ENC Designer Enterprise…

…is the core of SevenCs production suite.

The Enterprise package contains:

ENC Designer

ENC Manager

ENC Referencer

NTX Converter

ENC Designer

Creation and maintenance of S-57 data (ENC, IENC and AML)

Based on SevenCs ECDIS Kernel used in many type-approved ECDIS systems

Read-only mode for visual data validation

Powerful graphical tools and functions to create, edit and modify objects

User-friendly object and attribute queries

Plot function for visual data verification

Unparalleled method of uniquely assigned record identifiers (affords direct access to a potential GIS database)

ENC Designer

ENC Designer

Work-flow management environment for the maintenance of S-57 data

Easy data handling organized in a hierarchical database-similar structure grouped by producing agencies, navigational purposes and editions

Production of new ENCs, IENCs, AMLs, updates, new editions and S-57 Exchange Sets

Data production directly out of ENC Manager in SevenCs ENC Designer

Data quality assurance directly out of ENC Manager with SevenCs ENC Analyzer

ENCs are assigned to different working stages (edit, update or validate)

ENC Manager- incl. in ENC Designer Enterprise

ENC Manager- incl. in ENC Designer Enterprise

Easy to handle tool that allows to georeference raster data

With this information a geographic position can be calculated for every point of the image

Allowed image formats:

• BMP (Windows Bitmap)

• PNG (Portable Network Graphics)

• TIF(F) (Tagged Image File Format)

The referenced raster file can be loaded into ENC Designer to digitize the chart

ENC Referencer- incl. in ENC Designer Enterprise

ENC Referencer- incl. in ENC Designer Enterprise

C++ class library for interfacing between S-57 ENC data and other formats or databases.

Enables programmers to…

… write interface applications

… import or export data from or to database programs

… write converters to or from any related data format

Costfree tool can be downloaded from www.sevencs.com

ENC Interface

Powerful tool to enhance the data quality of ENCs

Minimizes memory requirements, maximizes display performance

Automatic correction of digitizing errors, e.g. duplicate geometry, non significant characters etc.

Startable directly out of SevenCs ENC Designer or as stand-alone tool

Logfile allows to step through the single optimizations in SevenCs ENC Designer

Filter function allows to apply single optimization functions to particular objects

ENC Optimizer

ENC Optimizer

Powerful validation tool for S-57 ENC data sets

Performs over 600 checks according to S-58 IHO Recommended ENC Validation Checks

Can be run as stand-alone tool or directly started out of SevenCs ENC Designer and ENC Manager

Checking engine provided by HSA Systems, Australia

Logfile allows to step through and correct the single warnings and errors directly in SevenCs ENC Designer

This software is a joint project between HSA Systems Pty Ltd, Australia and SevenCs GmbH.

ENC Analyzer

ENC Analyzer

FME S-57 Writer Plug-in (Converter)

Plug-in for FME of Safe Software Inc., Vancouver

FME - Integrated collection of Spatial ETL (Extract,

Transform, and Load) tools for data transformation and

data translation.

Supported S-57 products are

ENC (Electronic Navigational Chart)

IENC (Inland ENC)

AML (Additional Military Layers)

Derive INT1/INT2 paper chart from one or more S-57 ENC cells

Define multiple panels for paper chart

Creation of Zones of Confidence (ZOC) diagrams using S-57 quality objects

Support of INT2 borders and graticules

Generation of marginalia and text

This software is a joint project between HSA Systems Pty Ltd, Australia and SevenCs GmbH.

Spatial Vector Graphics (SVG) generated file for cartographic editing

Tidal Stream and Compass Rose paper symbols derived from S-57 objects

ENC Cartographer

ENC Cartographer

Makes sure your data is always recognisable yours

The original chart is not touched! A replacement data set is generated containing the digital watermark

Watermarking of individual cells and exchange sets

Checking data sets against the user determined watermarks

Protects your S-57 ENC data against data piracy

Any suspicious cell can be put through a correlation test against the user created watermark profiles stored in a database

Tabulated and graphic display of the results of the watermark check

ENC Watermarker

ENC Watermarker

ENC Dispatcher – combines S-57 data sets into ENC Units which can be named e.g. after a chart area for improved marketing

ENC Master – is the front end to ENC Server and creates S-63 permits and Chart Access Keys for the ENC Units.

ENC Server – handles ENC copyprotecting / encrypting and key management in an integral environment

After the production process the distribution of ENCs is of high interest for the producer.

SevenCs developed its own set of S-63 encryption and permit generation tools:
