GLOBathy（全球湖泊测深数据集）
前言 – 床长人工智能教程
我们开发了一个新颖的GLObal水深测量（GLOBathy）数据集，包括140多万个水体，与完善的全球数据集HydroLAKES保持一致。GLOBathy使用一个基于GIS的框架，根据水体的最大深度估计和HydroLAKES水体的几何/地球物理属性来生成水深图。最大深度估算在1503个水体中得到了验证，利用了几个观测数据源。
我们还提供了HydroLAKES水体的水头-面积-体积（h-A-V）关系的估计，这些估计来自GLOBathy数据集的测深图。h-A-V关系为全球水体系统的水平衡和水文研究提供了重要信息。你可以在这里阅读论文全文
