Mapping the world's inland waters.
The depth and volume of inland waters is not well known. There are a few ways to estimate depth or volume,
but they suffer from large uncertainty.
Bathybase is a single, organized, open collection of bathymetric data. Anyone can
contribute. Anyone can access.
Data are all freely available.
There is bathymetry data for 1322 lakes.
