Create S-57 Exchange Set

Сводка

Allows a mariner to view the Electronic Navigational Chart (ENC) datasets in an Electronic Chart Display and Information System (ECDIS) for shipboard navigation. An exchange set is a package of files that contains one catalog file and at least one S-57 dataset file (New Edition [EN] and Revised Edition [ER]). Once you have exported and published your S-57 data, you need to package the S-57 dataset files into a valid S-57 exchange set.

Использование

• Validate the S-57 dataset and clear it for publishing before creating the exchange set.

• This tool packages referenced external files into a default ENC_ROOT directory as follows:

  • ENC: (*.txt, *.jpg, and *.tif)
  • IENC: (*.txt, *.jpg, *.tif, and *.xml)
  • AML: (*.txt, *.tif, *.pdf, *.html, *.htm, *.jpg, *.avi, and *.mpg)

• This tool will automatically read all external files that are in the same folder as the S-57 product.

• The S-57 base dataset is required when creating an exchange set for updates.

• When using the Updates Only parameter, update datasets must be consecutive and can start with any number, for example, updates *.002 and *.004 must include *.003.
