According to IHO standards, are ENC's allowed to overlap within the same usage band?

• A. Yes, freely
• B. No, overlapping is prohibited
• C. Yes, but only partially
• D. Only with proper permissions

Answer: (B)

According to the International Hydrographic Organization (IHO) standards, overlapping Electronic Navigational Charts (ENCs) within the same usage band is prohibited. The purpose of this regulation is to ensure clarity and consistency in navigational information provided to mariners. Overlapping charts can lead to confusion and misinterpretation of critical data, potentially compromising navigational safety. Ensuring that ENC boundaries do not overlap helps in providing a clear and precise presentation of navigation information. This principle is vital for maintaining the integrity and reliability of electronic chart systems, allowing mariners to make informed decisions without encountering conflicting information from overlapping charts.
