Description

The official nationwide quilt raster marine charts as produced by the National Oceanic and Atmospheric Administration (NOAA). This layer covers the Great Lakes, Gulf of Mexico, and all U.S. coastlines, plus much of the Pacific Ocean, and the coastline of British Columbia, Canada. The charts portray water depths, dangers, landmarks, tides, navigational aids, and bottom characteristics, as well as regulatory information.

Warning

You should not use these charts for navigation. The chart tiles are official NOAA chart tiles, but Gaia GPS does not have a mechanism to keep them updated or to display relevant update metadata. Use of these products for any purpose is at your own risk.
