NOAA Simplifies Nautical Chart Error Reporting

NOAA has released ASSIST, a system for submitting questions and reporting nautical chart errors to NOAA's Office of Coast Survey. ASSIST has a mobile-friendly design and improved user interface that allows customers to access the system conveniently from any device. The tool replaces Coast Survey's Inquiry and Discrepancy Management System (IDMS), a database that collected nearly 20,000 comments, inquiries, and discrepancy reports since 2008. ASSIST offers new features including the ability to: Tag your submission on a NOAA chart, map, or satellite image Enter reports from a mobile device Comment or report an error using a single form   These...

Teledyne CARIS Unveils Enhanced Tools for Lidar Data and Automated Bathymetry Compilation

Teledyne CARIS has released of Bathy DataBASE 5.2, which introduces enhanced tools for validating and creating chart features from lidar surveys as well as new bathymetry compilation techniques. This version includes an updated workflow process found in BASE Editor designed for performing both quality control and feature set building from Lidar data. In the software, you can upload LAS/LAZ data to assess quality, adjust classification, and compare against other sources. It also allows you to identify relevant features in the point data and imagery, and easily model as S-57 features directly in the area-based cleaning tool, and build a DEM using... (read more)

FarSounder Joins NOAA as a Trusted Node

FarSounder is the most recent company to join the International Hydrographic Organization’s Crowd-Sourced Bathymetry (CSB) initiative by becoming a “trusted node” with the NOAA. This project enables mariners to voluntarily contribute seafloor depths measured from their vessels to NOAA’s data repository. The partnership can be seen as a logical step because FarSounder’s customers regularly travel to remote areas with poorly maintained nautical charts, using a FarSounder 3D-FLS for real-time navigation. Due to the development of FarSounder’s Local History Mapping (LHM), the latest feature of its SonaSoft software, users now have the ability to create a real-time chart of the seafloor... (read more)

WorldDEM Now Entirely Edited and Available via Streaming

Airbus Defence and Space has announced that the entire edited WorldDEM database, together with the already available WorldDEM4Ortho dataset, is now available via streaming.This online access to the WorldDEM and WorldDEM4Ortho of the entire Earth’s landmass facilitates a wide range of applications such as line-of-sight analysis, hydrological modelling, satellite imagery orthorectification and much more. Following the comprehensive global acquisition campaign and subsequent processing effort, WorldDEM data is now available for the entire world in an edited version. This dataset corresponds to a hydro-enforced Digital Surface Model with water surfaces of lakes and reservoirs set to a single elevation, rivers and... (read more)

Streaming Cloud-based ENC Data for a Real-time ECS

A Cloud-based Infrastructure Specifically Designed for Marine Navigation
NaAVIC is a free and downloadable electronic voyage application that goes beyond the traditional Electronic Chart System (ECS) app whereby the data, including the ENC information, does not physically reside within the onboard computer. Instead, all the data is streamed from an up-to-date database that exists in the cloud. The on-demand data delivery model is not confined to conventional chart data. Whilst it includes ENC-derived data as a base layer, it is also designed to take additional data layers. These layers can be user-selected according to their needs to enhance the ECS capabilities. For example, the list can include raster... (read more)

Automated Depth Area Generation for Updating NOAA Nautical Charts

NOAA’s Marine Chart Division (MCD) is currently revising production efforts using an ‘ENC-first’ approach to provide seamless and tiled geographic coverage. Currently, ENC production workflows within MCD require cartographers to manually manipulate data in the Nautical Information System (NIS) to update navigation products. This MCD addressed this production bottleneck by developing a tool to derive depth area, contour and sounding vector data directly from gridded raster bathymetry surface data. Production of Electronic Navigational Charts (ENCs) Over the past decade, automation of data compilation procedures within National Oceanic and Atmospheric Administration’s (NOAA’s) Office of Coast Survey (OCS) and MCD (responsible for...

Working Together to Map the Gaps

Earlier this year, NOAA announced the end of a testing phase for the development of a new crowdsourced bathymetry database. The public can now access the bathymetric observations and measurements from citizen science volunteers and crowdsourcing programmes through the International Hydrographic Organization (IHO) Data Centre for Digital Bathymetry (DCDB) Data Viewer. This operationalised database allows free access to millions of ocean-depth data points. The database also serves as a powerful source of information to improve navigation products and the general knowledge about seafloors, according to NOAA. Since 2014, the IHO has encouraged innovative ways to gather data and data-maximising initiatives... (read more)

New Challenges for Digital Chart Production

Advanced Technical Solutions Need to Be Implemented
Hydrographic Offices have realised that bathymetric data is not sufficiently represented in Electronic Navigational Charts (ENCs). A few aspects of this topic have already been touched upon in the presentation called ‘Innovative approach in automated contour generation’ that was presented at Hydro 2017. This article focuses on the challenges of high-density bathymetry chart production and introduces a new approach to cope with it. In the past, ECDIS users have repeatedly complained about the lack of bathymetric detail in Electronic Navigational Charts. The resolution of depth information is too coarse to adequately display the extent of areas that are safe for... (read more)

‘Unofficial Charts’ on the Horizon?

In the article entitled 'How Blockchain Will Have an Impact on Navigation', published in the March/April 2018 issue of Hydro International, Gert Büttgenbach explains how the new blockchain technology could be potentially beneficial for the production and distribution of nautical charts. One of the conclusions of the article indicates that the new technological environment calls for reconsidering the ’exclusive domain of national Hydrographic Offices’ (HOs) and suggests that the private sector could in future produce ‘unofficial charts’ that would be superior to ’official’ charts produced by the HOs. But these views reflect a misunderstanding of the situation, according to Gilles... (read more)

The Shape of the Future of ECDIS

1 July 2018 will be a historic date for chart navigation at sea, states Mathias Jonas in a recent article. On exactly this day ECDIS carriage requirement will be mandated for any new and existing vessel of relevant size on international voyages. This date, however, will not gain any particular reaction from those who are affected and this is due to the applicability and implicitness of technology. It is fair to say that this date marks symbolically that ship navigation has accomplished the principal shift from analogue paper charts to the era of digital chart navigation. I was one of those...
