Division 3.1 Contents and provision of Inland Electronic Navigational Charts (Inland ENCs) and bathymetric Inland ENCs

The chart information to be used in Inland ECDIS shall be the latest edition of information.

Provisions shall be made to prevent the user from altering the contents of original Inland ENC and bathymetric Inland ENC editions.

At least the following features shall be included in the ENC:

• links to the external xml-files with operation times of restricting structures, in particular locks and bridges.

• location of ports and transhipment sites,

• reference data for water level gauges relevant to navigation,

• shoreline construction (e.g. groin, longitudinal control dam, training wall – any facility that is considered a hazard to navigation),

• contours of locks and dams,

• boundaries of the fairway/navigation channel (if defined),

• isolated dangers in the fairway/navigation channel under water,

• isolated dangers in the fairway/navigation channel above water level, such as bridges, overhead cables etc.,

• official aids-to-navigation (e.g. buoys, beacons, lights, notice marks),

If the chart producer is using overlay files or bathymetric Inland ENCs, the features may be included in different chart cells, but the whole package must fulfil the minimum requirements listed in the indents above.

Where the chart is intended to be used for navigation mode (Chapter 5.2 of this Section), the respective competent authority shall decide for each waterway or harbour which of the features referred to in point (c) are to be verified. After verification, the respective competent authority shall declare which Inland ENCs and bathymetric Inland ENCs are approved for navigation mode within its geographical area of responsibility (for details see Section 2A of this Annex).

The System Electronic Navigational Chart (SENC) shall be stored in the Inland ECDIS.
