Students of NOAA’s certification program in nautical cartography completed their final projects and presented them along with other Master of Professional Studies in GIS students during a poster symposium at the University of Maryland’s Department of Geographical Sciences. At the event, NOAA students explained their capstone projects and described how their research benefits nautical charting at NOAA. Project topics included:

  • Improving Shoreline Application to NOAA Electronic Navigational Charts, Megan Bartlet
  • An Automated Approach to Generate Nautical Vector Features from Raster Bathymetric Attributed Grid Data, Noel Dyer
  • Developing a Rasterization Procedure for Vector Chart Data, Christie Ence
  • NOAA Chart Discrepancies: A Temporal and Spatial Analysis for Navigation Response Teams, Lt. Cmdr. Matt Forney
  • Airborne Lidar Bathymetry’s Impact on NOAA Charts, Andres Garrido
  • Validating and Refining the Proposed Rescheming of NOAA Electronic Navigational Charts, Colby Harmon
  • High Resolution Bathymetry as an Alternative to Charting Controlling Depths in U.S. Army Corps of Engineers Channels, Craig Winn
  • Satellite Derived Bathymetry: An Alternative Analysis to Nautical Chart Updates, Aleah Worthem

NOAA clarifies National Charting Plan vision for production of NOAA paper charts and RNCs

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).

Collaborative effort to create new nautical chart returns recreational boaters to Haverhill, Massachusetts

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.

Haverhill is a historic New England town that has recently undergone an urban renewal with new federal, state, and private investment in the downtown and waterfront areas. Until now, this area of the river was not depicted at an appropriate scale on a nautical chart for recreational boaters to navigate safely. The community of Haverhill recognized the importance of recreational boaters to their local economy and led a grassroots effort to have a new chart created.

Coast Survey improves access to data on thousands of wrecks and obstructions

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.

Web-based map of wrecks
Coast Survey’s wrecks and obstructions database provides info on thousands of wrecks.

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.

Coast Survey unveils NOAA ENC Online enhancements

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.
