Electronic chart area

The ECDIS can use the following types of charts:
• S-57 (IHO)
• S-63 (IHO) (S-63 encrypted)
• ARCS (UKHO)
• CM-ENC (C-MAP by Jeppesen)
• CM-93/3 (C-MAP by Jeppesen)
The following information can also be displayed:

• Planned route
• EBL (Electronic Bearing Line) and VRM (Variable Range Marker)

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:
• S57ed3 ENC or CM-93 (vector format)
• ARCS (raster format)
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.
S57 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 dis-
played 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.
