适用范围：This International Standard defines a conceptual schema for the spatial characteristics of coverages.Coverages support mapping from a spatial,temporal or spatiotemporal domain to feature attribute values where feature attribute types are common to all geographic positions within the domain.A coverage domain consists of a collection of direct positions in a coordinate space that may be defined in terms of up to three spatial dimensions as well as a temporal dimension.Examples of coverages include rasters,triangulated irregular networks,point coverages and polygon coverages.Coverages are the prevailing data structures in a number of application areas,such as remote sensing,meteorology and mapping of bathymetry,elevation,soil and vegetation.This International Standard defines the relationship between thedomain of a coverage and an associated attribute range.The characteristics of the spatial domain are defined whereas the characteristics of the attribute range are not part this standard.
