New IHO Guidelines for Hydrographic Geospatial Data

The IHO has published new guidelines for the development of product specifications for the creation of hydrographic geospatial data. Modern navigation systems and geospatial solutions use digital data from a variety of sources. In order to facilitate the integration of hydrographic data and applications, the IHO developed S-100, a hydrographic geospatial data standard that can support this array and that is fully aligned with international geospatial standards, in particular the ISO 19000 series. The aim of the new S-97 guidelines is to assist in the creation of harmonized product specifications utilizing S-100 for implementation within the e-Navigation ecosystem. This encompasses all product specifications... (read more)

Managing Bathymetric Data with RDBMS Technology

During the CHC 2010 Conference, Caris is organising workshop on bathymetric data management utilizing relational database management systems (RDBMS). This workshop is free for registrants at the CHC but requires pre-registration on the CHC website as places are limited. It will take place on Tuesday 22nd June 2010, from 1:30pm to 5:00pm. A need is becoming more and more apparent across the hydrographic sector for robust and efficient bathymetric data management utilizing relational database management systems (RDBMS).The solution must enable the storage and management of high-density bathymetric surfaces from Multibeam Sonar and LiDAR surveys alongside Singlebeam data and the sparse...

RIEGL Presents BathyCopter at Intergeo 2015

On the first day of Intergeo, RIEGL, Austria, showcased its latest development in UAS-based laser scanning: the RIEGL BathyCopter. This is a small-UAV-based surveying system capable of measuring through the water surface, ideally suited for generating profiles of rivers or water reservoirs. The robust and reliable platform design integrates the topo-bathymetric green laser depth-meter, an IMU/GNSS unit with antenna, a control unit and a digital camera. Additional news from the airborne side: RIEGL announced the introduction of the VQ-880-G Topo-Bathymetric Airborne Laser Scanning System now equipped with an optional infrared channel to supplement the data acquired by the green laser...

Hydrographic Event Management Tool

The USGS, USA, has released a web-based geospatial service known as the Hydrography Event Management (HEM) tool. It allows users to create, edit and display geospatial markers, called Events, that are referenced to the National Hydrography Dataset (NHD). Events can be customised by the user to represent almost any water-related feature. Some examples of Events include streamgages, scenic or impaired stretches of river, fish passage barriers, toxic spills, or put-ins/take-outs for boats. For this initial release, users can customise their own HEM Web edit tool using a sample application and the required web services.  The use of events is a... (read more)

Web GIS Improves Lidar Collection Response Time

The remarkable capabilities of airborne Lidar continue to improve, with scanners now able to emit more than a million pulses every second. Although it has never been easier to acquire high-quality laser data, storing and managing the huge volume of Lidar data collected can prove to be a challenge. Combined with associated metadata such as survey information, environmental conditions and flight lines, data management has now become a critical priority and focus. An initiative called the Lidar Management and Analytical Processing (LMAP) provides an automated workflow for uploading and storing Lidar and metadata into a Geographic Information System (GIS). Developed... (read more)

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?

Shom’s Historical Archives Made Available in Digital Form

In 2016, as part of the ARCHIPEL project (ARCHIves Patrimoniales En Ligne), Shom digitised 10,000 cartographic documents from all over the world and from its historical maritime and coastal archives. This unusual extract of 300 years of coastal and ocean history consists of approximately 3,300 marine charts, the oldest of which dates back to the late 18th century, and 6,700 hydrographic survey maps ranging from the beginning of the 19th century to the present day. These documents can be consulted and downloaded free of charge on data.shom.fr and diffusion.shom.fr in the section ARCHIVES MARITIMES. Available as images (JPEG2000 format), they... (read more)

Port of Melbourne Selects Bathymetrical Database

CARIS has recently completed a successful project for the provision of a bathymetrical database system for the Port of Melbourne Corporation (PoMC, Australia). PoMC conducts regular bathymetric surveys as part of its statutory obligation to provide safe and effective transit of vessels through the harbour. The project involved the integration of CARIS Bathy DataBASE and the Engineering Analysis Module into existing PoMC workflows. CARIS Bathy DataBASE is a management system for bathymetry data, with successful installations in over twenty countries. Bathymetry assets from a multitude of sources can be brought together, regardless of file size or data source and managed... (read more)

Support for Saudi Hydrographic Data Project

OceanWise, UK, has combined with Caris BV, The Netherlands, to support the General Commission for Survey (GCS), Kingdom of Saudi Arabia (KSA). The support is helping KSA to further develop its capability and capacity as it embarks on a programme to produce electronic navigation charts (ENCs) of its national waters, as well as supporting wider uses of hydrographic data, as part of the Kingdom’s National Spatial Data Infrastructure (NSDI). The work involved running two courses on hydrographic and oceanographic data management, database design and Marine SDI. The 5-day practitioner course involved theoretical and practical elements whilst the 2-day shorter briefing... (read more)
