Geographic information – Schema for coverage geometry and functions, Part 3: Processing fundamentals

PDF Format Searchable Printable Preview Now

AS/NZS ISO 19123.3:2023 identically adopts ISO 19123 3:2023 which seeks to define a coverage processing language for server-side extraction, filtering, processing, analytics, and fusion of multi-dimensional geospatial coverages representing, e.g. spatio-temporal sensor, image, simulation, or statistics datacubes. This document uses the AS/NZS ISO 19123 1 abstract coverage model and includes regular and irregular multi-dimensional grids supported for axes that can carry spatial, temporal or any other semantics. This language provides clients access to original or derived sets of coverage information.
