LINZ Hydrographic Infrastructure Project

Land Information New Zealand (LINZ) is the New Zealand Government's steward of authoritative hydrographic information for nautical charts and publications and provides the hydrographic infrastructure to support these services and products. This includes the policy, administration, people, technology and spatial information. LINZ inherited the infrastructure from the Royal New Zealand Navy in 1996. Digital and analogue data are stored in numerous datasets. However, the information is primarily in hard copy and there is no consistent metadata across these datasets. This system is not responding to the demands of the organisation and its clients. LINZ has sought an approach to standardising... (read more)

Call for Comments on Protocol Encoding

The Open Geospatial Consortium (OGC) Technical Committee's PUCK Standards Working Group was chartered to process the existing MBARI PUCK protocol as a candidate OGC standard compatible with the OGC Sensor Web Enablement (SWE) standards baseline. The standard proposal is available for comment. Most sensor networks require careful manual installation and configuration by technicians to assure that software components are properly associated with the physical instruments that they represent. Instrument driver software, configuration files, and "metadata" describing the instrument and its capabilities must be manually installed and associated with a physical instrument port. Sometimes these manual procedures must be performed under... (read more)

Plug-and-work Protocol Adopted

Open Geospatial Consortium has adopted the PUCK standard, which facilitates plug-and-play connections of electronic equipment. The standard is relatively simple, and several manufacturers have already implemented the protocol in their instruments' firmware. It augments existing instrument command sets without replacing them, so it can be implemented without abandoning existing firmware and software applications. The standard was originally developed by the Monterey Bay Aquarium Research Institute (MBARI) for oceanographic applications, but is useful in any sensor network containing RS232 or Ethernet-connected instruments.   Most sensor networks require careful manual installation and configuration by technicians to assure that software components are properly...

Esri Geoportal Extension to Become Open Source

The Geoportal Extension is to become a Free and Open Source solution from Esri. Despite code documentation and samples as included on the Geoportal Resource Center, implementers of the Geoportal Extension have continued asking for source code access to support integration with content management systems, map viewers, desktop etc. The Geoportal Extension will be released under one of the variants of the Creative Commons open source license and will include elements like:•Geoportal Web application•OGC CSW 2.0.2 catalog service with OGCCORE and ISO Application Profile support•INSPIRE compliant discovery service•Extensible FGDC, ISO, DC metadata support•Configurable search engine including spatial ranking algorithm•Federated searches...

Video Introducing EMODnet

The European Marine Data and Observation Network (EMODnet) consists of more than 100 organisations assembling marine data, products and metadata to make these fragmented resources more available to public and private users relying on quality-assured, standardised and harmonised marine data which are interoperable and free of restrictions on use. The organisation has created a video to illustrate its work. The video highlights the importance of sea and coastal observations and data for a range of applications and users, illustrates the process of collecting, processing, storing and making available marine data, and the need to embed this process in an interoperable...

EUROSEISMIC

In the framework of the EU-financed project EUROSEISMIC a central metadatabase for geophysical data derived from marine seismic surveys for the European Seas has been generated and developed. EUROSEISMIC established a metadatabase on the Internet for marine geophysical survey data held by the marine departments of the European geological surveys and their project partners. It consists of the following functionalities: Data-entry with on-line data import modules On-line data edit Data quality-control Data-retrieval by means of a map interface in combination with numerical extended search (allowing searches on mandatory and/or optional metadata fields) Data export GIS-based geographical interface for navigation and...

F I S : Re-survey Decision System

Using Fuzzy Inference Systems for Area Selection
Navigational safety and political-economic considerations make it essential for port administrations and hydrographic services to have a prioritised survey programme. Finding criteria that reflect the importance of re-survey over a given area is fundamental here. A better way must be found than traditional thematic classification. Fuzzy Inference Systems (FIS) have been used successfully to deal with such problems. This article presents its use for hydrographic re-survey selection. Establishing a re-survey priority programme is no ordinary task. Specialists must analyse many kinds of information that, due to their complexity, must be combined in criteria: first to find where re-survey is necessary... (read more)

Hydrographic Special Interest Group Sets Sail at Esri UC

More than 50 users from organisations ranging from the International Hydrographic Bureau (secretariat of the International Hydrographic Organization), NOAA Office of Coast Survey, Danish Geodata Agency (GST), and the Yangtze River Waterways Authority and several other users from the maritime world attended the Hydrographic Special Interest Group meeting during the Esri UC, held in July 2013. The meeting, called “Taking Hydrography Beyond the Horizons of Navigation” was held in the San Diego Convention Center, Room 31 B and moderated by Robert Ward, President of the IHB and Esri’s special guest. While the attendees had different interests and backgrounds, they all... (read more)

CARIS Demos Bathy DataBase 3.1

During Ocean Business, CARIS officially launched and demoed the new version of Bathy DataBase 3.1 which as a new feature supports Oracle 11g. Delegates interested to see the new development could witness the transfer and use of data and metadata all over the world.   Specialists could see how data can be zoomed in (and at thattime get more detailed like on Google maps which makes it possible to manage big sets of data without having to transfer data in a higher density than necessary, which is useful when handling the expanding volumes of sonar and Lidar data. The data... (read more)

International Workshop on the Advances in the Use of Historical Marine Climate Data (MARCDAT-IV)

The Fourth International Workshop on the Advances in the Use of Historical Marine Climate Data (MARCDAT-IV) will be held at the National Oceanography Centre, Southampton, UK between the 18th and 22nd July 2016. Please see MARCDAT-IV for more details. The workshop will be arranged around the following themes:     Data homogenization (benchmarking, bias adjustments, step change analysis, metadata)     Quantification and estimation of uncertainty     Data recovery and reprocessing (digitisation efforts and reprocessing of previously digitised data)     Reconstructing past climates     Integrating In-situ / satellite data sources     Consistency of the climate across domain (land, ocean, surface, subsurface, atmosphere) boundaries     The role of marine climate data in...
