An electronic nautical chart is a digital version of a nautical chart. NauticExpo offers both of the two main types, vector and raster.
The primary function of an electronic nautical chart is to represent a specific maritime area, along with its dangers and navigational aids: buoys, reefs, shallows, traffic lanes, cardinal directions, etc.
There are two types of electronic chart. Vector charts are generated from a hydrographic service data base. Content is standardized and it they used with an electronic chart display information system (ECDIS). Raster charts are scanned digital copies of paper charts published by a hydrographic service.
Vector charts offer much more data and functionality than raster charts. A chart will be chosen as a function of the area to be sailed.
