Auxiliary and reference charts, overviews

Overview and reference charts as well as overviews are auxiliary cartographic products, enabling users to get a general idea of navigational conditions of shipping on the Dnipro and the Danube rivers and get a wider knowledge of the World Ocean, zone time system and the nature reserve fund in the Ukrainian waters of the Black Sea and the Sea of Azov.

These are cartographic publications, having different subject matter and designation, containing information that is represented insufficiently or missing on charts, required for navigation conditions study, as well as some necessary data, which contribute to solution of navigational and other problems of applied and scientific nature. The auxiliary cartographic products are not used directly for navigation.
