4. ENCs have been introduced more than a decade ago. • Coverage has constantly improved. • ENCs are compiled for use in ECDIS in the first place. • Background bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

5. ENCs are not compiled for Navigation in confined waters. • Usually ENCs do not contain high density bathymetry. • Background bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

6. Type approved ECDIS must use ENCs. • ECS Systems (e.g. PPUs) also use ENC. • Navigation in confined waters is often done with ECS assistance. • Dedicated systems are available for high precision operations. • Background bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

7. To use an ECS for high precision navigation we need: • Most accurate positioning data. • Latest bathymetric survey data. • High density depth information. • ENCs do not meet these requirements. • Background bENC - PPUs & Electronic Charts, Southampton, 12 May 2011
