Satellite Positioning

Within the last twenty years Global Positioning System (GPS) receivers have revolutionised navigation. Integrated devices are capable of providing time, position, height, direction, heave and attitude to accuracies of a few nanoseconds time, 1cm position or 0.01 degree heading. All potentially displayed on a digital chart background with radar and auto-identification system overlays. In this first of two articles we look at current Satellite Positioning systems, how they work and how we can make them better. In a second article, to appear next month, we explore the future development of Satellite Positioning and the implications for navigation. How does Satellite... (read more)

Bering Sea ASV Force Multiplier

Arctic Hydrographic Survey Achieves Production Gains by Utilising ASV Technology
TerraSond, a hydrographic services company based in Palmer, Alaska (USA), used a C-Worker 5 (CW5) unmanned autonomous surface vessel (ASV) in conjunction with a 105’ (32m) research vessel from June through August 2016 on a major hydrographic survey in the Bering Sea region of Alaska. The ASV served as a force-multiplier, collecting multibeam and towed sidescan data alongside the larger vessel, which surveyed adjacent lines simultaneously. The 18’ (5.5m) ASV collected 2,275 nautical line miles (4,213km) – 44% of the project total – and achieved an industry first in terms of data production rates utilising ASV technology in the Arctic....

Market Prospects for AUVs

This article is based on the results of a new studyThe AUV Gamechanger Report 2008-2017published by Douglas-Westwood Ltd. This report aims to consider the prospects for this game-changing technology and value the future markets for AUV manufacturers to 2017.<P> Un-tethered Autonomous Under­water Vehicles (AUVs) have the potential to change the game in many areas of underwater oper­ations. Long an area of research, AUVs are beginning to show their abilities as cost-effect­ive tools in applications ranging from deep-water survey for the offshore oil and gas industry to military oper­ations. The growing need for many facets of ocean observation also offers great... (read more)

OpenSeaMap – the Free Nautical Chart

The biggest worldwide geodatabase, made by the crowd
Nautical charts are expensive, and in many countries data are not always up to date. OpenSeaMap is an alternative solution which is free for anybody to use worldwide. Following the example of Wikipedia, the data are collected by volunteers and are visible on the chart within just a few minutes. OpenSeaMap involves experienced mariners, programmers and thousands of data collectors, all of whom are working to produce a nautical chart with comprehensive, relevant and up-to-date data for water sports which is open to everyone and free of charge. OpenSeaMap – the free nautical chart – covers oceans and inland waterways... (read more)

Much More Than a Typical Hydrographic Office

Hydro International Interviews Capt Brian Connon, Director NGA Marine Safety Office
In October 2015, Capt Brian D. Connon assumed the role of director of the National Geospatial-Intelligence Agency’s Maritime Safety Office. The organisation is an important, although not always visible, link in the global maritime safety chain. Its work contributes to generic marine safety and, due to the nature of the data collected and analysed, its role is especially relevant for security, humanitarian assistance and disaster relief. In this interview with Hydro International, Capt Brian Connon lays out the role of hydrographic data and technologies in the NGA. Can you briefly outline the work of the NGA? The National Geospatial-Intelligence Agency (NGA) is the United States’ primary... (read more)

2D/3D Web-mapping

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)

Human Resources in Hydrography

Nowadays challenges are enforced by advanced technology
Certainly, all of us belonging to the hydrographic community have heard, read or even written, dozens and maybe hundreds of times about the importance of human resources when referring to the performance of reliable hydrographic surveys. That is a fact that upon which we have remarked and seen with some nostalgia, mainly because of the human tendency to consider that ‘Everything was better in the past…’ Nevertheless, whether we like it or not, things have somehow changed. The advancements of technology are marking tracks in the way our professionals are facing the challenge of extracting from nature the precise data... (read more)
