Additionally, using the Legend in the Testing Supplement will help greatly in reading the chart.Īn aeronautical chart is the road map for a pilot flying under Visual Flight Rules (VFR).

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Follow Coast Survey on Twitter and check out the NOAA Coast Survey blog at offsite link for more in depth coverage of surveying and charting. Originally formed by President Thomas Jefferson in 1807, Coast Survey updates charts, surveys the coastal seafloor, responds to maritime emergencies, and searches for underwater obstructions that pose a danger to navigation. NOAA’s Office of Coast Survey is the nation’s nautical chartmaker. Last year, NOAA announced the privatization of chart printing and distribution, with NOAA-certified vendors providing improved paper “print-on-demand” charts that fulfill a vessel's requirement to carry a navigational chart published by the National Ocean Service in accordance with federal regulations. The changes are part of a systematic reconstruction of NOAA’s nautical products, anticipating mariner needs as navigation transitions to a new digital age. Printed charts provided by NOAA-certified Print-on-Demand (POD) providers fulfill a vessel's requirement to carry a navigational chart "published by the National Ocean Service" in accordance with federal regulations. Printing PDFs may alter the chart scale, color, or legibility that may impact suitability for navigation. The suite of RNCs will be upgraded starting April 3. Initial compatibility issues and discrepancies that were identified have been resolved. Coast Survey asked users how the changes affected chart appearances on mobile apps. This will improve image quality and legibility of the raster navigational charts ( NOAA RNC®) that are used in chart display systems. NOAA is also making available for free the NOAA ENC Online, a new web map viewing application that shows chart data previously only available to users who purchased specialized viewing systems.Īlso the digital charts’ image resolution will increase, from 254 dots per inch (DPI) to 400 DPI. Whether downloading one of the new PDF nautical charts, selecting a chart to order from a "print-on-demand" vendor, or finding an electronic chart, the interactive catalog presents a highly integrated suite of navigation products. To help boaters who aren’t sure which chart they need, NOAA has launched a new interactive chart locator that allows people to select a chart from a map of the U.S. To us, that represents more than two million opportunities to avoid an accident at sea.” “Within about 90 days of the product’s beta release, nearly 2.3 million charts were downloaded. “Up to date charts help boaters avoid groundings and other dangers to navigation, so our aim is to get charts into the hands of as many boaters as we can,” said Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey.
