area, called the ENC database ; this shall only include ENC issued by Hydro-
graphic Offices.
Since the S57 (93/3) format is not suitable for data processing, the ECDIS shall
convert the ENC into a different format (usually binary and more compact than
S57(93/3)), called the SENC (System ENC) format. A special module of the EC-
DIS software, the SENC Compiler, performs the conversion from ENC to SENC
(see section 4.8 Installation (import)).
The resulting data is loaded into a separate storage area, the SENC Database,
from where it is accessed by the chart display and navigational functions of
ECDIS.
The ECDIS manufacturer may choose whatever format and database structure
for the SENC, provided that data is not downgraded in accuracy and/or contents
during the conversion from ENC to SENC.
1.1.2 Charting Capabilities for ENC
The provision of a timely, reliable worldwide uniform ENC data distribution ser-
vice is a major organizational challenge. The IHO developed the WEND (World
−
wide Electronic Navigational Chart Database) concept to meet these require-
ments. WEND consists of two components:
A charter describes the principles governing the cooperation between Hydro-
graphic Offices e.g.:
• By definition,the organization responsible for charting of an area is also
responsible for the ENC production.
• The relevant standards, especially S57 must be observed; and
•
The rules of a recognized work quality assurance system (e.g., ISO 9000)
should be applied to data production.
A conceptual schema describes a network of regional centers.
• Each so − called Regional Electronic Chart Coordinating Center (RENC)
takes over the responsibility in its area for the collation of ENCs and up
dates for the region;
• Through the exchange of the regional data sets and their updates between
all RENCs each RENC can offer an identical global data set for ECDIS;and
