Web Visualisation Coastal Orthophotos
This paper describes the development of a web spatial image server used for sharing huge sets of georeferenced coastal orthophotos on the web via an easy visualisation interface. Traditional cartography was considered a highly sophisticated methodology for the production of high-quality maps, using the sales-business model of the non-internet economy and dedicated to specialists. The recent arrival on the scene of three internet leaders whose general mission is to map everything, and the release of their popular online earth browsers has had a huge impact in the geomatics arena. All are by now familiar with the success enjoyed by Google... (read more)

Oceanology International 2010 Preview (1)

Oceanology International, the world's premier event for the marine science and ocean technology community, will this year be held in London, UK, from 9th to 11th March. Over 6,600 attendees are expected to drop in on this event, visiting the world largest exhibition with over 500 suppliers, the associated biennial conference, or are attracted by the many vessels and networking opportunities. This preview aims to give a foretaste of this year's exhibition that is the largest ever held, with pavilions from Canada, France, Germany, Ireland, The Netherlands and individual exhibitors from nearly 30 countries. We invited exhibitors to introduce themselves... (read more)

Hydrospatial and the Marine Environment

The First Steps to Going Beyond Charting
Hydrographic offices (HOs) today exist in a world of accelerating technological change that is influencing human behaviour and creating new needs and ways of exploiting data to understand our world. HOs have traditionally been the producers of nautical information for safety of navigation. By the end of the 20th century, with the appearance of the IHO S-57 Standard, their main challenge was to evolve into a central database production system. Now, the critical challenge and opportunity is to evolve from there into a true geospatial agency, developing a hydrospatial information system (HIS) capable of providing products and services for multidimensional analysis...

Svitzer Ltd

With 13 years of acoustic inspections behind them (the last nine utilising the Focus 400 ROTV), Svitzer has, arguably, become a leader in ROTV pipeline inspections. With a highly skilled team of operators and data analysts at hand, Svitzer has the ability to carry out high resolution acoustic inspections and surveys with the Focus 400 ROTV anywhere in the world. Svitzer has been involved in the inspection of pipeline systems using side-scan sonar since 1989, when the company first carried out the inspection of Shell UK Expro’s southern North Sea pipeline system. Since 1993, the company has been operating Focus... (read more)

IENCs in Flanders

Inland Electronic Navigational Charts Produced by Flemish Hydrography
Safety of navigation on inland waterways is as important as in maritime waters. To guarantee this, Electronic Navigational Charts (ENCs) have now been produced for several years. As inland waterways have specific features and regulations different from the maritime area, the use of ENCs is not sufficient. International standards have been developed specifically for Inland ENCs, which contain chart information required for safe navigation on inland waterways and in mixed traffic zones. These navigational charts are extremely important as they cover not only the maritime navigation zone, but also the adjacent inland waterways in Flanders which have not been mapped... (read more)

GIS Analysis Tools in Submarine Cable Planning

While the advantages of Geographic Information Systems (GIS) for storing and displaying spatial data are widely recognised, the analytic capabilities are less well known outside the GIS community. Extensions to core GIS software make possible new information, insights and better understanding of spatial relationships. GIS analysis functions can identify locations that meet a set of criteria, reclassify data to a common class-scale, weight datasets and combine these to analyse suitability or adherence to a given set of rules. GIS provides the framework for solving complicated problems. The output can be displayed on a map, where relationships are apparent and solutions... (read more)

LBL Array for Hostile Topography

Using GIS to Find Transponder Sites Along Pipeline Routes
The unique seabed topography of oil & gas field 'Ormen Lange', in the North Sea near Norway makes it very difficult to design pipeline routes and associated structures in compliance with the strain and fatigue criteria governed by physical properties of construction materials, installation method and their interaction with the seabed. Despite substantial pre-lay intervention the pipelay corridor remained very narrow and positioning accuracies were required beyond the capabilities of vessel-borne (aided) sub-surface positioning systems. The installation tolerance described above, in combination with rugged terrain, presents a special challenge to the planning of sites for any acoustic positioning transponder which... (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)

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)

Aquatic Ecosystems from Space

EO water quality data over the internet
Space-borne Earth Observation (EO) can offer a low-cost source of information in spatially extended areas of interest. A number of services have come online in recent years to facilitate access to EO data on aquatic ecosystems, providing raw data or derived products from operational ocean-observing instruments such as MODIS onboard AQUA (NASA) or MERIS onboard Envisat (ESA). This article highlights the benefits and discusses the limitations of space-borne EO for monitoring spatially extended aquatic ecosystems. From a users' point-of-view, the decision to integrate EO data products into operational monitoring schemes has to be based on a thorough analysis of the... (read more)
