ENC Watermarker

Data producers and distributors must protect their chart products against copyright violations. Until now there has been no method available to prove copyright violations with respect to S-57 charts. ENC data could be illegally duplicated, completely or partially. To combat copyright violations, SevenCs has developed ENC Watermarker. It individually marks data in the S-57/SENC cells by means of a hidden watermark. Thus, if unauthorized copies of ENCs appear on the market, the originator can identify his/her mark using ENC Watermarker to show that this is in fact a copy of his/her ENC. These marks are indelible and will survive practically... (read more)

Jeppesen Primar ENC Service

Jeppesen Marine has launched Jeppesen PRIMAR ENC Service, which effectively combines two services into a single offering that ensures mariners easy access to charts, from the Norwegian provider of marine electronic charts.   Jeppesen PRIMAR ENC Service will ensure that mariners are always navigating by an approved Electronic Navigation Chart (ENC) from PRIMAR or other hydrographic offices, when these are available. When an ENC is not available, the service will notify the navigator (during route planning or navigation) and run from the high-quality private vector data produced and distributed by Jeppesen Marine. Previously, these two sources of data were sold... (read more)

Automatic ENC Correction

The Chart Corrector has been created as a tool to assist the routine operations in the process of IHO S-57 ENC creation/correction. The authors considered all possible requirements of national cartographical agencies using dKart Inspector, ENC Alalyzer or Chart Controller for verifying in the process. The Chart Corrector interface has been designed with the end-user in mind and is surprisingly simple, but a remarkably efficiency is hidden behind this simplicity.   To correct a chart, the user makes three simple steps. Suppose you have an electronic chart and a validation check report from any of the well known verifiers you... (read more)

ENC Tools User Conference

SevenCs' second user conference will be on 1st November 2010 in Rostock, Germany, just before Hydro 2010. The one-day conference will feature guest speakers, hands-on seminars, and the opportunity to meet the team so questions can be asked to the company directly. The programme will focus on •Visualisation of 3D DTED and gridded bathymetry (BAG) with ENCs •Web Map Services for S-57/ARCS combined with other geospatial data•ENC encryption in accordance with IHO S-63•Automatic depth line generation for ENCs•ENCs for inland and port applications (read more)

SevenCs Innovates ENC Tools

SevenCs has launched updates for several products in its ENC Tools Suite. The update package includes fresh features, bug fixes and extensions due to new standards and specifications which are relevant to digital chart production. By integrating the latest version of the SevenCs ECDIS Kernel (EC2007 v.5.20) the ENC Tools Suite benefits from many Kernel features, such as supporting IHO’s Presentation Library 4.0. and performance. This version further assists the Inland navigation community. The product specifications for Inland ENCs (IENC 2.4) can be handled with the SevenCs renewed tool package: ENC Designer (production), S-57 Writer for FME (translation), SeeMyENC (visualisation), and...

Inland ENC Production

European Union
ECDIS has been standardised by the IHO in Special Publications No. 57 (S57) and No. 52 (S52) and is established in coastal and open sea areas. The S57 standard covers the data model of the chart, whereas S52 defines its presentation. These standards are well approved and thus changes and extensions must be handled carefully. Nevertheless, European hydrographic offices faced the need for adaptations since traffic signs and traffic regulations differ on inland waterways. As a consequence, European experts developed the Inland ECDIS standard as an amendment to the maritime standard. The problem has thus been solved by supplements, strictly... (read more)

ENC Life Cycle

From the quality perspective, an electronic navigational chart (ENC) as a product is more demanding than its paper predecessor. Quality control and quality assurance of an ENC is a complex matter. The task of ensuring ENC quality during practical chart production is much broader than the direct implementation of standards. Obviously, to meet the ENC challenge, different life-cycle steps must be taken.<P> Electronic navigational charts (ENCs) consist of digitised data conforming to the International Hydrographic Organization's (IHOs) S-57 ENC Product Specification that records all relevant charted features necessary for safe navigation, such as coastlines, bathymetry, buoys, lights, etc. An electronic...

First Slovenian ENC Released

UK-based IC-ENC has released the first Slovenian ENC, produced by the Geodetic Institute of Slovenia. This ENC is available through the IC-ENC VARs. Following the release of the first ENC, the Port of Koper (Band 5), Slovenia plans to continue with ENC production covering the wider area of Bay of Koper (Band 4), and eventually covering the whole territorial waters of the Republic of Slovenia with another ENC of a smaller scale. The Geodetic Institute of Slovenia started the production of ENCs a few years ago and completed a substantial amount of work. They were unable to validate it properly... (read more)

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)

NOAA’s ENC Training Programme

The key objective of NOAA’s ENC Training Programme is to educate Hydrographic Offices (HOs) on ENC workflow in the Office of Coast Survey’s Marine Chart Division (MCD). The workflow includes: acceptance of new sources, data compilation, validation and quality control, distribution and contracting. A nine-day training session was held in Silver Spring, Maryland, USA, from 1-9 March 2016. The attendees were cartographers from the Hydrographic Department at the Survey of Israel (SOI). By Dr Shachak Pe’eri, JHC/UNH and Sean Legeer, Office of Coast Survey, NOAA, USA The training began with a meeting between Limor Gur Arie, the head of the... (read more)
