            COMMISSION IMPLEMENTING REGULATION (EU) No 909/2013
of 10 September 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


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Directive 2005/44/EC of the European Parliament and of the Council of 7 September 2005 on harmonised river information services (RIS) on inland waterways in the Community (1), and in particular Article 5, paragraph 1, point (a), thereof,

Whereas:







(1)


River Information Services (RIS) should be developed and implemented in a harmonised, interoperable and open way.












(2)


The technical specifications for the electronic chart display and information system for inland navigation (Inland ECDIS) should be defined.












(3)


The technical specifications for Inland ECDIS should be based on the technical principles set out in Annex II to Directive 2005/44/EC.












(4)


The technical specifications should take due account of the work carried out by relevant international organisations, notably the Resolution 48 ‘Recommendation on electronic chart display and information system for inland navigation (Inland ECDIS)’ adopted by the United Nations Economic Commission for Europe (UNECE), as well as the relevant regulations established by the Central Commission for the Navigation of the Rhine (CCNR).












(5)


In particular, Edition 2.3 of the Inland ECDIS Product Specification for Inland Electronic Navigational Charts (Inland ENCs) and Status of Presentation Library of UNECE Resolution 48 ‘Recommendation on electronic chart display and information system for inland navigation (Inland ECDIS)’ have been adopted by UNECE, following the recommendations of the Inland ENC Harmonization Group and the Inland ECDIS expert group.












(6)


The technical specifications should also take due account of the work carried out by the expert group on Inland ECDIS which is composed of representatives of the authorities of the Member States responsible for the implementation of Inland ECDIS and official members from other governmental bodies as well as observers from the industry.












(7)


The technical specifications should correspond to the current technical state of the art. Experiences gained from the application of Directive 2005/44/EC and the technical progress should be taken into account when establishing the technical specifications. The technical specifications should take due account of the work carried out by the expert group on Inland ECDIS as well as by UNECE and CCNR.












(8)


The reference to UNECE standards in this Regulation does not create any precedent for future EU standards related to inland navigation, RIS and ECDIS. The Commission has indeed initiated an evaluation of the implementation of the RIS policy. The administrative arrangement between the Directorate-General for Mobility and Transport of the European Commission and CCNR may be extended to the elaboration of standards in the field of RIS, depending on the results of this evaluation, due to be available in 2014. Where such results are available the Commission should, if appropriate, amend accordingly this Regulation.












(9)


In accordance with Article 12(2) of Directive 2005/44/EC, the Member States should take the necessary measures to comply with the requirements laid down in this Regulation not later than 30 months after its entry into force.












(10)


The measures provided for in this Regulation are in accordance with the opinion of the Committee established pursuant to Article 7 of Council Directive 91/672/EEC of 16 December 1991 on the reciprocal recognition of national boatmasters’ certificates for the carriage of goods and passengers by inland waterway (2).












(11)


Article 12(2) of Directive 2005/44/EC foresees that the technical guidelines and specifications shall enter into force on the day following that of their publication in the Official Journal of the European Union,





HAS ADOPTED THIS REGULATION:

The chart and the radar image shall match in size, position and orientation within the limits as specified in Section 4, Chapters 3.4 and 8.3.2 of these technical specifications.












(d)


The Integrated Display shall only be presented in the head-up orientation. Other orientations are permitted in systems with an additional maritime ECDIS type approval. If such a system is used in true motion and/or north-up mode on European inland waterways, it is considered to be working in information mode.












(e)


It shall be possible for the operator to adjust the off-set values between the positions of the position sensor and the radar antenna of the vessel so that the SENC display matches the radar image.












(f)


It shall be possible to remove either the ECDIS or the radar information by a single operator action temporarily.












(g)


The vessel’s position shall be derived from a continuous positioning system of which the accuracy is consistent with the requirements of safe navigation.












(h)



Navigation mode shall provide an indication when the input from the position-fixing system is lost. Navigation mode shall also repeat, but only as an indication, any alarm or indication passed to it from a position fixing system.












(i)


The positioning system and the SENC shall be based on the same geodetic datum.












(j)


In navigation mode, the data according to Chapter 3.1(c) of this Section shall always be visible and shall not be obscured by other objects.












(k)


Information regarding the position and orientation of other vessels, gathered by other communication links than the own radar, are permitted to be displayed only if they are up-to-date (nearly real-time) and meet the accuracy that is required for the support of tactical and operational navigation. Position information of the own vessel that is received from a repeater station shall not be displayed.












(l)


As tracking and tracing information (for example AIS) of other vessels is useful for the planning of the passing, but of no use during passing itself, tracking and tracing (AIS) symbols shall not disturb the radar image during passing and shall be faded out therefore. Preferably the application shall allow the skipper to define the area where the symbol is faded out.












