Voyage Planning Using ECDIS (VPUE). ECDIS, which is now a mandatory shipborne navigational equipment for voyage planning and execution, can operate a variety of charts. The official charts are known as Electronic Navigational Charts (ENC) and Admiralty Raster Chart Service (ARCS). The charts are made and distributed by the hydrographic offices through a distribution network, and the vessel has to subscribe to a service provider. ECDIS uses digital charts (vectorized and raster charts) for navigational duties usually carried out with paper charts. The equipment must be type-approved and uses up-to-date official charts. 

For voyage planning, using an ECDIS is the same as with paper-based navigation. However, making a passage plan utilizing the full aspect of a type-specific ECDIS need some careful consideration!
