Whether navigating an oil tanker, cruise ship, fishing vessel, sailboat, or any craft, the mariner requires a suite of navigation charts that are consistent and easy to use. The public feedback we received to the National Charting Plan regarding the “sunset of paper” charts (p. 26) highlights two navigation products in particular, NOAA paper nautical charts and raster navigational chart (RNC).
NOAA’s Office of Coast Survey released a new electronic navigation chart (NOAA ENC®) of Haverhill, Massachusetts, and the Merrimack River (US5MA1AM). With this new chart, recreational boaters now can safely navigate the Merrimack River from the entrance at Newburyport all the way to Haverhill, just in time for boating season.
Knowing the locations of shipwrecks and other obstructions has always been important for safe navigation ‒ but mariners are not the only people who want to know about wrecks. They are also important for marine archeology, recreational diving, salvage operations, and fishing, among other interests. Now, Coast Survey has improved our Wrecks and Obstructions Database, giving everyone easy access to new records to explore.
Historically, Coast Survey has maintained two separate sources of information on wrecks. We recently combined the sources, bringing together information on nearly 20,000 wrecks and obstructions.
In November 2013, we introduced NOAA ENC Online – a continuous viewer for our electronic navigational charts. You can click on the web map and zoom to selected features or locations, to see the information contained in over a thousand electronic charts of NOAA-charted waters. Each zoom moves you through an ENC depiction that takes into account the ENC scale and other attributes that are encoded in the ENC, allowing features to become visible or invisible as you seamlessly zoom in and out of the data.
