IENC Presentation Library 2.3

This side refers to the InlandECDIS Standard Edition 2.3, Section 3
It is outside of the scope of work of the Inland ENC Harmonization Group and will only be proposed for adoption for Europe and the Russian Federation.

S-57 data sets do not contain any information about how it is going to be presented. The chart presentation is generated online in the Inland ECDIS application. For that purpose, the Inland ECDIS application uses machine readable symbolization instructions for each feature which is drawn on the screen. For the presentation of ENCs the IHO S-52 standard is mandatory. The S-52 standard contains all rules which are necessary for the symbolization and presentation of ENCs on the screen.
Since the features, attributes and enumerations for ENCs were extended for Inland ENCs an extension of the S-52 standard is necessary as well in order to be able to display also the Inland specific features.

A clarification regarding the Conditional Symbology Instruction for notice marks (notmrk) under point 2.6 of the main document: it is not mentioned that the CS has also to contain the symbolization of "normal" single notice marks:

fnctnm1 > NOTMRK01

fnctnm2 > NOTMRK02

fnctnm3 > NOTMRK02

fnctnm4 > NOTMRK03

fnctnm5 > NOTMRK03

IEHG has decided to set up a portrayal register for Inland ENCs within the S-100 registry in the future.
