Hello Coast Survey,

I’m Thad, a cartographer with the Marine Chart Division (MCD). With NOAA’s 2019 Nautical Cartography Open House coming up, I want to highlight an indispensable part of every chart — geographic names. Once a name is on a chart it feels very permanent. But, what if that name changes? Or, someone wants to name an unnamed feature? I would like to take this opportunity to share the process required to establish or revise geographic names.

Anyone can be a proponent to name an unnamed feature or to change a named feature, but it takes a lot of work to get it recognized by the federal government and added to our charts. In most states the proponent would need to work with local government and state names authorities to gain the proper amount of local support.

Local support is a huge factor in getting a name recognized by the U.S. Board on Geographic Names (BGN). Established in 1890, the BGN is a federal body responsible for maintaining uniform geographic name usage throughout the federal government. Tara Wallace, branch chief of the Nautical Data Branch in MCD, and I represent the Office of Coast Survey as members of the BGN. Every month, we meet with representatives from other federal agencies and vote to approve or disapprove geographic name proposals. We utilize a set of naming rules and guidelines found in the Principles, Policies and Procedures manual.

Voting on names is not all we do. When the BGN receives a proposal it goes into a review process before it is voted on. If the name proposal falls within the boundaries of a NOAA chart, Tara and I are required to seek feedback on the proposal and offer an opinion on whether it should be approved or not. At this point, we ping our regional navigation managers or other NOAA personnel to get feedback from local stakeholders that may be interested in that feature. The feedback is sent to the staff at the BGN along with NOAA’s official opinion.

If the name is approved, it is entered into the Geographic Names Information System (GNIS) which is the authority for the place names on our charts, managed by U.S. Geological Survey.

Tara and I also represent NOAA at the Council of Geographic Names Authorities, an annual conference where federal board representatives interact with state and tribal naming authorities. We have also been part of the U.S. delegation to the United Nations for the Group of Experts on Geographical Names. Tara represents NOAA on the Advisory Committee on Undersea Features.

All of this activity ensures that our charts have the most up-to-date names and that NOAA has a voice in the naming process.
