Bringing nautical charts of the Erie Canal into the digital era

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.

Vessel pilots transition to new chart format

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.

NOAA contributes to Empowering Women in Hydrography through at-sea experience, part 1

An image showing all woman officer hydrographers standing in front of NOAA Ship Rainier.

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.

Coast Survey launches NOAA Chart Display Service

This is a graphic showing an electronic navigational chart depicting the entrance to the Columbia River and Astoria, Oregon. Graphical information on the chart is rendered by the new NOAA Chart Display Service and shows traditional paper chart symbols.

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.

The nautical chart update process – build it and we will chart it

Nautical charts are updated with the most current information available through several processes and workflows within NOAA’s Office of Coast Survey. The large majority of these updates consist of revisions to water depth information. The bottom of a water body is changeable by nature, thus hydrographic surveys are constantly necessary to show contemporary depths in a given body of water. What doesn’t happen quite as often are changes to land along the coast, altering the way inlets, harbor entrances, and river mouths appear from a bird’s eye view. Unless there has been a catastrophic event, these changes in land are usually the result of human interaction.

New NOAA website provides marine navigation resources in a central location

Commercial vessels navigating in the Port of Los Angeles-Long Beach

A recently launched website from NOAA’s Precision Marine Navigation (PMN) program will improve the use and accessibility of NOAA’s marine navigation products and services. The website, Marine Navigation, includes links and short descriptions to NOAA’s various navigation resources, providing a one-stop shop that mariners can visit to get the data they need. Designed for shipping professionals and recreational boaters alike, the PMN program hopes the website will become a valuable tool to support all mariners in their navigation planning and decision making processes.

NOAA’s Precision Marine Navigation data service receives first major update

The Precision Marine Navigation (PMN) program has completed the first update of its prototype navigation data service – the PMN data processing and dissemination system and PMN Data Gateway viewer. The data processing and dissemination system provides surface current forecast guidance from NOAA’s forecast systems, in a prototype marine navigation data format. The viewer allows users to visualize the predictions and discover where they are. Both the system and the viewer were updated to include data from the recently upgraded Northern Gulf of Mexico Operational Forecast System (NGOFS2).

Nautical charts reflect alternate route along Gulf Intracoastal Waterway

Portion of Chandeleur Sound Gulf Intracoastal Waterway alternate route.

In anticipation of the temporary closure of the Gulf Intracoastal Waterway (GIWW)’s Inner Harbor Canal Lock, the Office of Coast Survey released three updated NOAA electronic navigational charts (NOAA ENC®) reflecting the Chandeleur Sound Alternate Route and the addition of 97 Aids to Navigation (ATON). The updated charts include US5LA24M, US4LA34M, and US4MS12M and can be viewed in NOAA’s ENC Viewer or downloaded from NOAA’s Chart Locator.

NOAA awards cooperative agreement to UNH/NOAA Joint Hydrographic Center

Students from the Center recovering a seafloor grab sampler.

NOAA’s Office of Coast Survey awarded a 5-year cooperative agreement to the University of New Hampshire for the continuation of the Joint Hydrographic Center. The Joint Hydrographic Center is a NOAA/University research and education partnership aimed at maintaining a world-leading center of excellence in hydrography and ocean mapping. The new award, which will begin in January 2021, will build on the work of the Center since its founding in 1999.
