Transas ECDIS check issues
Transas confirms that all latest versions of IHO standards have
been implemented in new
versions of Transas ECDIS (ref. above compliance table), there
may still be discrepancies in
displaying ENC Check dataset against the document
ECDIS_check-Instructions_for_Mariners.
Finding these discrepancies does not mean that your ECDIS does
not comply with the relevant
standards because they are caused by differences in
interpretation of chart display rules.
Details of the discrepancies with explanations are given
below.
1. ECDIS Check Instruction, Section 3 (the checks), Check 1,
paragraph 5 says The New object symbol (4) should appear as a
square and include the words Presentation Library 3.4 The text
Presentation Library 3.4 is not displayed on the screen, while
available by cursor pick report (ECDIS Info button). The text is
not shown because it has been encoded in this particular ENC test
data set in an unusual way, not normally used during normal ENC
production.
2. ECDIS Check Instruction, Section 3 (the checks), Check 3,
paragraph 3. Symbol 4 is not displayed with isolated danger symbol
in Standard Display mode. This is caused by different
interpretation of the IHO presentation library that contains
requirement to consider user setting Display isolated danger in
shallow water and change content of Standard display according to
this setting. The current version of Transas ECDIS has no such
setting because this contradicts with IMO/IEC requirement to
Standard display ECDIS shall present the Standard Display at any
time by a single operator action
If you have only found the two discrepancies listed above and
have ECDIS version equal or
newer than NS 3000 ECDIS-I v. 4.00.10 (MNS27) or NS 4000 ECDIS
MFD v. 2.00.xxx (Starting
from MNS28) we suggest you use the Info function for unknown
chart objects and always
switch on layer Isolated dangers in the tab Layers of Charts
functional panel.
To remove possible anomalies from Transas ECDIS and have more
standardized chart
presentation as expected by IHO experts, appropriate changes in
the software were
implemented and software patch for MFD ver. 2.00.320 (MNS32) was
release in October 2011.
After applying the latest patch to NS4000 ECDIS MFD, all chart
symbols in the ENC check
dataset are shown as expected by the IHO documentation.
