9.3 Selecting the Objects to be Displayed in the Vector Chart
9.3.1 Overview
Symbols, areas, lines and labellings (collectively called objects in the following) are individually stored
electronically in a seperate data base and are displayed in the vector chart. Object classes (complete
sets of similar objects) are grouped into display groups; for example, the object class Restricted
Areas together with the object class Military Practice Areas and other similar object classes form the
display group Cautionary Areas. An appropriate and, at the same time, uncluttered display can be
achieved by selecting only those display groups which are required for the actual nautical task. Further-
more, for a number of objects (e.g. buoys), there is a choice between two symbol presentations. Irre-
spective of this, the number of text labels displayed can be influenced.
9.3.2 Categories of Display Groups
IMO has defined three categories for the selection of display groups that are to be shown:
- Display Base: Consists of the display groups which, as a minimum requirement, definitely have to
be displayed. They can not be influenced by the user and they are shown all the time. They are
normally not sufficient for safe navigation (only coast lines and obstacles).
- Display Standard: Contains the display groups which are normally necessary for voyage planning
and voyage monitoring (all standard display groups as shown below)
- Display All: Contains above two categories and all other display groups which are available in the
electronic chart
For the CHARTRADAR one further category is defined in the IEC 62388 test standard:
- Display Primary: The Primary Chart Information Set covers the display base plus fixed and
floating aids to navigation (buoys and beacons, details on following page).
SAM Electronics finally has added a category named Customized. In this category, all settings can be
made individually. See chapter A - 9.3.4 on page A-98 for details.
