AS/NZS ISO 19123.1:2023
[Current]Geographic information - Schema for coverage geometry and functions, Part 1: Fundamentals
AS/NZS ISO 19123.1:2023 identically adopts ISO 19123 1:2023 which defines a conceptual schema for coverages, i.e. mapping from a spatial, temporal or spatiotemporal domain to attribute values sharing the same attribute type