(m)


The presentation of the position and the orientation of other vessels by






—


a directed triangle, or










—


a true outline (to scale),




are permitted only if the heading of these other vessels is available. In all other cases a generic symbol shall be used (an octagon is recommended, a circle shall not be used for applications which are certified according to maritime standards).












(n)


Information that another vessel is carrying blue cones or lights may be displayed by a different colour of the vessel symbol. The number of the blue cones/lights shall only be displayed in the pick report.












(o)


Information on the intention of another vessel to pass on starboard (blue sign) may only be displayed on the right side of the directed triangle symbol or of the scaled shape if the heading of this vessel is available. If no heading information is available the information shall only be displayed in a direction independent form.












(p)


Information regarding the position of AIS base stations, AIS Aids to Navigation (ATON) and AIS Search and Rescue Transmitters (SART) may be displayed, if the symbols can be distinguished from other symbols (e.g. symbols 2.10 and 2.11 of IEC 62288 Ed. 1, Table A.1).

SECTION 3:   PRESENTATION STANDARD FOR INLAND ECDIS
1.   INTRODUCTION








(a)


This Presentation Standard for Inland ECDIS describes the technical specifications to be used for the presentation of Inland ECDIS data. The presentation shall take place in such a way that none of the information is lost.












(b)


This Presentation Standard is based on the document ‘S-52, Specification for Chart Content and Display Aspects of ECDIS’ of the IHO, Edition 6, March 2010, with all its Appendices and Annexes (see Appendix 1).












(c)


This Presentation Standard describes the necessary additions and clarifications to S-52 and the application of S-52 for the purpose of use in Inland ECDIS applications.












(d)


This Presentation Standard includes the reference to applicable Standards and Regulations indicated in Section 1 § 2.i.












(e)


Definitions of terms may be found in:






—


IHO-S-57, Part 1, clause 5,










—


the ‘Glossary of ECDIS-Related Terms’ in S-32 Appendix 1,










—


the ‘Glossary for Inland ECDIS’ in Section 5 of these Inland ECDIS technical specifications.








2.   THE PRESENTATION LIBRARY FOR INLAND ECDIS
S-57 data sets 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 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 Edition 3.4 of the IHO ECDIS Presentation Library (Annex A of S-52).
2.1.   Components of S-52 and Inland ECDIS Presentation Library









2.1.1.


The major components of the S-52 presentation library are:






—


a library of symbols, line styles and fill styles,










—


a colour coding scheme which includes the IHO colour tables for day, dusk and night time,










—


a set of symbology command words from which machine readable instructions can be assembled. The result is a symbology instruction, which is processed to symbolise ENC features in turn,










—


a set of conditional symbology procedures to decide the appropriate symbolisation in cases determined by the mariner’s selection (e.g. safety contour) or for complex symbols (e. g. top marks on buoys and beacons),










—


a set of look-up tables that link feature descriptions from the ENC to the appropriate symbology instructions depending on whether:






—


the link is straight forward, i.e. a direct relationship between a feature’s description and its presentation such as a buoy or a land area. In this case, the look-up table provides the symbology instruction to show a symbol, an area fill, or a line style,










—


the link is conditional, i.e. depending on circumstances, for example a depth area, whose colour fill depends on the choice of the safety contour. In this case the look-up table refers the decision to a conditional symbology procedure that selects the appropriate symbology instructions later.




















2.1.2.


Inland ECDIS shall use all S-52 components plus extensions in:






—


Lookup tables










—


Symbol library










—


Conditional symbology procedures.




The extensions are described in Appendix 2 Presentation Library for Inland ECDIS of the UNECE Resolution on Inland ECDIS referred to in Section 1 § 2.i.




2.2.   Look-up tables









2.2.1.


For each geometry type (point, line, area) there is a separate look-up table. Each entry in a look-up table consists of the following fields:






(a)


6-character code of the feature class (acronym);










(b)


Attribute combination;










(c)


Symbolisation instructions;










(d)


Display priority, 0-9 (comparable with drawing layers);










(e)


Radar code;










(f)


Display category (Display base, standard, all other);










(g)


‘Viewing group’, more refined grouping of features than the display categories.





Figure 1


Example entry of a look-up table

"LNDMRK","CATLMK17|","SY(TOWERS01)","7","O","OTHER","32250"
In this case the feature LNDMRK is shown by the symbol TOWERS01 with priority 7, if the attribute CATLMK equals 17. The feature lies over the radar.
The presentation of features in a specific area that are contained in different cells of the same usage follows the entries in the look-up tables.












2.2.2.


The Presentation Library provides five look-up tables:






—


paper chart point symbols,










—


simplified point symbols,










—


line symbols,










—


plain area boundary symbols,










—


symbolised area boundary symbols.








