Croatian ENC production process - a new approach

Hydrographic Institute of the Republic of Croatia (HHI) has been producing Electronic Navigational Charts (ENC) since 2001. The process of ENC production proposed by the Italian company C-Map did not prove to conform to specific geographic characteristic of the Croatian part of the Adriatic Sea and HHI’s long tradition of chart production. It is the reason why there occurred the need for a redesign of the process of ENC production. This paper proposes new usage bands and compilation scales for each ENC usage band for the Croatian part of the Adriatic Sea. New classification of ENC cells is also proposed in the form of regular rectangular network, offering multiple advantages over the classification based on the HHI paper charts.
