NOAA’s Office of Coast Survey is reflecting on a successful and remarkable 2023! We completed many significant activities with meaningful impacts. As we look ahead to more progress in 2024, we are proud to share some highlights of the past year in our Coast Survey Year in Review ArcGIS StoryMap.Continue reading “A look back at 2023 and the Office of Coast Survey’s significant activities throughout the year”
The construction of the Erie Canal was one of 19th Century America’s most significant feats of engineering. Built between 1817 and 1825, the canal provided a water route from Albany to Buffalo, New York, nearly 363 miles to the west. The Canal connected the Hudson River with the Great Lakes via parts of the Mohawk River, through various land cuts and natural lakes. The New York State Public Works Department and the US War Department’s Corps of Engineers began geographically documenting the canal’s route with maps and nautical charts beginning in 1917. The Department of Commerce’s National Oceanic and Atmospheric Administration took ownership of the charts in the early 1970’s and has maintained and updated them for over 50 years. Currently, these charts are undergoing changes to usher them into the digital era of electronic navigational charts.

NOAA’s Precision Marine Navigation (PMN) program aims to seamlessly integrate high-resolution bathymetry and high accuracy positioning and shoreline data with the forecast data of water levels, currents, waves, and weather forecasts. This information can be easily accessed and integrated into maritime electronic charting systems and other decision support tools so mariners can plan their transits and make decisions while at sea and coming to and from port. A key component of this program is providing vessel pilots with detailed depth information to ensure safety of vessel transits and that critical under keel clearance safety margins are maintained. Electronic navigational charts, although accurate, typically do not provide the detail that pilots prefer.Continue reading “Vessel pilots transition to new chart format”
On February 14, 2023, NOAA’s Office of Coast Survey released NOAA Custom Chart version 2.0, a dynamic map application, which enables users to create their own paper and PDF nautical charts derived from the official NOAA electronic navigational chart (NOAA ENC®), NOAA’s premier nautical chart product.Continue reading “NOAA Custom Chart version 2.0 now available to the public“
NOAA maintains a suite of nearly 2000 electronic navigational charts (NOAA ENC®), as well as the ten volume United States Coast Pilot®. The seafloor and coastline are dynamic environments, which means that our products are constantly scrutinized for possible changes. Each year we make thousands of updates to ENCs, ensuring we are providing the most accurate products possible. The source data for most of these updates comes from NOAA or contractor surveys or from our federal partners, such as the U.S. Army Corps of Engineers and the U.S. Coast Guard. However, we also rely on many other data sources to help keep our ENCs up-to-date.Continue reading “Help keep nautical charts up to date through citizen science”
The Empowering Women in Hydrography project is a global effort led by the International Hydrographic Organization and Canada that seeks to initiate, organize, and track a series of activities and initiatives which will enable more women to participate equitably in the field of hydrography and to assume leadership roles within the hydrographic community. NOAA is contributing to the project via an ‘at-sea experience’ on NOAA hydrographic ships for three women each year over the four year lifespan of the project. After a global call for nominations, three women were selected to join NOAA ships for the 2022 survey season. Sub-Lieutenant Mercy Modupe Ogungbamila from the Nigerian Navy joined NOAA Ship Rainier from July 5 to 15, 2022 while surveying from Guam to Saipan.Continue reading “NOAA contributes to Empowering Women in Hydrography through at-sea experience, part 1”
Strategically placed around the country, NOAA’s navigation response teams―30-foot survey vessels with a three-person survey team―maintain emergency readiness while checking chart accuracy in changing ports and harbors. Navigation response teams work day-to-day in ports and harbors, collecting data to update the nation’s nautical charts. They measure depths, locate obstructions, report dangers to navigation, and update features for safe navigation. Whether there is a need to investigate wrecks, check for suspected shoals, conduct surveys for coastal management, or work with other federal agencies to support homeland security, Coast Survey’s navigation response teams have the expertise to get the job done safely and efficiently.Continue reading “Conducting survey operations with Coast Survey’s navigation response teams”
Nautical charts have always contained a great amount of information – even more so with electronic navigational charts. This information is constantly being updated, necessitating the need to keep your nautical chart suite as current as possible. The Office of Coast Survey’s online NOAA Custom Chart application enables users to create nautical charts directly from the latest official NOAA electronic navigational chart (NOAA ENC®) data. Users now have the ability to create their own nautical charts using individually set parameters, and then save this custom nautical chart as a file that can be viewed or printed.Continue reading “Have it your way – creating customized nautical charts using the latest data”
The new NOAA Chart Display Service (NCDS) renders NOAA electronic navigational chart (NOAA ENC®) data with “traditional paper chart” symbology in online and offline applications for which a basemap of nautical chart data is desired, including GIS, web-based, and mobile mapping applications. The new service uses symbols, labels, and color schemes familiar to those who have used NOAA paper nautical charts or the NOAA Custom Chart application. NCDS is available as Esri REST Map Service, OGC Web Map Service (WMS), and MBTiles formats.
