A Colour Differentiation Test Diagram is provided to enable the Mariner to check the colour performance of his ECDIS screen, off-line, as described in S-52, section 5.2.5. It is illustrated in section 16.3 and fully described in sections 18.2 and 18.3.
In addition to the graphical form of the CSPs provided in this document they are also provided for use as a digital set of diagrams in Enterprise Architect form.
The digital part of the IHO ECDIS Presentation Library carries supplementary features intended to aid the manufacturer in implementing the IHO Colour & Symbol Specifications, and the Mariner in using them. These consist of:
An ECDIS Chart 1, as pseudo S-57 files, to help familiarise the Mariner with the colour and symbol coding used by ECDIS and to aid in picking the appropriate symbol for manual chart correction. (Note that the digital version of the ECDIS Chart 1 described here will be available in edition 4.0.0 of the Presentation Library, but may not be updated in the future. The ECDIS Chart 1 is also presented in section 16.2.)
A Colour Differentiation Test Diagram, as an S-57 file, to enable the Mariner to test whether his screen is still capable of differentiating the main colours used in ECDIS, and also to assist him in setting the brightness and contrast controls. (This digital version of the colour differentiation test diagram shall be supplied with the ECDIS as the diagrams are intended to test whether an aging ECDIS screen is still capable of showing colour differences clearly.)
