S57 Charts: Technical Features
TIME DEPENDENT WARNING
Each ENC object may have a time dependent behaviour. A specific object can be dangerous
during a limited period of time starting and ending at times specified by the data producers.
ACCURACY
The accuracy of calculations performed by ECDIS is independent of the characteristics of the
display and the calculation error is always less than the data accuracy of the most accurate
SENC. The resolution of the screen gives the limits of the accuracy of the displayed bearings
and distances.
