What organization did the Admiralty establish in 1795 to collate reliable nautical charts?

The correct answer is the Hydrographic Office, which was established by the Admiralty in 1795 to compile and disseminate accurate nautical charts and hydrographic information. This organization played a critical role in ensuring safe navigation for naval and commercial vessels by providing detailed information about the marine environment, including depths, coastlines, and navigational hazards. The establishment of the Hydrographic Office marked a significant advancement in maritime safety, as it centralized the collection and updating of charts, making them more reliable for mariners.

The name reflects its purpose: focusing on hydrography, which is the science of measuring and describing the physical features of bodies of water. The Hydrographic Office also conducts surveys and engages in research to improve maritime navigation and safety, ensuring that sailors have access to the most current and accurate data available.
