NOAA Hydrographic Community Prepares for Field Season

Once a year, the NOAA hydrographic community meets at the Field Procedures Workshop in the US to not only share information but have frank discussions about their challenges and the path forward in preparation for the upcoming hydrographic field season. “The Field Procedures Workshop is the single most important event of the year for NOAA’s hydrographic community,” said Rear Admiral Shep Smith, director of the Office of Coast Survey. “NOAA has become a global leader in hydrography because we use the full breadth of our community to continually refine our practices and adopt the best available technology and tools.“ Themes of...

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?

Cartography at the Source

New Products, New Ideas, Less Work
For two decades, CARIS’ hydrographic production database solution has enabled geospatial data to be managed in a data centric manner, while allowing various types of products to be created and updated from this one data centric source. A large user base of hydrographic offices worldwide has utilized this capability to produce and maintain a large percentage of the world’s paper charts and ENCs. Over time, the advantages of deriving products from one source has led to the introduction of more product types being produced by the system. Expanding from paper charts and digital chart products (such as ENCs and AMLs)... (read more)

Students and Researchers Get Access to OceanWise Marine Mapping via Digimap

OceanWise’ intelligent marine mapping data is now accessible to students in Further and Higher Education across the British Isles via Digimap, the online map and data delivery service provided by EDINA, based at the University of Edinburgh. EDINA works with data partners such as Ordnance Survey, British Geological Survey, Centre for Ecology and Hydrology, Getmapping and OceanWise, to offer access to a variety of data collections for the purpose and benefit of education and research. Digimap allows students and researchers to create or interrogate mapping online by selecting an appropriate base map, adding annotations and customising the content, using measurement... (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)

Where Do We Map Next?

A GIS Case Study from the Atlantic
Mapping the world’s oceans is a tremendous task that would benefit from a prioritisation strategy. In this article, an in-depth presentation of one such approach is given - a GIS-based analysis that identifies potential target areas for future mapping efforts in the North Atlantic Ocean. The authors state that more knowledge about the seafloor could be significantly accelerated if all bathymetric data were publically available. A Worldwide Data Gap Bathymetry underpins the safe, sustainable and cost-effective execution of almost every human activity that takes place at sea, yet most of the seafloor remains virtually unmapped, unobserved and unexplored. In fact,... (read more)

Mapping the Deep Ocean with Multiple AUVs

Ocean Infinity’s Seabed Exploration Project
Ocean Infinity’s seabed mapping campaign commenced in the summer of 2017. The Ocean Infinity team is made up of individuals from multiple disciplines, who have gained vast experience with deep-sea exploration operations in the past. Their combined knowledge and insight led to the idea to undertake deep-sea mapping operations using up to eight autonomous underwater vehicles (AUVs), paired with eight unmanned surface vessels (USVs). This novel concept is explained in more detail in this article. Human inquisition drives us to explore. This has led man to delve below the surface of the oceans. Our ability to understand the undersea world... (read more)

Vattenfall Procures OceanWise Raster Charts XL

Vattenfall, the Swedish energy group, has procured OceanWise Raster Charts XL (eXcluding Land) as a seamless Web Map Tile Service (WMTS) for Northern Europe. Based on standard nautical charts, and therefore with a familiar look and feel, Raster Charts XL are marine charts which have had all the land and other non-marine features removed. Meta-features such as scale bars, source data diagrams and title blocks have been removed meaning they no longer hide more useful information. Removing the land means Vattenfall can combine the WMTS with its own sources of land mapping data to give improved coverage in the coastal zone.... (read more)
