Backscatter - From Ping to Database

A Canadian Hydrographic Service Perspective
The Canadian Hydrographic Service (CHS) is willing to make better use of the backscatter intensity data collected with their multibeam sounding systems. All the backscatter data collected during the last 2 decades were not systematically processed and maintained, so a lot of valuable information has not been used yet and is archived on tapes and disks. The intent of CHS is to make an inventory of this data and to process it to a minimum level so that it can be made accessible to its cartographers and to the scientific community. Backscatter information can be a valuable piece of information... (read more)

Admiralty World ENC Database Expanding

The UK Hydrographic Office's Admiralty ENC and ECDIS services continue their major expansion with over 6,500 ENC cells now available worldwide and with a further 1,000 cells scheduled to be added by the end of the year.   Regular updates on the number of ENCs available worldwide indicate steady growth as contributing nations continue to increase coverage of their waters and new nations make their ENCs available.   All data received is added to the ENC database and Base or Update Exchange Sets are made available through the UKHO's Value Added Reseller (VAR) and distributed to the mariner weekly as...

Database Production for Polish Navy

The Hydrographic Office of the Polish Navy (HOPN) is making the move to a database-driven production solution with CARIS HPD. HPD will enable HOPN to update product-specific features and make customisations while maintaining the source data, providing efficiencies and ensuring improved standards of consistency. HOPN has in recent years gained experience with CARIS' database solutions when implementing CARIS Bathy DataBASE for the management of their bathymetric data. A series of visits by CARIS consultants will take place over the first quarter of the year for training and consulting to aid in implementing HPD fully into the HOPN chart production workflow....

Updated Global Maritime Boundaries Database

The 11th Edition of the Global Maritime Boundaries Database, or "GMBD," provides a concise, GIS-based, research tool containing the current state of global maritime claims, boundaries and related information mined from Law of the Sea experts, maritime analysts, the U.S. government, the United Nations, published reference books and journals and the Internet. The GMBD can be used for automated and graphical analyses related to hydrographic surveys, offshore oil and gas exploration, fisheries, telecommunications, marine minerals and mining, defence, shipping, construction, pollution, marine scientific research, marine archaeology, recreation and ocean law, among other applications. GMBD users include agencies of the United... (read more)

Maritime Boundaries Database Now Online

Marine Regions, an online standard list of georeferenced marine place names, areas, regions, marine and maritime boundaries, has been launched. It is an integration of the VLIMAR Gazetteer and the VLIZ Maritime Boundaries Geodatabase. Marine Regions is managed by the Flanders Marine Institute. The VLIMAR Gazetteer is a database with geographic, mainly marine names such as seas, sandbanks, seamounts, ridges, bays or even standard sampling stations used in marine research. The geographic cover of the VLIMAR Gazetteer is global, but was initially focused on the Belgian Continental Shelf and the Scheldt Estuary and the Southern Bight of the North Sea.... (read more)

Bathy DataBASE Emphases Bathymetric Lidar Surveys

Teledyne CARIS has released Bathy DataBASE (BDB) 4.4. This new version addresses the areas of feature generalisation and automation of product generation for chart compilation, as well as the increasing emphasis on bathymetric Lidar surveys. A collection of new techniques for generalising bathymetry in chart compilation workflows can be found in BASE Editor, which is part of the BDB suite. Point suppression and smoothing techniques help reduce the manual work associated with turning survey data into chart ready vector features. These techniques can be used in isolation or together with other bathymetric feature compilation tools to produce the best results... (read more)

Port of Melbourne Selects Bathymetrical Database

CARIS has recently completed a successful project for the provision of a bathymetrical database system for the Port of Melbourne Corporation (PoMC, Australia). PoMC conducts regular bathymetric surveys as part of its statutory obligation to provide safe and effective transit of vessels through the harbour. The project involved the integration of CARIS Bathy DataBASE and the Engineering Analysis Module into existing PoMC workflows. CARIS Bathy DataBASE is a management system for bathymetry data, with successful installations in over twenty countries. Bathymetry assets from a multitude of sources can be brought together, regardless of file size or data source and managed... (read more)

Canadian ENCs Added to UKHO Database

Canadian Electronic Navigational Charts (ENCs) which include the vital St Lawrence Seaway, a system of canals connecting the Great Lakes to the St Lawrence River and the Atlantic Ocean, have now been added for the first time to the UK Hydrographic Office's Admiralty database.   As new cells continue to pour into the service from all over the world, the Admiralty ENC and ECDIS services offer the most comprehensive offical coverage available from any provider in the world today. With electronic chart production at full tilt around the globe, the Canadian cells bring the number of high quality, official cells... (read more)

The ISO Standard for the ECS Database

ISO 19379
The Electronic Chart situation has developed in an unexpected way. When the first standards for chart systems were being written, the concentration was on those installations which would become the legal equivalent of a paper nautical chart. IMO produced a Performance Standard for ECDIS, and IHO prepared a companion standard for the ECDIS display; both were intended to define systems that would replace paper charts on board SOLAS vessels. IEC then produced a test standard to demonstrate compliance with these standards. All of these were completed in the late 1990s, and one would expect that by 2002 the world's shipping... (read more)

US Army IENCs and Hydrographic Database Technology

US Army IENCs and Hydrographic Database Technology In 2001, the US Army Corps of Engineers (USACE) began to produce Inland Electronic Navigational Charts (IENCs) for US waterways. A paper chart was made from IENC data by IIC, working with the Corps; now improved HPD technology has been used to further investigate this concept and its ramifications for multiple product consistency, currency and ease of production. An essential feature of any charting programme is continual maintenance and dissemination of consistent, updated and significant products. With recent advances in Hydrographic Product Database (HPD) technology it is now possible to link and merge... (read more)
