An ENC exchange set is a platform-independent set of files suitable for use in electronic chart navigation systems.
An exchange set is composed of one catalogue file and at least one S-57 dataset file (.000 base file and/or .001, .002, etc., update files).
The catalogue file acts as a table of contents for the exchange set. Text (ASCII) and images (TIF) may be included in the exchange set if they are referenced by features in the S-57 file.
An exchange set may also contain a README file, which is an optional ASCII file of general information.
Exchange Set Editor lets you create exchange sets or edit existing sets.
