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)

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)

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)

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)

ENC Sounding Checker

ENC Sounding Checker is a simple command line tool for MS Windows Operating Systems. It can be used to parse a single ENC (S-57 or SevenCs SENC) or multiple ENCs (if operated in batch mode) and check if there are soundings that are shallower than surrounding areas with depths attribution. ENC Sounding Checker does not modify the ENCs at all.   The affected features are reported and can be written to a log file. The log files can either: •be used as a manual reference for updating ENCs, or •imported in SevenCs ENC Designer software.   In February 2010 the... (read more)