2.3.   Conditional symbology procedures (CS)

CS are generated for features of which the symbolisation






—


depends on application settings, e.g. safety contour,










—


depends on other features, e.g. top marks and their structure,










—


is too complex to be defined in a direct look-up table entry.




CS Procedures, which shall be modified or implemented in an Inland ECDIS additional to the CS Procedures of S-52 are described in Appendix 2 Presentation Library for Inland ECDIS of the UNECE Resolution on Inland ECDIS referred to in Section 1 § 2.i.
2.4.   Colours

Colours used in an ECDIS are defined in an absolute, monitor independent way (CIE coordinates). This ensures that ECDIS charts look similar on monitors of different suppliers. By means of a colour calibration software which must be used by the manufacturer, CIE values are converted into RGB values.
Commercial displays usual in the trade are seen as matching these requirements.
Because of the different lighting conditions on the bridge of a vessel, it is necessary to offer presentations with different brightness. For each level a separate colour table exists.
The represented colour scheme shall be chosen on the basis of ergonomically and physiological factors and the representation of indications in different colours shall not result in mixed colours by superimposing.
2.5.   Presentation of notice marks

Notice marks which are located at the river bank are presented in the chart displayed by generic symbols (notmrk01, notmrk02 and notmrk03). This does not apply to the notice marks on bridges.
Additionally applications are required to be able to display the detailed symbol, which is similar to the real world indication, and the full set of object information of a user-selected notice mark.
Notice marks that are located at bridges, shall be symbolised according to the orientation of the bridge.
Notice marks which specify distances or a velocity shall not be symbolised with the number itself, but only with that symbol which gives the general regulation or information.

4.1




North-up display


Information shown on the display (radar or ECDIS) with the north direction upward.


2




Other navigational information


Navigational Information not contained in the SENC, that may be displayed by an ECDIS, such a radar information.


2




Overscale


Displaying data at a larger scale than it was compiled for.


2




Own-vessel


The term which identifies the vessel upon which an ECDIS is operating.


2




Own vessel’s safety contour


The contour related to the own vessel selected by the mariner from the contours provided for in the SENC, to be used by ECDIS to distinguish on the display between the safe and the unsafe water, and for generating anti-grounding alarms.


2




Performance standard for ECDIS


Standard developed under the authority of IMO to describe the minimum performance requirements for navigational devices and other fittings required by the SOLAS Convention.
Adopted by IMO on 5 December 2006 and published as MSC.232(82).


2




Pick report (feature report)


The result of querying a displayed point-symbol, line or area for further information from the data base which is not represented by the symbol.


2




Presentation library for ECDIS


A set of mostly digital specifications, composed of symbol libraries, colour schemes, look-up tables and rules, linking every feature and attribute of the SENC to the appropriate presentation of the ECDIS display. Published by IHO as Annex A, Special Publication No 52 (S-52).


2




Product specification


A defined subset of the entire specification combined with rules, tailored to the intended usage of the transfer data.
(The ENC Product specification specifies the content, structure and other mandatory aspects of an ENC.)


2




(Radar) range


Distance from the radar antenna. For inland navigation the radar range has to be sequential switchable according to the CCNR Radar Regulations.


9




Relative motion display


A relative motion display shows the chart information and radar targets moving relative to the vessel position fixed on the screen.


2




Route planning


An ECDIS function in which the area is displayed which is needed to study the intended route, to select the intended track, and to mark the track, its way points and navigational notes.


1




SCAMIN


The minimum scale at which the feature may be used e.g. for ECDIS presentation.


3




SENC


System Electronic Navigational Chart: A data base resulting from the transformation of the ENC by ECDIS for appropriate use, updates to the ENC by appropriate means and other data added by the mariner. It is this data base that is actually accessed by the ECDIS for the display generation and other navigational functions. The SENC may also contain information from other sources.


2




Spatial object


An object which contains locational information about real world entities.


2




Standard display


Standard Information Density means the default amount of SENC information that shall be visible when the chart is first displayed on ECDIS.


4.1




[Vessel] Tracking and Tracing


The function of maintaining status information of the vessel and – if needed – combined with information on cargo and consignments [tracking] and
the retrieving of information concerning the whereabouts of the vessel and – if needed – combined with information on cargo, consignments and equipment [tracing].


10




True motion display


A display in which the own vessel and each radar target moves with its own true motion, while the position of all charted information remains fixed.


2




User-defined settings


Means the possibility to use and store a profile of display and operation controls-settings.


4.1




VRM


Variable Range Marker.


4.5




WGS 84


WORLD GEODETIC SYSTEM: The geodetic basis for the ‘Navigational Satellite Timing and Ranging — Global Positioning System’ (NAVSTAR-GPS), which enables the surveying of the earth and its entities and was developed by the United States Department of Defence. This global geodetic reference system is recommended by IHO for hydrographic and cartographic use.
