# Commission Implementing Regulation (EU) 2018/1973 of 7 December 2018 amending Implementing Regulation (EU) No 909/2013 on the technical specifications for the electronic chart display and information system for inland navigation (Inland ECDIS) referred to in Directive 2005/44/EC of the European Parliament and of the Council, Division 2: THE PRESENTATION LIBRARY FOR INLAND ECDIS

Extent: E+W+S+N.I.

S-57 data sets describe the data standard for Inland ENCs, however, they do not contain any information about how the data is going to be presented. The chart presentation is generated online in the Inland ECDIS application. For that purpose, the Inland ECDIS application uses machine-readable symbolisation instructions for each feature, which is drawn on the screen. For the presentation of ENCs the IHO S-52 standard is mandatory. The S-52 standard contains all rules which are necessary for the symbolisation and presentation of ENCs on the screen.
Since the features, attributes and attribute values for ENCs were extended for Inland ENCs and bathymetric Inland ENCs, an extension of the S-52 standard is necessary in order to be able to display also the Inland specific features. All extensions apply to the document referred to in the fourth indent of point 2(c) of Section 1 of this Annex.
