N2  - "U.S. Chart No. 1 presents two types of symbology used for marine navigation - the symbols used on paper nautical charts (and their digital raster image equivalents) and the corresponding symbols used to portray Electronic Navigational Chart (ENC) data on Electronic Chart Display and Information Systems (ECDIS) ... Navigation systems certified to meet the exacting performance standards established by the International Maritime Organization (IMO) are said to be ECDIS 'type approved'. The symbology used to display ENCs or other non-ENC nautical navigational data on non-ECDIS systems, such as geographic information systems, recreational GPS and other chart display systems can differ significantly from the symbology specified for ECDIS type approved systems. U.S. Chart no. 1 only shows the symbology used on ECDIS"--Page 5.
