| Acronym | 6-character-code of the feature/of the attribute. | Document referred to in point 2(a) of Section 1 |
| Actor | An actor transforms an electrical quantity into another physical quantity (e.g. optical). An actor is the opposite of a sensor. | |
| AIS | On-board equipment allowing automatic identification of ships for enhanced ship monitoring as well as voyage data recording and other functions. The automatic identification system should comply with the technical and performance standards laid down in Chapter V of the SOLAS Convention (Safety of Life at Sea). | Document referred to in point 2(r) of Section 1 |
| All information density | All information density (all display) means the maximum amount of SENC information. Here, in addition to the standard display (Standard Information Density), also all other objects are displayed, individually on demand. | Section 1 of this Annex |
| Attribute | A defined characteristic of an entity (e.g. the category of a light, the sector limits, the light characteristics etc.). Definitions for diverse attributes may be derived from the Feature Catalogue for Inland ENCs referred to in point 2(h) of Section 1 of this Annex. | Document referred to in point 2(a) of Section 1 |
| Cell (chart cell) | A cell is a geographical area containing Inland ENC or bathymetric Inland ENC data. | Document referred to in point 2(a) of Section 1 |
| CIE colour calibration | Procedure to confirm that the colour specified in IHO S-52 is correctly reproduced on the ECDIS display. | Document referred to in point 2(c) of Section 1 |
| Datum | A set of parameters specifying the reference surface or the reference coordinate system used for geodetic control in the calculation of coordinates of points on the earth. Commonly datums are defined as horizontal and vertical datums separately. For the practical use of the datum it is necessary to have one or more well distinctive points with coordinates given in that datum. The horizontal datum is a set of parameters specifying the reference for horizontal geodetic control, commonly the dimensions and the location of a reference ellipsoid. (The horizontal datum must be compliant with WGS 84.) The vertical datum is a surface to which elevations and/or depths (soundings and tide heights) are referred. For elevations commonly a level (equipotential) surface, approximately the mean sea level is used, for depths in many cases low water. | Document referred to in point 2(c) of Section 1 and Document referred to in point 2(n) of Section 1 |
| Display base | Minimum information density; means the minimum amount of SENC information that is presented and which cannot be reduced by the operator, consisting of information that is required at all times in all geographic areas and under all circumstances. | Document referred to in point 2(d) of Section 1 |
