Resolutions and Obligations related to ENCs and ECDIS SOLAS V/2 – Nautical chart or nautical publication is a special-purpose map or book, or a specially compiled database from which such a map or book is derived, that is issued officially by or on the authority of a Government, authorized Hydrographic Office or other relevant government institution and is designed to meet the requirements of marine navigation*. SOLAS V/9 - provision of hydrographic services. . . collection and compilation of hydrographic data and the publication, dissemination and keeping up to date of all nautical information necessary for safe navigation Means: surveying and data collection publication of charts and nautical publications chart maintenance, updating providing Maritime Safety Information (MSI)

Resolutions and Obligations related to ENCs and ECDIS UN Resolution A/58/240 • “Invites the International Hydrographic Organization and the International Maritime Organization to continue their coordinated efforts, to jointly adopt measures with a view to encouraging greater international cooperation and coordination for the transition to electronic nautical charts and to increase coverage of hydrographic information on a global basis, especially in areas of international navigation and ports and where there are vulnerable or protected marine areas. ” IMO Resolution A. 958(23) • “Invites Governments, in addition to their existing obligations under SOLAS Regulation V/9, to promote through their national maritime administrations, the use of ECDIS together with the use and further production of official ENCs. ”

ECDIS Implementation Phases 63

Free Data Distribution • NOAA ENCs are “Free on the web” • Get the ENC data in the most hands, end users and developers

ENC Data • Integrating data from different sources – Inshore depth areas & obstructions – New channel information – Updated Aids to Navigation

High Accuracy Source • Digital Shoreline • NOAA Hydrographic Surveys • USACE Dredge Surveys

Application examples • Open. CPN • Open. Sea. Map • Sea. Clear II 67

Open. CPN http: // opencpn. org • Open. CPN is a free software (GPLv 2) project to create a concise chart plotter and navigation software, for use underway or as a planning tool. • Open. CPN is developed by a team of active sailors using real world conditions for program testing and refinement. 68

Open. Sea. Map - The free nautical chart 70

Open. Sea. Map Resources • Open. Street. Map database • Ports from the World Port Index, Open. Street. Map and Skipper. Guide. The water depths were rendered from GEBCO data. • Weather data were taken from the NOAA. • Lighthouses were found in the List of Lights and Open. Street. Map. • The links to Wikipedia are from Wikipedia and images from Wikimedia Commons. • The DE gauge data came from Wasser- und Schifffahrtsverwaltung (PEGELONLINE), • The CH ones from Bundesamt für Umwelt, Abteilung Hydrologie. The aerial photographs are from Bing. • AIS data were provided by Aegean University and ship tracking date by INTERMAR and Sat. Pro. • Inland waterway data in DE are provided by Wasser- und Schifffahrtsverwaltung des Bundes (WSV). • The height data (ASTA GDEM) is a product from METI and NASA provided by Open. Map. Surfer of Uni Heidelberg. • Depth data are collected by Crowdsourcing and computed, or are provided by third parties, e. g. from Bundesamt für Seeschifffahrt und Hydrographie (BSH). The data are stored on Linux servers in a Postgres/Post. GIS database and rendered with Mapnik or Osmarender and illustrated with Open. Layers. 71

Sea. Map. Editor: JOSM and Plugin Login Editor Seamark Harbour Window Editing entry 'JOSM' is a powerful tool to edit all elements of the map with high precision. A 'plugin' helps you add nautical information to be rendered on the Open. Sea. Map overlay. Seamark objects are chosen from drop-down menus and specifications can be entered manually. Only choices relavent to objects will be shown. A validity check will be performed before saving. Installation 1. install JOSM The JOSM editor is installed from the Open. Street. Map 2. install Sea. Map. Editor plugin 3. install seamark images Login In order to edit the map, you must register a user account. 73
