Latest comment: 2 years ago by Periegetes
How should the classification go? Hydrographers are person who are measuring bodies of water and making nautical charts. This category contains what to me looks like hydrological maps. Is hydrographic maps and nautical chart a same or a different thing? --Periegetes (talk) 11:38, 29 November 2021 (UTC)
