NZS ISO 19154:2025
Geographic information – Ubiquitous public access – Reference model
This standard defines the requirements of standardisation for systems and services supporting ubiquitous public access to geographic information (UPA-to-GI) and describes a comprehensive set of fundamental facets that specify an abstract description of the elements for UPA-to-GI.
It further establishes a series of models constituting a conceptual framework that, when implemented, will support the development of a set of systems and services for enabling UPA-to-GI.
The standard was considered for adoption by the P4815 Identical Adoption of Geographic Information Standards and Technical Specifications Committee. The adoption of this standard maintains continuity with the ISO 19100 series and alignment with Australia for trans-Tasman consistency.
This standard is identical with and has been reproduced from ISO 19154:2014, Geographic information – Ubiquitous public access − Reference model.
