2.1.1 Electronic chart area
The ECDIS can use the following types of charts:
• S-57 (IHO)
• S-63 (IHO) (S-63 encrypted)
• ARCS (UKHO)
• C-MAP
The following information can also be displayed:
• Cursor (moved by trackball)
• Planned route
• EBL (Electronic Bearing Line) and VRM (Variable Range Marker)
• Radar image
• Own ship symbol with speed vector
• TT (Tracked Target, acquired from radar)
• AIS target
Electronic charts in ECDIS
The electronic navigational charts are displayed in the electronic chart area. There are
two kinds of electronic navigational charts available for use in the ECDIS:
• Vector format (C-MAP or ENC)
• Raster format (ARCS)
The ECDIS combines chart and navigational information. It should be noted that mod-
ern navigation systems (e.g., differential GPS) may offer more accurate positioning
than what was used to position some of the surveys from which the electronic naviga-
tional chart was derived.
ENC vector format
ECDIS is compatible with S57
Ed.3 ENC format charts. ENC
charts are converted to SENC
for use with ECDIS.
The details for the chart are
displayed in the electronic
chart area and these can be
modified. You can change the
chart scale with the ZOOM IN
and ZOOM OUT functions, and
the scale range is 1:1,000 -
1:70,000,000.
