OceanGrafix, the exclusive provider of NOAA print-on-demand (POD) nautical charts for U.S. waters, announce that QR codes are now available on eight NOAA charts for the Tampa Bay, Fla., area. The National Oceanic and Atmospheric Administration (NOAA) added the QR codes in an effort to test their effectiveness in providing valuable and timely information to mariners. Quick Response Codes, or QR codes, are two-dimensional bar codes that can be scanned by a smart phone to direct users to digital content online. In this instance, boaters can scan the QR codes on select NOAA nautical charts to access real-time data sites for important information such as tides, currents, and marine weather.
