ENC versus Inland ENC
Definition Inland ENC Database, standardized as to content, structure and format, for use with inland electronic chart display and / or information systems operated on board of vessels transiting inland waterways. An IENC is issued by or on the authority of a competent government agency, and conforms to standards [initially] developed by the International Hydrographic Organization (IHO) and [refined by] the Inland ENC Harmonization Group. An IENC contains all the chart information necessary for safe navigation on inland waterways and may contain supplementary information in addition to that contained in the paper chart (e.g. sailing directions, machine-readable operating schedules, etc.) which may be considered necessary for safe navigation and voyage planning.

Navigational purposes ENC IENC
Minimum Content IENC Minimum Contents of an IENC At a Minimum, the following objects shall be included in an IENC: 1. Bank of waterway 2. Shoreline construction (e.g., groin, training wall) 3. Any facility that is considered a hazard to navigation 4. Contours of locks and dams (i.e., footprint area) 5. Boundaries of the navigation channel (if defined) 6. Isolated dangers in the navigation channel that are either: a) under water (obstructions) b) above water level (e.g., bridges, overhead cables) 7. Official Aids-to-Navigation (e.g. buoys, beacons, lights, notice marks) 8. Waterway axis with kilometres/hectometres, or river miles

Competent authorities assigned by the MS When? within 30 months after the publication of the technical guideline for Inland Ecdis source:iehg: ienc.openecdis.org

RIS index Location code (ISRS code): unique ID for each piece of infrastructure 20 digit alphanumerical code (UNLOCODE): BEBGS07401L020400000 The RIS Index describes several RIS objects on waterways (such as junctions, locks, bridges, berths, gauges etc). Countries applying RIS are obliged to identify the objects RIS Index Encoding Guide version v0.8 (December 2010) need to develop a European wide encoded harmonized list of objects
