New UKHO hydro app

Fri, 09 January 2015

The United Kingdom Hydrographic Office (UKHO) is inviting mariners around the globe to help further develop its Hydrographic Note (H-Note) service by using the new free H-Note app to submit hydrographic information.

UKHO’s H-Note app allows important navigational information to be recorded and shared faster and more easily than ever before helping to speed up warnings on dangers to navigation, changes in aids to navigation or required amends to charts or publications.

Hugh Phillips, head of product management, UKHO, said: “The ADMIRALTY H-Note App is a more efficient way for mariners to continue sharing any information with us that could be navigationally significant. Every mariner and every ship, whether sailing internationally or in local waters, has a part to play by serving as our eyes across the oceans."

The new app automatically transmist data to the UKHO at the touch of a button to include the user’s location co-ordinates via GPS and photos taken on the device.

All information received via the H-Note is used by the UKHO to either take immediate action to warn other mariners or to consider including the information in the next appropriate revision of a chart or publication.

The app can be downloaded for free by visiting the App Store on your device and searching for ‘H-Note’.

But non-smartphone users don’t fear. H-Note Forms can still be downloaded from the UKHO website or found in the Mariners’ Handbook. Once completed, they can still be submitted to the UKHO by email or fax.
