What are the ENC Tools?

The ENC Tools are a collection of software products used to produce, maintain and distribute Electronic Navigational Charts (ENC) in S-57 format. The individual software tools can be purchased separately. They can be combined to build a perfect data-production environment matching the user’s requirements.

What kind of data can be produced with ENC Designer?

First of all, with ENC Designer data in IHO S-57 Edition 3.1, ENCs can be produced.
Furthermore, all latest editions of Inland ENCs, AML, Port ENCs and bathymetric ENCs are supported.

Can I use ENC Designer to digitize my paper charts?

Yes, you can. There are two possibilities:

  1. ENC Designer can be connected to a digitiser table. That way the paper chart can be directly digitised.
  2. A paper chart can be scanned and saved as an image file in common picture formats. You simply geo-reference this file with ENC Referencer and then load it into ENC Designer. That enables you to digitise directly on your computer monitor without the need for a digitiser table. Moreover, the digitising accuracy is much better than with a digitiser table.

Can I create S-57 master/slave relationships with ENC Tools?

Yes, ENC Designer enables you to easily connect objects, forming a master / slave relationship.
Our optimisation software, ENC Optimizer, offers a function that can carry out this process automatically.

Do you offer any software to convert digital data of different formats into S-57?

Yes, SevenCs now offers a plug-in for the famous FME® from Safe. Using FME and our S-57 Writer plug-in allows you to convert hundreds of different digital formats to S-57.

Can I test your software before I purchase it?

Of course we do offer time-limited evaluation licenses for our customers.  Please contact our sales department ([email protected]) if you are interested in testing our software.

How do I get updates for the software?

Within a valid software-support agreement you will automatically receive all available bug-fixes for your licenses. In addition you will be able to use our help-desk support via phone, fax and e-mail (Mon.-Fri.). A quotation for major updates will be available on request.
