UNE-EN ISO 19123-1:2024

This document defines a conceptual schema for coverages. A coverage is a mapping from a spatial,temporal or spatio-temporal domain to attribute values sharing the same type within the domain. Acoverage domain consists of a collection of direct positions in a coordinate space that may be defined interms of spatial and/or temporal dimensions. Examples of coverages include meshes/grids, triangulatedirregular networks, point coverages and polygon coverages. Coverages are the prevailing data structuresin a number of application areas, such as remote sensing, meteorology and mapping of bathymetry,elevation, soil and vegetation. This document defines the relationship between the domain of a coverageand an associated attribute range. The characteristics of the domain are defined whereas thecharacteristics of the attribute range are not part of this standard.
