Navigate Hydrographic – the Nautical SmartChart

What is the core role of a hydrographer? To map the seafloor? Provide a precise position on the water? Some may believe it is to play with lots of expensive toys on boats, while colleagues are stuck in the office. While all those answers may be correct, I am asking about the core role of a hydrographer. I would suggest that it is collecting data to provide information that companies, clients and consultants rely on to make educated and accurate decisions. This is where our value as a professional service is demonstrated. However, here is another question - how do we present that information and, more to the point, could it be better?

Web GIS Improves Lidar Collection Response Time

The remarkable capabilities of airborne Lidar continue to improve, with scanners now able to emit more than a million pulses every second. Although it has never been easier to acquire high-quality laser data, storing and managing the huge volume of Lidar data collected can prove to be a challenge. Combined with associated metadata such as survey information, environmental conditions and flight lines, data management has now become a critical priority and focus. An initiative called the Lidar Management and Analytical Processing (LMAP) provides an automated workflow for uploading and storing Lidar and metadata into a Geographic Information System (GIS). Developed... (read more)

OGC Seeks Public Comment on MetOcean Profile and Extensions to WCS 2.1

The Open Geospatial Consortium (OGC) is seeking public comment on the MetOcean profile and extensions to WCS 2.1. Public comment on these documents was also held in 2018, but the documents have been renamed and the schemas updated, so a second round of comment is sought. The Meteorological and Oceanography (MetOcean) community works with massive datacubes of content organized in 4D space and time. Extracting valuable information from these datasets requires efficient query and delivery of the content perfectly suited to the user’s needs. The MetOcean community relies upon the OGC Web Coverage Service (WCS) to search and deliver such... (read more)

Streaming Cloud-based ENC Data for a Real-time ECS

A Cloud-based Infrastructure Specifically Designed for Marine Navigation
NaAVIC is a free and downloadable electronic voyage application that goes beyond the traditional Electronic Chart System (ECS) app whereby the data, including the ENC information, does not physically reside within the onboard computer. Instead, all the data is streamed from an up-to-date database that exists in the cloud. The on-demand data delivery model is not confined to conventional chart data. Whilst it includes ENC-derived data as a base layer, it is also designed to take additional data layers. These layers can be user-selected according to their needs to enhance the ECS capabilities. For example, the list can include raster... (read more)

Automated Depth Area Generation for Updating NOAA Nautical Charts

National Oceanic and Atmospheric Administration’s (NOAA’s) Marine Chart Division (MCD) is currently revising production efforts using an ‘ENC-first’ approach to provide seamless and tiled geographic coverage. Currently, ENC production workflows within MCD require cartographers to manually manipulate data in the Nautical Information System (NIS) to update navigation products. This MCD addressed this production bottleneck by developing a tool to derive depth area, contour and sounding vector data directly from gridded raster bathymetry surface data. Production of Electronic Navigational Charts (ENCs) Over the past decade, automation of data compilation procedures within NOAA’s Office of Coast Survey (OCS) and MCD (responsible for... (read more)

New EMODnet Bathymetry High-resolution Digital Terrain Model for the European Seas

An upgraded version of the EMODnet Bathymetry digital terrain model (DTM) for the European Seas has just been released. This bathymetry product now offers higher resolution, powerful 3D visualisation functionality and extended coverage of Europe’s seas. It is available free of charge for viewing, downloading and sharing by OGC web services from the EMODnet Bathymetry portal. The EMODnet DTM is a tool used for a whole range of applications in marine science, sustainable ocean governance and blue economy activities such as planning of pipeline trajectories, locations of offshore wind farms or planning of harbour extensions. In science, the DTM supports... (read more)

Seabed 2030: A Call to Action

Despite countless days of surveying at sea, we have still mapped less than 20 percent of the world’s oceans. It is time to get organised, according to Rear Adm Shepard M. Smith, director of NOAA’s Office of Coast Survey and the US national representative to the International Hydrographic Organization (IHO). With his paper titled 'Seabed 2030: A plan for high-resolution maps of the ocean by 2030', he will be opening the Hydrography, Geophysics & Geotechnics track of the conference at Oceanology International 2018 on 13 March at London’s ExCel. Read on for a preview of his presentation. Many people like me... (read more)

Fugro Leads Marine Industry in Support of Global 'Seabed 2030' Initiative

Fugro is leading the marine survey industry in support of NF-GEBCO Seabed 2030, a global initiative to produce a definitive, high-resolution bathymetric map of the entire world’s ocean floor by the year 2030. The initiative is being facilitated by the General Bathymetric Chart of the Oceans (GEBCO) project in partnership with The Nippon Foundation (NF) as a means to inform global policy, improve sustainable use and advance scientific research. Much less than 20 percent of the world’s oceans are mapped using modern survey techniques and Fugro recognises the importance of accurate seabed measurements (bathymetry) to numerous government, scientific and industry...

Research-driven Tools for Ocean Mappers

Fighting Repetitive, Manual and Error-Prone Routines the Smart Way
In a world where artificial intelligence is playing a key role in everyday life, it is disappointing when the everyday routines of an ocean mapper or cartographer involve solutions that are crudely manual, repetitive and error prone. Although the root causes of this situation might be debatable (e.g., constraints from abstruse formats, obscure algorithms, obsolete specifications, or a combination thereof), the advantages to the ocean mapping community of catching up with current-era technologies and moving towards smarter and more automated solutions are not. At first sight, many of the current issues are well-known generic problems, often with robust and widely... (read more)

Port of Rotterdam – Innovative Hydrography

ENC Production to the Max
The Port of Rotterdam is a leading global port and by far the largest seaport in Europe. The port is situated in the Rhine delta and with its direct connection to Europe’s largest industrial region, the Ruhr area, it is a key entry point to the European market. Understanding the depths throughout the 40km of the port’s waterways is critical to the day-to-day running of the port. Because the Netherlands Hydrographic Office only produces Electronic Navigation Charts (ENCs) for harbour usage, the port investigated the possibility of producing ‘Berthing’ ENCs containing high-density depth data to support decision-making within the port....
