# Welcome Welcome to the website of the IEHG. ![](/files/-M4Tnsf1xYwJ0_irx2bW) Based on the findings of the European transport R\&D project INDRIS (Inland Navigation Demonstrator for River Information Services) and the German project ARGO in 2001, both the Danube and the Rhine Commissions adopted an Inland Electronic Chart Display and Information Systems (ECDIS) standard for Inland Electronic Navigational Chart (IENC) data and system requirements for the Rhine and the Danube Rivers. In 2001, the Economic Commission for Europe of the United Nations (UNECE) adopted the Inland ECDIS Standard as a recommendation for the European inland waterway system. The Central Commission for Navigation on the Rhine (CCNR) followed in 2002. In 2003 the European R\&D-project COMPRIS (Consortium Operational Management Platform River Information Services) organized a North American - European Inland ENC Workshop. One key objective was to discuss the benefits of harmonizing Inland ENC data standards between Europe and North America. The Inland ENC Harmonization Group (IEHG) was formed in 2003 to facilitate the development of international standards for Inland ENC data. {% hint style="info" %} The top menu helps you to navigate through the different content related to the IEHG.

The [discussion forum of IEHG](https://github.com/orgs/IEHG/discussions) is used as a sharing portal for the members. Following the link you can sign in and follow the discussions or submit a change request. # About IEHG The Inland ENC Harmonization Group (IEHG) was formed in 2003 by North America and Europe to facilitate the development of international standards for Inland ENC data. Russia has joined the IEHG soon after that and Brazil in 2007, China in 2009, South Korea in 2010, Venezuela and Peru in 2011. The IEHG is comprised of representatives from government, industry and academia. European participants take part on behalf of the Temporary Working Group Inland ECDIS of the European Committee for drawing up standards in the field of inland navigation (CESNI), the former European Inland ECDIS Expert Group. The North American participants are members of the North American Inland ENC Ad Hoc working group that was formed in 2002. The IEHG meets normally once per year. However, most of the work is accomplished via e-mail correspondence. There is a discussion forum based on github: \ \ Each new discussion has to be assigned to one of three topics: general discussions on Inland ENCs, formal Change Requests or polls. Every new contribution is notified by e-mail to the users that have enabled notifications in their github settings. The goal of the IEHG is to agree upon specifications for Inland ENCs that are suitable for all known inland ENC data requirements for safe and efficient navigation for European, North and South American, Asian and Russian Federation inland waterways. However, it is intended that this standard meet the basic needs for Inland ENC applications, worldwide. As such, the Inland ENC standard is flexible enough to accommodate additional inland waterway requirements in other regions of the world. IEHG is recognized as a Non-Governmental International Organization (NGIO) by the [International Hydrographic Organization (IHO)](https://iho.int/en/). ### History Based on the findings of the European transport R\&D project INDRIS (Inland Navigation Demonstrator for River Information Services) and the German project ARGO in 2001, both the Danube and the Rhine Commissions adopted an Inland Electronic Chart Display and Information Systems (ECDIS) standard for Electronic Navigational Chart (ENC) data and system requirements for the Rhine and the Danube Rivers. In 2001, the [Economic Commission for Europe of the United Nations (UNECE)](http://www.unece.org/info/ece-homepage.html) adopted the Inland ECDIS Standard as a recommendation for the European inland waterway system, the [Central Commission for Navigation on the Rhine (CCNR)](https://www.ccr-zkr.org/10000000-en.html) in 2002. In the USA, following a 1999 recommendation by the National Transportation Safety Board, the [U.S. Army Corps of Engineers (USACE)](https://www.usace.army.mil/) initiated a program to facilitate the production and implementation of Inland ENCs on major river and inland waterway systems in the United States. While there are some differences between the North American and European inland waterways, there are far more similarities. A North American - European Inland ENC Workshop was held in 2003 in conjunction with a Conference on River Information Services (RIS) organized by the European R\&D-project COMPRIS (Consortium Operational Management Platform River Information Services). In addition to informing participants on the status of standards development and projects being conducted, a key objective was to discuss the benefits of harmonizing Inland ENC data standards between Europe and North America. The North American - European Inland ENC Harmonization Group (IEHG) was formed in 2003 to facilitate the development of international standards for Inland ENC data. The IEHG is comprised of representatives from government, industry and academia. European participants take part on behalf of the European Inland ECDIS Expert Group, which is replaced by the temporary working group CESNI/TI/Inland ECDIS in 2020. The North American participants are members of the North American Inland ENC Ad Hoc working group that was formed in 2002. The IEHG meets once per year. However, most of the work is accomplished via e-mail correspondence, this website and the [Inland ENC discussion forum](https://github.com/orgs/IEHG/discussions). The goal of the IEHG is to agree upon specifications for Inland ENCs that are suitable for all known inland ENC data requirements for safe and efficient navigation for European and North American inland waterways. However, it is intended that this standard meets the basic needs for Inland ENC applications, worldwide. As such, the Inland ENC standard is flexible enough to accommodate additional inland waterway requirements in other regions of the world. In September 2005, the Ministry of Transport of the Russian Federation became a member of the IEHG. In 2007, Brazil through its national Hydrographic