NOAA’s Office of Coast Survey released a new and improved map viewer featuring the status of NOAA electronic navigational charts (NOAA ENC®) as they undergo major improvements. The data is also available as a GIS map service. The public can now view ENC project status from the planning and creation stages all the way to completion, keeping them better informed when these enhanced navigational charts become available.Continue reading “Follow the status of electronic navigational chart improvements with NOAA’s new map viewer”

When I traveled around Europe as a young man, my first stop upon leaving the train station in a new city was at the tourist bureau kiosk for a paper city map. On a recent trip to Malaysia, I used my phone to find walking instructions to a street market across town. When I arrived, I described my route to my host, who said that the pedestrian bridge I had used only opened the week before.Continue reading “Nautical Charts: Marine Navigation Joins the Geospatial Revolution”

How to obtain NOAA ENC-based paper nautical charts after NOAA ends production of traditional paper charts
Recently, NOAA announced the start of a five-year process to end traditional paper nautical chart production. While NOAA is sunsetting its traditional nautical chart products, it is undertaking a major effort to improve the data consistency and provide larger scale coverage within its electronic navigational chart (NOAA ENC®) product suite. Over the next five years, NOAA will work to ease the transition to ENC-based products, such as providing access to paper chart products based on ENC data. The online NOAA Custom Chart prototype application enables users to create their own charts from the latest NOAA ENC data. Users may define the scale and paper size of custom-made nautical charts centered on a position of their choosing. Users may then download, view, and print the output. The application is an easy way to create a paper or digital backup for electronic chart systems.
This webcast will provide an overview of the sunsetting process and a live demonstration of the NOAA Custom Chart prototype, including a discussion of the improvements that are planned for the prototype.

NOAA’s Office of Coast Survey, the University of Southern Mississippi (USM), and Saildrone accomplished a key milestone in the research and testing of unmanned technology that can lead to enhanced seafloor mapping capabilities with the launch of the first Saildrone — a wind-driven and solar-powered unmanned surface vehicle (USV) — equipped with multibeam echo sounder technology in the Gulf of Mexico. NOAA anticipates the success of this mission and technical achievement will lead to mapping projects in the Arctic.Continue reading “Saildrone launched with seafloor mapping capabilities in the Gulf of Mexico shows promise for remote Arctic mapping”
Last week, NOAA’s Office of Coast Survey held its third annual Nautical Cartography Open House welcoming over 250 attendees from the U.S. and abroad. Government agencies, industry and academic partners, and members of the public attended. The open house featured posters, presentations, tours, and exhibits centered around four themes: Bathymetric Databases, Custom Charting, Innovative Cartography, and Precision Navigation. Dr. Shachak Pe’eri, organizer of the event and chief of the Cartographic Support Branch in the Marine Chart Division, welcomed attendees in the morning and John Nyberg, chief of the Marine Chart Division, gave the keynote speech.Continue reading “NOAA hosts 2019 Nautical Cartography Open House and Chart Adequacy Workshop”
NOAA’s Office of Coast Survey is the nation’s nautical chartmaker, and maintains a suite of more than a thousand nautical charts. Coast Survey is responsible for charting U.S. waters and Great Lakes covering 3.4 million square nautical miles (SNM) of water and 95,000 miles of coastline.
NOAA’s hydrographic survey ships along with hydrographic contractor vessels, recently kicked off the 2019 hydrographic survey season. These surveys not only update the suite of nautical charts, but also help to maintain the safety of maritime commerce, recreational boaters, natural ecosystems, and much more. Operations are scheduled for maritime priority areas around the country and are outlined in Coast Survey’s “living” story map. Here is a list of where they are headed this year:Continue reading “NOAA releases 2019 hydrographic survey plans”
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’s Office of Coast Survey maintains a suite of over 1,000 NOAA electronic navigational charts (ENC) and paper nautical charts, and like many other chart producing nations, maintains an ENC focused production process called “ENC-first.” That is, ENCs are the “first” or primary nautical product, and new data is compiled onto ENCs before all other products.Continue reading “NOAA encourages all mariners to use NOAA ENC® for latest updates and other advantages”
NOAA recently released 13 new large-scale electronic navigational charts (NOAA ENC®) of Etolin Strait, Alaska. These charts provide a nearly twenty-fold increase in scale over the previous ENC coverage. New Etolin Strait hydrographic surveys and the resulting ENCs served as a pilot project for the overall rescheming of the entire NOAA ENC suite with a regular, gridded layout for ENC charts, as outlined in NOAA’s National Charting Plan. No corresponding NOAA raster nautical chart products in Etolin Strait will be produced. This is in keeping with Coast Survey’s “ENC-only” production concept, which generally maintains the current raster chart product coverage, but only creates new larger scale coverage in the ENC product line.
NOAA’s Office of Coast Survey recently announced plans to change the U.S. Army Corps of Engineers (USACE) maintained channel depth values on raster nautical chart products, which include paper nautical charts and the corresponding digital raster navigational charts (NOAA RNC®). Minimum depths (also called controlling depths) are collected during periodic USACE sonar surveys of channels. In the past, these depths were provided on raster charts, but controlling depths will now be replaced with the original channel design dredging depths used by the USACE (called project depths). Standardizing depth presentation on these products will improve data consistency and overall safety. Implementation begins in early 2019.Continue reading “NOAA announces change in channel depths on raster nautical chart products”
