The term vector data refers to data that represents the spatial configuration of features as a set of directed line segments [ISO 19123] vertical coordinate system one-dimensional coordinate system used for height or depth measurements [ISO 19111] vertical datum datum describing the relation of gravity-related heights or depths to the Earth NOTE: In most cases the vertical datum will be related to mean sea level. Ellipsoidal heights are treated as related to a three-dimensional ellipsoidal coordinate system referenced to a geodetic datum. Vertical datums include sounding datums (used for hydrographic purposes), in which case the heights may be negative heights or depths [ISO 19111]
