北美苔原和北方森林的高分辨率水体数据集
前言 – 床长人工智能教程
这代表了北美高纬度地区的水体数据集（WBD-NAHL）。确定了近650万个水体，其中约有600万个（∼90％）小于0.1平方公里。该数据集提供了每个水体的面积和形态属性。在这项研究中，我们开发了一种自动检测地表水范围和识别10米分辨率Sentinel-2多光谱卫星数据中的水体的方法，以提高划定小水体及其形态属性的能力。该方法被应用于2019年获得的Sentinel-2数据，以产生北美整个苔原和寒带森林的水体数据集。该数据集比北美现有的区域数据集，如永久冻土区池塘和湖泊（PeRL），提供了一个更完整的代表区域。通过与整个地区随机取样地点的解释数据进行比较，WBD-NAHL数据集检测到的水体范围的总精度为96.36%。原始数据来源是国家青藏高原/第三极环境数据中心。
