IC-ENC International Centre for Electronic Navigational Charts ENC Validation & Distribution Presented by Jenny Thacker Office of Coast Survey

IC-ENC’s Mission To provide low cost services to national Hydrographic Offices that ensure their ENCs are: • • • compliant to the international standards consistent across the global dataset and readily available for use so that ships can navigate safely, efficiently and confidently, while ensured that other maritime users are using the same approved data. Office of Coast Survey

What is IC-ENC? International Centre for Electronic Navigational Charts. IC-ENC is a RENC which stands for Regional ENC co-ordinating center. It is responsible for validating its members ENCs and positioning them in the market place through a selected group of Value Added Resellers (VARs). Office of Coast Survey

What is a RENC? A VAR? IC-ENC? RENCs ensure that all the ENCs that they handle are consistent. The RENCs also make ENCs available to VARs from a single wholesale source. VARs are Value Added Retailers. They are distributors of ENCs to the marketplace through which all IC-ENC members validated data passes. IC-ENC is a not-for-profit RENC that is controlled by the Member Country Hydrographic Offices that distribute HO’s ENCs through VARs. Office of Coast Survey

IC-ENC vs Primar IC-ENC Primar * Not-for-profit * For profit * Validations use both * Validation uses only software and expertise software * Checks for gaps & overlaps between member & non-member state ENCs * Provides training, other * No training, no other Both RENCs cooperate freely with each other and share information including ENC limits and how to treat various error messages.

IC-ENC’s Mission To help members make ENCs! AND to help members make better ENCs! Office of Coast Survey

How do mariners see ENCs? Mandatory requirement of SOLAS class vessels: • An Electronic Chart Display and Information System (ECDIS) which is a geographic information system used for nautical navigation that complies with International Maritime Organization (IMO) regulations as an alternative to paper nautical charts. Not sufficient for mandatory carriage requirement: • Electronic Chart System (ECS), various Portable Pilot Units (PPU), and online viewers (e. g. , NOAA ENC® Viewer) Office of Coast Survey

IC-ENC Core Services ENC Production Support ENC Distribution Office of Coast Survey ENC Validation Revenue Management & Financial Reporting

What is validation? An independent ENC quality assurance service, which is achieved through a concise and consistent approach by its team of experienced Data Validators. The Validation team operate to policies based on real and practical user experience, while assessing any issues which could impact the end user, the mariner. • Defined rules and encoding practices laid out in the S-57 and S-58 Standards. • Interpretation of the varying results of the different softwarebased validation tools. Office of Coast Survey

How do we validate an ENC? • Members upload their ENCs to IC-ENC’s home office (UK). ü ENCs are added to a Management Database (DMD) ü All New Editions and Updates are loaded to 3 separate ECDIS ü Regional validators run d. Kart, ENC Analyzer, ENC Designer checks, and custom checks • The DMD creates a Summary Report from all of the checks. • Regional validators review the Summary Report and catagorize the warnings and errors based on levels of criticalness.

IC-ENC Validation IC-ENC does not edit or modify the data provide by the HO, the ENC remains the property and responsibility of the producing nation at all times. • Software analysis and testing – Assessment of errors (d. Kart Inspector, ENC Analyzer, ENC Designer, Custom in-house checks) – ECDIS Checks (Transas, JRC, e. Globe) – Exchange set checks (DMD) • IC-ENC validation team expertise – Consistency Checks (horizontal & vertical) – Regional Knowledge – Analysis based on extensive experience Office of Coast Survey

The Validation Report • A Validation Report is produced for every validated ENC file • Created from the error classifications and decision making from validation • Reports issued back to HO • Can be tailored to the HO via the Partnership Agreement Office of Coast Survey

The “Parts“ of a Summary Report Office of Coast Survey

Where do we get the answer? IC-ENC Errors Knowledgebase What is it? How do you access it? How do you use it? What if you don’t agree with it? Office of Coast Survey

IC-ENC Knowledgebase (formerly IC-ENC Errors Database) • Now available in the Hydrographic Offices Sharepoint Site. • https: //icenctrial. sharepoint. com/hos/Lists/Knowl edgebase 20200709/Allitemsg. aspx • The NOAA login is encnoaa@outlook. com • The NOAA password is Psyg 0 s 1 s Office of Coast Survey

Who to contact? Sean Legeer and Mike Gaeta • I can’t fix this error (NOAA policy, ESRI software) • I don’t want to see this (e. g. CATZOC, SCAMIN, horizontal consistency) Jenny Thacker, Rob Ciepiela, and Martha Backry • I don’t understand something in the report / how to fix it? • I cannot change this, or this cell has to be this way weird bridge or aid configurations) • d. Kart / Analyzer is wrong (software changes needed) • Knowledgebase is wrong Office of Coast Survey (e. g. ,

