3D-LAKES: A Three-Dimensional Global Lake and Reservoir Bathymetry Utilizing ICESat-2 Altimetry and Landsat Imagery

This study introduces the 3D-Global Lakes (3D-LAKES) dataset, which includes the area-elevation (A-E) relationship and three-dimensional bathymetry for 510,530 global lakes and reservoirs, representing 98.9% of global surface water storage capacity. In this Zenodo, Level 1 (L1) and Level 2 (L2) A-E relationships are provided. L1 products were created using ICESat-2 and Landsat satellites, while L2 products, apply interpolation and extrapolation to L1 products, may contain errors. For detailed structure and format information, please read the "README" file included in the repository.

Furthermore,

You can view the A–E relationships and 3D bathymetry maps interactively through the Google Earth Engine (GEE) application. Please visit this link.

For downloading the 3D Bathymetry maps, please visit either the Google Earth Engine (GEE) code or the Python version of the code.

For detailed methodology and validation, see Huang (2025)*.