Service, the Directorate of Hydrography and Navigation (DHN), joined the IEHG as the first South American country. In October 2009, the Waterborne Transportation Institute of the Ministry of Transport, Peoples Republic of China became the first member of the IEHG from the Asian region. IEHG also works closely with the [International Hydrographic Organization (IHO)](https://iho.int/en/). At the ECDIS stakeholders’ forum in 2007, IHO confirmed that compatibility with Inland ENC standards is allowed by the standards that are certified for maritime ECDIS applications. On 14 April 2009, IEHG became recognized as a Non-Governmental International Organization (NGIO) of IHO. In addition, at the 4th Extraordinary International Hydrographic Conference on 4 June 2009, IHO adopted a resolution to cooperate with the IEHG. As an NGIO, IEHG supports, advises and provides input to IHO regarding Inland ENC matters. ### **Definition of IENC (Inland Electronic Navigational Chart)** Inland Electronic Navigational Chart (IENC) means: the database, standardized as to content, structure and format, for use with inland electronic chart display and / or information systems operated onboard 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 Standards** The framework for Inland ENC standards includes: 1. Use of **IHO S-57** (Edition 3.1), including: 1. ‘Maritime’ ENC Product Specification (Appendix B1) 2. Object Catalogue (Appendix A) 3. Use of Object Catalogue (Appendix B.1, Annex A) 2. A minimum **Inland ENC Product Specification** that includes mandatory requirements for safety-of-navigation on inland waterways, worldwide. 3. An **Inland ENC Encoding Guide** that provides guidance on recommended object classes, attributes, and attribute values for encoding IENC data. 4. Inland ENC **Feature Catalogue**. 5. Establishment of an **Inland ENC domain** for additional IENC features, attributes, and enumerations that are not already contained in other domains of the S-100 registry. 6. Use of the **ienc.openecdis.org** as a means of communication. 7. Align with the **IHO S-100** Universal Hydrographic Data Model. In particular, this includes the Inland ENC domain as part of the overall S-100 Geospatial Information Registry. The current versions of IENC-related standards are published on this website. Two other Inland IENC-related standards that are not maintained by IEHG, but are used in Europe include: 1. Inland ECDIS Standard 2. IENC Presentation Library Copies of all IENC-related standards available on this website. ### **IENC Encoding Guide** The IENC Encoding Guide provides detailed guidance on what is required to produce a consistent, uniform Inland ENC. For all object classes, attributes, and attribute values that are used in conjunction with an IENC, the IENC Encoding Guide: 1. Provides a basis for its creation 2. Describes its relationship to the real-world entity 3. Provides criteria for its proper use 4. Gives specific encoding examples 5. Provides real-world and graphic examples of IENC information (portrayal) ### Minimum Contents of an IENC At a **Minimum**, the following objects shall be included in an IENC, if they exist: 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: 1. under water (obstructions) 2. 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 In addition to these minimum requirements, the Encoding Guide contains **recommended** objects, attributes and attribute values that are suitable for any Inland ENC application, worldwide. Each country or region can decide which of these recommended objects, attributes and attribute values are necessary to meet their requirements. For example, in Europe and the USA, there are different requirements for River Information Services (RIS). # IEHG meetings ### 19.

A precondition is the encoding of the depth in accordance with I.1.2 of the Encoding Guide for Inland ENCs: {% file src="/files/-LvtkihsFQPSDCoiYT64" %} Description of the standardized water level exchange format {% endfile %} {% file src="/files/-Lvtl-77\_Gm-ho0mHG7f" %} XML schema of the standardized water level exchange format {% endfile %} ### Recommended validation checks for Inland ENCs IEHG has also developed "Recommended validation checks for Inland ENCs". The following editions are available: * Recommended validation checks for Inland ENCs 1.1 (based on S-58 Edition 4.2 and Edition 2.1 of Inland ENCs) {% file src="/files/-LvtnyltcuPhjdP8AQSj" %} Recommended validation checks 1.1 {% endfile %} * Recommended validation checks for Inland ENCs 2.3 corr1 (based on S-58 Edition 4.2 and Edition 2.3 of inland ENCs) {% file src="/files/-LvtpkMhzZTsikUTD3Jd" %} Recommended validation checks 2.3 corr 1 {% endfile %} * Recommended Validation checks for Inland ENCs 2.4 rev1 (based on S-58 Edition 6.0.0 and Edition 2.4 of Inland ENCs). This version will get an official status after testing {% file src="/files/-MGJ0lS04QTG25FZTsPy" %} Recommended validation checks 2.4 rev1 {% endfile %} * Recommended Validation checks for Inland ENCs 2.5.1 (based on S-58 Edition 6.0.0 and Edition 2.5 of Inland ENCs). The draft version of edition 2.5 has been tested and some corrections have been made. This edition 2.5.1 has been adopted by IEHG. * Edition 2.5.1 contained some typos (check 1641: umtroc instead of uwtroc, check 1669: logical instead of illogical, check 1752: SEGSEQ instead of SIGSEQ, check 1806: nor intead of not, check i1504: flodoc instead of gatcon, check i1523: equal to instead of Equal to, check i1548: Wrecks intead of WRECKS). These typos have been corrected in the following version. {% file src="/files/VLcEdsK7JLMrArbs9PQY" %} Recommended Validation Checks for Inland ENCs, Edition 2.5.1, corrected {% endfile %} Recommended Validation Checks for Inland ENCs 2.6 (based on S-58 Edition 6.0.0 and Edition 2.6 of Inland ENCs). {% file src="/files/ZYiSTr7J0GRaNOTAAUHw" %} Recommended Validation Checks for Inland ENCs, Edition 2.6 {% endfile %} Recommended Validation Checks for Inland ENCs 2.6.1 (based on S-58 Edition 8.0.0 and Edition 2.6 of Inland ENCs). {% file src="/files/kWHlR0vMMstZve9ObbZZ" %} Recommended Validation Checks for Inland ENCs, Edition 2.6.1 {% endfile %} * The following Excel sheet is providing an overview of the minimum content of Inland ENCs.
