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. [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

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
