What was the primary reason for the creation of the reliable charts by the Hydrographic Office?

The primary reason for the creation of reliable charts by the Hydrographic Office was to facilitate navigation in unfamiliar waters. Accurate nautical charts are essential for safe maritime navigation, especially when vessels transit areas that are not well-known to the navigator. These charts provide critical information about water depths, coastline configurations, underwater hazards, and navigational aids, which are vital for avoiding accidents and ensuring safe passage.

While enhancing naval power and focusing on familiar waters are important considerations, the overarching goal of producing reliable charts is to support safe and efficient navigation where the risks associated with unknown territories are highest. Additionally, while academic studies of geography play a role in chart development, the practical application of these charts in navigation, particularly in unfamiliar areas, is what fundamentally drove their creation by hydrographic authorities.
