What is the file extension of the main chart file?

• A. ENC
• B. SENC
• C. 000
• D. DAT

Answer: (C)

The main chart file in the context of Electronic Chart Display and Information System (ECDIS) is stored with the file extension "ENC." ENC stands for "Electronic Navigational Chart," which is a standardized digital format for vector charts that are used in ECDIS. ENC files are essential because they contain data according to the International Hydrographic Organization (IHO) standards. This data is used for navigation and provides mariners with up-to-date and accurate chart information. The reliability of these charts is crucial for safe navigation at sea, as they offer information about depths, hazards, navigation aids, and other critical features. The other file extensions mentioned do not represent the main chart file. SENC (which stands for "System Electronic Navigational Chart") is a format used by ECDIS systems to represent ENCs in a format optimized for use in the device. The "000" and "DAT" file extensions do not correspond to standardized chart formats used in maritime navigation.
