The German Hydrographic Society (DHyG) is a professional association that promotes the interests of hydrography and sees itself as the mouthpiece of hydrographers. Since 1984, DHyG has been promoting practical and scientific hydrography as well as national and international cooperation. The DHyG offers a forum of regular professional exchange to all interested parties.
Once a year it organizes a conference: the Hydrographentag. In addition, it publishes the Hydrographische Nachrichten three times a year, the only German-language journal for hydrography and geoinformation.
