Preconditions of use the ENC /ECDIS for ice navigation support

According to the last edition of SOLAS the use of ECDIS by vessels becomes obligatory

ECDIS provides an opportunity of use of the hydrometeorological information as additional information (transparent) layers of an electronic chart

It is easier for navigators to have all kind of information in one place (ECDIS) so that other inputs (Fax, pictures, telex, etc.) become not necessaryAARI

A question for IICWG TeamAARIWould the IICWG Team like to include as a standard format for geo-referenced images prj - files with WKT string ? (Ice code catalogue)
