The origins of contemporary hydrography can be traced to the late 1800s when international hydrographers and oceanographers recognized the necessity for uniform charting techniques and supervision of hydrographic operations. The creation of the International Hydrographic Bureau (IHB) in 1921 was a major achievement, signalling the beginning of worldwide collaboration in hydrography. Today, the presence of Hydrographic Services in almost every country with a coastline is a testament to the global recognition of the significance of hydrography in nautical issues, connecting us all insiders and outsiders alike, to a shared responsibility for our seas and oceans.
