米的空间分辨率对损益进行了估算。数据以云优化GeoTIFF格式提供。