New Errors and Warnings Validation tools are continually updated • Analyzer - Version: 4. 0. 1 Build 7 • d. Kart – Version 6. 4. 0. 3349 • Designer – Version 4. 7. 0. 14 Office of Coast Survey

HO TO CHECK? Elements of a Validation Report Office of Coast Survey

Errors that aren’t errors • Critical error - [FE-001123] DAYMAR CRITICAL LG 0113: (T 0054 b) object is not covered by a mandatory 'object' <Daymark> -- 41° 31'08. 25"N : 82° 56'07. 44"W • What IC-ENC is doing • How are these errors being treated now? • What should NOAA do? Office of Coast Survey

Improvement Success • Critical FORMAT errors VS 57_ERR_ATT_FORMAT The value of ' 20060500' for attribute SORDAT is invalid. Expected format CCYYMMDD | CCYYMM | CCYY. S 57 Reference: S-57 Appendix A, Ed. 3. 1; S-58 Ed. 5. 0: checks 26 b, 542 and 557 FE 0000000110 Feature Type: BUAARE Built-up area • Why it needed to be fixed promptly • How we fixed it • Follow through Office of Coast Survey

Another Success • Critical DRVAL 1 = DRVAL 2 - [FE-001490] DEPARE CRITICAL LG 0053: (T 1779) 'drval 1' equal to 'drval 2' <Depth area> - Edge [VE-0000000425] ERROR LG 0057: (T 1771) depth contour does not correspond to depth area limit VS 57_UOC_140 If the feature is a DEPARE and the spatial type is area, then the value of DRVAL 1 must not be the value of DRVAL 2. S 57 Reference: S-57 Appendix B. 1 - Annex A Ed. 4. 0. 0: 5. 4; S-58 Ed. 5. 0: check 177 FE 0000001518 Feature Type: DEPARE Depth area • Why is it important? • What can we do about it? • How are these errors being treated now? Office of Coast Survey

Another Success • Point pylons without land area under them The story • Used to be necessary for all pylons because pylons turned off when ECDIS was in Basic mode – that’s been fixed • Error removed from S-58 checks for point objects but not from Seven C’s software • NOAA cartographers discovered the difference between Seven C’s and S-58 – they showed IC-ENC • IC-ENC used its 45 member nation clout to make Seven C’s fix the error in the next version of Analyzer Office of Coast Survey

Improvements in Progress • Caution Area Limit errors [FE-000740] CTNARE Warning LG 0079: (T 1806) 'ctnare' object shares geometry with 'depcnt' <Caution area> VS 57_UOC_162 If the feature is a CTNARE, then it should not be bordered by a DEPCNT of line geometry. S 57 Reference: S-57 Appendix B. 1 - Annex A Ed. 4. 0. 0: 6. 6; S-58 Ed. 5. 0: check 1806 FE 0000000740 Feature Type: CTNARE Caution area • Why it needed to be fixed promptly • How we fixed it • Follow through Office of Coast Survey

New Critical Error • Hazard encoded between Group 1 Objects - [FE-001090] WRECKS CRITICAL LG 0369: (T 1804) Hazardous Object wrecks [FE-001090] is on the edge between group 1 objects. <Wreck> -- 38° 56'39. 61"N : 74° 58'19. 46"W • What does this mean? • Why is it critical? • How do we fix it? • How do we find this problem? It’s in d. Kart not Analyzer. Office of Coast Survey

Legacy Issues • Density warnings VS 57_ERR_VERTEX_DENSITY Edge contains one or more vertices whose distance from neighbouring vertices is less than 0. 3 mm at compilation scale. S 57 Reference: S-57 Appendix B. 1 Ed. 2. 0, 3. 8: S-58 Ed. 5. 0: check 571 VE 000005 • Why is it important? • How do we fix it? • How are these errors being treated now? • NOAA is more critical than IC-ENC Office of Coast Survey

Helping to Shape Policy • Rocks Awash that go too far above datum – What is the current policy? • US: Pacific +/-2 ft; Atlantic +/-1 ft • IHO: +/- 0. 1 m – Why is it important? – What can we do about it? – How are these errors being treated now? Office of Coast Survey

Communicating with other countries If an IC-ENC member has an overlap / gap issue with another country IC-ENC can help Example 1: • US wanted to produce a band 3 ENC in Haiti but the Cubans had a cell there. • The US and Cuba negotiated an agreement • The US tried to release our cell, but the Cuban’s had to release theirs on the same date and the US could not reach them. • IC-ENC reached the Cubans for the US and distributed both cells on the same day Office of Coast Survey

Example 2 • IC-ENC provided cell extents to a member country prior to a meeting with an adjacent country to discuss resolving overlap issues with multiple cells between the two countries. • “We have had zero luck in the past trying to get this information from the [country] themselves”. • An agreement was reached. • ENC cells were cut to eliminate the overlaps. • Seamless coverage was achieved.
