Web Access to NOAA Hydro Survey Plans

The NOAA Coast Survey is posting its three-year survey plans and making them publicly available at the Planned NOAA Hydrographic Survey Areas (2015-2017) in ArcGIS Online. In addition to seeing the outlines of planned survey areas for the next three years, users can obtain additional metadata (project name, calendar year, and area in square nautical miles) for each survey by clicking on the outlines. With over 3.4 million square nautical miles of U.S. waters to chart, NOAA’s Office of Coast Survey is constantly evaluating long-term hydrographic survey priorities. The Hydrographic Survey Division is Coast Survey’s primary data acquisition arm. They... (read more)

Safe Software Extends Raster ETL Capabilities

Safe Software has introduced support for Bathymetric Attributed Grid (BAG), enhancing their raster ETL offerings in the marketplace. FME now enables organisations to translate and convert data between BAG, a widely recognized raster-based bathymetric data exchange format, and over 225 other formats supported by FME. A non-proprietary raster-based bathymetric data exchange format, BAG was created to facilitate the processing and storage of large volume multi-beam sonar data and is commonly used by the hydrographic community.     New support in FME for the BAG format includes translation to and from the format, as well as data conversion capabilities. Users can... (read more)

Source Data Management

The potential for hydrographic information in the holdings of today’s Hydrographic Offices (HOs) extends far beyond its classical use: the production of charts and nautical publications to ensure safety of navigation. Historically, HOs have collected far more data and information than has ever been published in charts and nautical publications. Since the establishment of the first Hydrographic Offices more than three centuries ago, a sensible archiving system has been sufficient for the management of source data. However, the move into the digital era and extension of the mission and objectives of HOs are changing the requirements for and possibilities of... (read more)

Marine SDI

Introducing Spatial Data Infrastructures
Global warming, climate change, rising sea levels and increased commercial exploitation of the seabed and sea space are important global indicators of a changing world environment. A crucial role is played by hydrographic and oceanographic spatial data in supporting response. Accurate and timely base reference information minimally comprises seabed topography and characterisation to which temporal information such as wave, tide and current can be referenced. In order to provide a complete picture, information held by HOs, National Mapping Agencies (NMAs), geologists, biologists and oceanographers can be brought together to provide solutions through enabling frameworks known as Spatial Data Infrastructures (SDIs)....

Hands-off ENC Production

Redefining High-density ENC Production
Imagine piloting a 398m container ship into port TODAY using an ENC updated with survey data collected YESTERDAY. Isn’t this order of turnaround time the ultimate dream of any ENC production agency? Modern echo sounders are able to provide a staggering amount of sounding data. Managing, and storing, the ever increasing volume of survey data is becoming a hot item on the agenda of many ENC producing agencies, including port and river authorities who have taken on the responsibility of creating and maintaining their own ENCs. Processing this data into high-quality, high-density ENCs requires a powerful, flexible and easy-to-use ENC... (read more)

Geospatial Data Updating at Sea

The Network Centric Mapping Database (NCMD) Web Service Design
A growing problem exists with forward-deployed electronic chart display and information systems (ECDIS) in obtaining and updating geospatial data(electronic nautical charts). This problem is commonly referred to as distributing geospatial data over the “last tactical mile”. As a solution to this problem, the US Navy has developed software called “Network Centric Mapping Database (NCMD)”. NCMD is a software capability that automates data distribution, with a focus on geospatial data (vector map data, raster map data or imagery). NCMD has been developed as a web service and multi-tiered software application that allows deployed C4ISR system to autonomously obtain and update geospatial... (read more)

News A combined AHS Annual General Meeting and General Meeting of the East Australia Region was held on Tuesday 27th September 2005 in The Wardroom, HMAS Kuttabul, Sydney. We had the pleasure of reuniting with our more distant members from New Zealand and Western Australia, namely Kevin Smith, chairman of the NZR, AHS honorary secretary, Mal Jones, and WAR chairman, Bill Russell Cargill. The incumbent president, Paul Hornsby, honorary secretary, Mal Jones and honorary treasurer Ron Furness were re-elected as the AHS executive officers. The AHS had never before declared for Society purposes its definition of hydrography. But a proposal... (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)

MSDI Working Group Hosted in UK for First Time

UK-based OceanWise and the United Kingdom Hydrographic Office (UKHO) hosted an Open Forum on Marine Spatial Data Infrastructure (MSDI) followed by the 6th International Hydrographic Organisation’s MSDI Working Group (IHO MSDIWG) meeting at the Holiday Inn Express Hotel, Terminal 5 near Heathrow Airport, London, from 3-6 March. The theme of the Open Forum was ‘Building a Maritime Spatial Data Infrastructure – are the principles at odds with strategies for delivery?’ This annual event, held in the UK for the first time, brought together practitioners and decision-makers from all over the world, including Canada and Japan, all with a common interest...

Managing and Monitoring Dynamic Environments

TCarta Marine has made dynamic environments easier to monitor and manage with the introduction of its multi-scale Shoreline products. Offered in GIS-ready vector format, the Shoreline datasets are derived from satellite imagery and accurately delineate mean sea level for the land-water interface in coastal areas around the world. TCarta Marine is creating the Vector Shoreline Products at global, national and local scales for mapping applications like environmental protection, coastal infrastructure development and flood insurance rate calculations. Many of the Vector Shoreline Products are available off-the-shelf, while others are custom derived from archived or newly collected satellite imagery. Global and Regional... (read more)
