We're looking for an equivalent of "The National Waterway Network" dataset but for the entire world. Essentially vector data of all non-ocean waterways including major rivers etc, that can be used for ships. So this would exclude waterways like streams and drainages shown in typical hydro data. Anyone aware of a source for this data either as a whole or a compilation of the sources for each specific country?
Ideally the worldwide data would have some sort of uniformity between countries.
