Reference	Status/Date	Name	WG
ISO 19168-1:2025	2025-01-10	Geographic information — Geospatial API for features — Part 1: Core	4
ISO 19168-1:2020	2020-09-14	Geographic information — Geospatial API for features — Part 1: Core	4

Scope

This document specifies the behaviour of Web APIs that provide access to features in a dataset independently of the underlying data store. This document defines discovery and query operations.

Discovery operations enable clients to interrogate the API, including the API definition and metadata about the feature collections provided by the API, to determine the capabilities of the API and retrieve information about available distributions of the dataset.

Query operations enable clients to retrieve features from the underlying data store based upon simple selection criteria, defined by the client.

Supporting the following Sustainable Development Goals:

	(Indirect support) ISO 19168‑1 supports reliable digital and data infrastructure by enabling interoperable, standards‑based web access to geospatial feature data. The standard facilitates scalable geospatial services and modernisation of information infrastructures across sectors.
	(Indirect support) ISO 19168‑1 enables consistent and transparent access to geospatial information, supporting evidence‑based decision‑making and accountable public services through standardised interfaces.
	(Indirect support) ISO 19168‑1 facilitates data sharing and collaboration across organisations and jurisdictions by reducing technical barriers to integrating geospatial information through common API standards.
