SevenCs - (W)ECDIS and Marine Geographical Information Systems

SevenCs stands for state-of-the-art digital cartography. Since 1992 we have produced digital charts according to standards of the International Hydrographic Organisation (IHO) and ECDIS software complying with the International Maritime Organisation (IMO) performance standards for electronic charts.

Years of experience in consultancy for public services and industry have earned SevenCs the reputation as being the expert for marine geographical information systems in the fields of (W)ECDIS, harbour and coastal surveillance, seafloor mapping, mission critical systems, naval combat systems, simulation and training.

SevenCs has a long record of cooperation with hydrographic offices around the world, and has leading manufacturers of commercial and military navigational equipment as major customers.

EC2007 ECDIS KERNEL – THE NUMBER ONE (W)ECDIS SOFTWARE DEVELOPER KIT (SDK)

EC2007 is an SDK that allows companies and organisations to build their own (W)ECDIS applications.

EC2007 SDK complies with:

• IMO performance standards for ECDIS
• IHO standards S-52/S-57/S-60/S-63
• IEC 61174
• STANAG 4564
• STANAG 7170

Several ECDIS applications using EC2007 have been type-approved by the Hydrographic Agency of Germany (BSH), Det Norske Veritas (DNV) and Qinetiq (UK).

The open concept of EC2007 is one of the big advantages for the users. It is grounded on international standards so no application based on EC2007 will force a user into a proprietary solution.

Supported data formats:

• S-57/S-63 vector data (ENCs, AMLs, InlandENCs, etc.)
• VPF vector data (DNCs, VMap, TOD, WVS+)
• ARCS raster data

EC2007 ECDIS kernel enables:

• Rotating vector charts for course-up display
• Printing chart images
• Querying on the chart and adding own objects
• Drawing on the chart and adding own objects
• Design routes and checking routes for dangers
• Monitoring and recording the voyage of a vessel
• Correcting charts both automatically and manually
• Zooming to arbitrary scales and omnidirectional panning
• Displaying multiple concurrent views

ENC TOOLS – EFFICIENT ELECTRONIC NAVIGATIONAL CHART ENC / AML PRODUCTION

The ENC tools are a collection of software to produce, maintain and disseminate Electronic Navigational Charts (ENC) in S-57 / AML format.

The solution is based on defined and internationally accepted standards. Therefore this approach does not constitute a proprietary solution. There is not just a facility to display AML symbols, but an additional entire software infrastructure consisting of tools for the production and administration of AML information. These tools are:

• ENC Designer data production software
• ENC Referencer - adds a geographic frame to raster images
• ENC Manager administrates ENCs / AMLs in an automatically generated directory structure
• ENC Interface a C++ API for reading proprietary spatial data formats and translating them into ENCs
• ENC Analyzer QA / QC software
• ENC Optimizer - significantly reduces the processing time of ENCs
• ENC Cartographer - produces INT1 compliant chart images from any set of ENCs

ORCA NAVY – ELECTRONIC CHART SYSTEM WITH AML-SYMBOLOGY

In cooperation with the German Navy, SevenCs has launched an AML enabled Electronic Chart System (ECS). The ORCA Navy uses the type approved SevenCs presentation library for ECDIS.

Specification supported by ORCA Navy:

• CLB (Contour Line Bathymetry)
• ESB (Environment Seabed and Beach)
• LBO (Large Bottom Object)
• MFF (Marine Foundation and Facilities)
• RAL (Routes, Areas and Limits)
• SBO (Small Bottom Objects)

Included in ORCA Navy is the SevenCs World Data Set. It displays 200m contours plus depth data with colours graded every 1,000m, tidal arrows from 0.5kt onwards, time zones, international borders, rivers and bodies of water, names and nations.
