What are official charts?
According to SOLAS V (see page 7) , charts issued by or on the authority of a Government ,authorized Hydrographic Office or other relevent government institutions are official and may be used to fulfill carriage requirements (provided they are kept uptodate).
All other nautical charts are by definition not official and are often referred to as unofficial or private charts.These charts are not accepted as the basis for navigation under the SOLAS Convention.
There are two kinds of official digital nautical charts commonly available ; Electronic Navigational Charts (ENC) and Raster Navigational Charts (RNC).
