NOAA’s Office of Coast Survey collaborated with U.S. and Canadian mariners, the Lake Carriers’ Association (LCA), and the Canadian Chamber of Marine Commerce (CMC) to update the Recommend Courses in Lake Erie and transfer them from paper charts to NOAA electronic navigational charts (NOAA ENC®). This bi-national effort involved compiling and updating information for Lake Erie’s 75 routes which span both U.S. and Canadian waters. These routes cover 20 NOAA and five Canadian ENCs.Continue reading “The Great Lakes are getting a digital upgrade”
Ever wonder what it’s like to be a member of the NOAA Coast Survey team? We use the Coast Survey spotlight blog series as a way to periodically share the experiences of Coast Survey employees as they discuss their work, background, and advice.

“The Coast Pilot is a supplement to the chart, and eventually the electronic navigational chart… This helps ensure that our knowledge of the subject is transferred to the navigator/mariners with little effort.”
This 130-page book describes the symbols, abbreviations, and terms used on paper NOAA nautical charts and for displaying NOAA electronic navigational chart (NOAA ENC®) data on Electronic Chart Display and Information Systems (ECDIS). The document also shows paper chart symbols used by the National Geospatial-Intelligence Agency and symbols specified by the International Hydrographic Organization.Continue reading “NOAA releases new edition of nautical chart symbol guide”
NOAA recently announced that all nine United States Coast Pilot® volumes now contain the U.S. Coast Guard International Regulations for the Prevention of Collisions at Sea (72 COLREGS) and the Inland Navigation Rules — commonly known as the “Rules of the Road.” The navigation rules are similar to rules on the highway as they present a consistent way to navigate safely and avoid collisions. Having the newly published Coast Pilot now fulfills the legal requirement for mariners to maintain a copy of these regulations on board.Continue reading “U.S. Coast Pilot® now contains Navigation Rules”
NOAA recently hosted its fourth NOAA Navigation Industry Day at the Annapolis Yacht Club adjacent to this year’s Annapolis Boat Show. This annual event welcomed maritime application and navigation system developers interested in learning about the latest freely-available navigation-related data streams, models, and products that NOAA offers.

This summer, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) and NOAA’s Office of Coast Survey together ran an interagency ocean mapping project across several large portions of the Cascadia Margin, offshore of California, Oregon, and Washington states.
This collaboration, conducted aboard the NOAA Ship Rainier, used hydrographic surveying equipment to collect swath bathymetry, backscatter intensity data, and full water column data within the project areas. The high-resolution geospatial data acquired will provide key baseline data for targeted USGS studies to improve hazard assessment and forecasting for marine geohazards offshore of northern California, Oregon, and Washington. NOAA will also use the data to update nautical charts for safe navigation in the region.

Coast Survey published its earliest version of the United States Coast Pilot in 1858, as Appendix No. 44 in Coast Survey’s Annual Report. The publication, organized into nine regional volumes, provides navigational information that can’t fit on nautical charts.
The U.S. Coast Pilot has gone through many iterations over the last 158 years. In the last century, we’ve added more information and added color to the historically black and white copy. More recently, we began posting book files on the web for easy download. We have now taken the next major step, enabled by interactive digital technology, to give boaters an enhanced and more accessible product. (Please note, the improved version is not mobile-friendly. You should use a tablet or larger screen.)
Breakthroughs in digital editing and publishing have allowed us to produce the U.S. Coast Pilot in a digital format called extensible markup language (XML). People won’t notice a difference from the original format — it looks the same as the paper copy — but the online version has some neat interactive features. To find them, go to the U.S. Coast Pilot, select your volume, and then click on a chapter in the left hand HTML column.
The U.S. Coast Pilot, the supplement to raster navigational charts (NOAA RNC®) and electronic navigational charts (NOAA ENC®), now provides geotagged reference points. A geotag is simply geographical location information assigned to a type of media. In this case, a geotag conveniently assists mariners with landmark positions and displays the associated nautical chart inset in the HTML version of Coast Pilot. Currently, 75 percent of the nine Coast Pilot volumes have been geotagged, with more points available each week to the mariner. Coast Pilot is updated and available for download weekly, and can easily be used on mobile devices such as smart phones and tablets. To access the geotags, select a Coast Pilot book and click the HTML hyperlink adjacent to each individual chapter of the book.
A terrific t-shirt is sold in tourist shops at some of our nation’s harbors. It has a “definition” of a nautical chart splayed across the front: “chärt, n: a nautical map that shows you what you just hit.” It’s funny… but unfortunately, too true too often.
Resolve to get your nautical chart this year and consult it before you hit something. Advancements in Coast Survey’s digital processes now allow us to review and update charts weekly, and get them to boaters’ fingertips faster − and with less expense − than was possible years ago.
Coast Survey’s mandate is to provide nautical products that help make maritime transportation safe. As we develop and improve navigational products for commercial mariners, we also look for opportunities to serve the recreational boating community. All of the products listed below are available as free downloads.
BookletCharts™ are nautical charts in booklet form, downloadable for printing from home computers. People like to put each page into a sheet protector, and keep the updated notebooks on their boats.
For the tons (and tons) of useful information that can’t be put on the nautical charts, check out the United States Coast Pilot®, nine volumes of supplemental information important to safe and enjoyable navigation.
