{{Main|Hydrography organizations}}

Hydrographic services in most countries are carried out by specialized [[hydrographic office]]s. The international coordination of hydrographic efforts lies with the [[International Hydrographic Organization]].

The [[United Kingdom Hydrographic Office]] is one of the oldest, supplying a wide range of charts covering the globe to other countries, allied military organizations and the public.

In the United States, the hydrographic charting function has been carried out since 1807 by the [[Office of Coast Survey]] of the [[National Oceanic and Atmospheric Administration]] within the [[U.S.&nbsp;Department of Commerce]] and the [[U.S. Army Corps of Engineers]].<ref> {{cite web|url=https://navigation.usace.army.mil/Survey/InlandCharts|archive-url=https://web.archive.org/web/20161028083119/http://navigation.usace.army.mil/Survey/InlandCharts|url-status=dead|archive-date=October 28, 2016|title=  About Inland Survey}}</ref><ref>{{cite web|url= http://www.nauticalcharts.noaa.gov/staff/aboutus.htm|title=  About Coast Survey}}</ref>
