In ECDIS, in order to reproduce the IHO colours for ECDIS, a colour calibration at the monitor must be performed to transform the CIE-specified colours for ECDIS into the colour coordinate system of the screen. Calibration will ensure correct colour transfer at the time a DISPLAY leaves the manufacturer’s plant.
6222
compilation scale
In ECDIS, the SCALE at which the DATA was compiled.
6223
cursor-pick
In ECDIS, the process of querying a point-symbol, line or area for further information from the data base which is not represented by the SY... more
In ECDIS, the process of querying a point-symbol, line or area for further information from the data base which is not represented by the SYMBOL.
6224
data quality indicator

In ECDIS, an indication of reliability and ACCURACY of surveys of a particular area provided through relevant ATTRIBUTE of the quality of data META OBJECT in the IHO TRANSFER STANDARD.
6225
display priority

In ECDIS, detailed rules to decide which line or point SYMBOL is to be shown when two OBJECTS overlap. Priority 2 overwrites 1. Display priority is given in the LOOKUP TABLE.
6226
drawing sequence
In ECDIS, the implementation of DISPLAY PRIORITY.
6227
Electronic Chart System (ECS)

Navigation information system that electronically displays vessel position and relevant nautical chart data and information from the ECS database on a display screen, but does not meet all IMO requirements for ECDIS, and does not satisfy SOLAS Chapter V requirement to carry a navigational chart.
6228
ENC product specification
In ECDIS, the IHO Standard which specifies the content, structure and other mandatory aspects of an ENC.
6229
encoding conventions
In ECDIS, a set of rules to be followed when encoding DATA for a particular purpose.
6230
face
In ECDIS, a two dimensional SPATIAL OBJECT. A face is a continuous area defined by a loop of one or more EDGES which bound it. A face may co... more
In ECDIS, a two dimensional SPATIAL OBJECT. A face is a continuous area defined by a loop of one or more EDGES which bound it. A face may contain interior holes, defined by closing loops of EDGES. These interior boundaries must be within the outer boundary. No boundary may cross itself or touch itself other than at the beginning/end NODE. None of the boundaries may touch or cross any other boundary. Faces are defined only in the FULL TOPOLOGY data structure.
6231

In ECDIS, a feature record is the implemented term used in the S-57 data structure for a FEATURE OBJECT (i.e. a feature object as defined in... more
In ECDIS, a feature record is the implemented term used in the S-57 data structure for a FEATURE OBJECT (i.e. a feature object as defined in the DATA MODEL is encoded as a feature record in the DATA STRUCTURE). There are four types of feature records: GEO, META, COLLECTION, and CARTOGRAPHIC.
6232
fully automatic updating
In ECDIS, the application of corrections to ENC DATA in the SENC in a fully integrated state, without human intervention.
6233
geometric primitive
In ECDIS, one of the three basic geometric units of representation: POINT, LINE, and AREA.
6234
HO-information
In ECDIS, the information content of the SENC originated by hydrographic offices. It consists of the ENC content and UPDATES to it.
6235
isolated node
In ECDIS, an isolated zero-dimensional SPATIAL OBJECT that represents the geometric location of a point FEATURE.
6236
line
In ECDIS, a one-dimensional GEOMETRIC PRIMITIVE of an OBJECT.
6237
look-up table

In ECDIS, a table giving symbology instructions to link SENC objects to point, line or area symbolization, and providing DISPLAY PRIORITY, radar priority, IMO category and optional viewing group.
6238
mariner’s navigational objects
In ECDIS, features other than chart objects, such as the ownship symbol and velocity vector, planned route, bearing line, etc.
6239
meta object
In ECDIS, a FEATURE OBJECT containing information about other OBJECTS.
6240
non-HO information
In ECDIS, the information contained in the SENC provided by non-HO sources (MARINER’S INFORMATION or other sources outside HOs).
