Raster Navigational Charts (RNC)

Raster Navigational Charts (RNCs) are digital images of traditional paper nautical charts used for marine navigation. They display detailed representations of coastlines, depths, navigational aids, and hazards, helping mariners safely plan and execute voyages. RNCs are created by scanning paper charts to produce high-quality digital copies that can be viewed, stored, and updated electronically. They support electronic chart systems, providing mariners with accurate, reliable, and familiar visual information essential for safe navigation on the water.
