U.S. Coastal Maps


Note – This service is being discontinued. We recommend visiting the "Raster Navigational Charts: NOAA RNC®."

The NOAA Raster Navigational Chart Website is the official NOAA site for navigational charts.  It provides free download of RNCs, which can be used to support marine GIS decisions. 

If you have any comments or concerns with OCS discontinuing U.S. Coastal Maps, please let us know by submitting an inquiry.

Coastal map Coastal Map Coastal Maps are digital data products for the coastal stewardship community.  Coastal maps are produced from NOS nautical charts for all near-shore geographic areas of the United States. 
The Coastal Map Data Layer for Geographic Information Systems (GIS) Project began with the purpose to create a digital georeferenced data layer to provide the coastal stewardship community and general public with non-proprietary nautical chart images for GIS derived products. The nautical chart contains information critical to navigational users, yet obstructs a clear view of the topographic and hydrographic data. The charts are therefore cleaned of all navigational aides and symbols, then prepared as TIFFs (Tagged) Image File Format) in local Mercator projection. Federal Geographic Data Committee (FGDC) compliant metadata is available online.
