What we do

The United Kingdom Hydrographic Office (UKHO) collects and supplies hydrographic and geospatial data for the Royal Navy and merchant shipping, to protect lives at sea. Working with other national hydrographic offices, we set and raise global standards of hydrography, cartography and navigation.

UKHO is an executive agency, sponsored by the Ministry of Defence.
