Global inventory of glacial lakes (GIGLak)

Climate change accelerates the extensive retreat of glaciers, leading to the widespread development of glacial lakes. A holistic picture on the spatial distribution of glacial lakes worldwide is crucial for tracking the outburst flood hazards. By employing a semi-automated mapping approach and rigorous quality control, this study inventories global glacial lakes (≥0.01 km²) worldwide (the ice cap/sheet of Antarctic and Greenland excluded). The evaluation result shows that this global glacial lake data has an overall accuracy of 89.37% and 91.42% in number and area, respectively.
