The charts are usually produced by the national hydrographic authorities. In Austria, these are the Supreme Navigation Authority (Oberste Schifffahrtsbehörde, OSB) and via donau. The basis for the production of charts are images taken of the areas concerned by aerial surveys, surveys or other measurement procedures. All objects have to be available in WGS 84 format (World Geodetic System). The data form the ENCs, and in combination with the object catalogue (S-57 format) and the presentation library (S-52 format) charts can be displayed.
