What you get: * RNC Charts — NOAA's Raster Nautical Charts, high-resolution and geo-referenced, downloaded once and available fully offline, off-grid, anywhere on the water. * RNC Catalog — browse and search NOAA's full raster chart catalog by region before you download. * NOAA Viewer — NOAA's Electronic Navigational Charts (ENC), vector-based and always current, viewed live. * Coast Pilot — NOAA Coast Pilot volumes, downloadable for offline reading, with sailing directions, hazards, and port information the charts alone don't cover. * Instrumentation — live GPS position, latitude/longitude, heading, and compass, right on your device. * Assistance — quick access to U.S. Coast Guard Navigation Center resources for boaters. Whether you're planning a coastal passage or need charts on hand with no connectivity, NOAA Nautical Maps keeps NOAA's own chart and publication data ready when you need it. -- NOAA Nautical Maps is an independent app and is not affiliated with, endorsed by, or sponsored by NOAA, the U.S. Coast Guard, or any government agency. It is a supplementary navigation aid — always carry an official, up-to-date means of navigation. About Electronic Navigational Charts (ENC) Electronic Navigational Charts are vector data sets supporting all types of marine navigation. Originally built for large commercial vessels using Electronic Chart Display and Information Systems (ECDIS), ENCs are now standard on simpler chart plotters used by recreational boaters too — providing real-time positioning and collision/grounding avoidance. NOAA ENCs comply with the International Hydrographic Organization's ENC Product Specification and cover more than 1,000 datasets across U.S. coastal waters and the Great Lakes. The U.S. Army Corps of Engineers produces the equivalent Inland ENC (IENC) product for many U.S. rivers. About NOAA Coast Pilot Coast Pilot volumes are NOAA's official supplement to nautical charts — narrative sailing directions covering channels, dangers, port facilities, and regulations that can't be shown on a chart alone. NOAA Nautical Maps lets you download volumes for the regions you need and keep them available offline.
