symbolization and overscale indicator are used.
More precise cell exists under the ship's position.

TANDARDS
TheECDIS900 chart kernel comprises several hundred software components that are
compliant to the IMO Performance Standard for ECDIS, the IHO Standards S-52 V3.4 / S-57, IEC
61174 Ed.3. , IEC 672288 Ed.1..
ENC
It is impossible to alter the contents of the ENC. If an ENC cell is modified, the ECDIS900
detects the modification and rejects the cell during the installation procedure. Official ENC are
converted and stored with a proprietary format. The conversion maintains the precision of
the data and does not alter the accuracy of the data.
C
HART AREA AND RESOLUTION
The chart area size in ECDIS900 is bigger than 270 * 270 mm.
The pixel size of the screen is about 0.255 mm.
P
RESENTATION
The ECDIS900 chart information has been designed to be clearly visible for more than one
observer under different light conditions. The symbols are always drawn with the size
described in the presentation library V3.4. The character size of the text may be adjusted to be
clearly visible. See User Manual for more details.
All superimposed windows are temporary and can be moved and hidden at any time.
The 64 colours used for chart and MMI displays are compliant with S52 Publications.
