Hi Coast Survey,

This week, Coast Survey is hosting a workshop at the University of New Hampshire Center for Coastal and Ocean Mapping (UNH-CCOM) with industry partners to discuss NOAA’s vision for Precision Navigation and build partnerships with the companies who currently disseminate our data. I would like to share a little more about NOAA’s Precision Navigation initiative and Coast Survey’s critical role in this project.

Currently, Coast Survey is collaborating with the U.S. Integrated Ocean Observing System, the Center for Operational Oceanographic Products and Services, the National Geodetic Survey, and the National Weather Service to integrate data streams that are important to the mariner into a single dissemination site, so end users have NOAA data at their fingertips to efficiently make decisions. Over the last six months, we’ve secured the domain,, and have started to build the backbone of the dissemination site. Building on our experience with nowCOAST, the dissemination site will be constructed and maintained in the cloud.

In addition to having a leadership role in the dissemination site development, Coast Survey’s new high-definition charts (or HD charts) will be a critical base for Precision Navigation. As mentioned earlier this year, many of the organizational changes we’ve seen within the Marine Chart Division will position them to support the production and distribution of products related to Precision Navigation.

As we continue to conduct this workshop, representatives from electronic chart system, portable pilot unit, and under keel clearance companies are providing feedback to help us improve the interoperability of the dissemination platform and identify potential testbeds for our Precision Navigation products.

I look forward to sharing more information about Precision Navigation as we move this project forward.
