Geographic information - Geospatial API for features - Part 2: Coordinate Reference Systems by Reference (ISO 19168-2:2022)
This document specifies an extension to the Geospatial API for Features — Part 1: Core standard that defines the behaviour of a server that supports the ability to present geometry valued properties in a response document in one from a list of supported Coordinates Reference Systems (CRS).
Each supported CRS is specified by reference using a uniform resource identifier (URI).
This document specifies:
— how, for each offered feature collection, a server advertises the list of supported CRS identifiers;
— how the coordinates of geometry valued feature properties can be accessed in one of the supported CRSs;
— how features can be accessed from the server using a bounding box specified in one of the supported CRSs; and
— how a server can declare the CRS used to present feature resources.

Information géographique - API géospatiale pour les entités - Partie 2: Systèmes de coordonnées de référence par référence (ISO 19168-2:2022)
Le présent document spécifie une extension à la norme «API géospatiale pour les entités — Partie 1: Profil minimal» qui définit le comportement d'un serveur qui est en capacité de présenter des propriétés associées à une valeur géométrique dans un document de réponse dans une liste de Systèmes de coordonnées de référence (CRS) pris en charge.
Chaque CRS pris en charge est spécifié par référence à l'aide d'un identifiant de ressource universel (URI).
Le présent document spécifie:
— comment, pour chaque collection d'entités proposée, un serveur publie la liste des identifiants de CRS pris en charge;
— comment les coordonnées des propriétés d'entités associées à une valeur géométrique peuvent être accessibles dans l'un des CRS pris en charge;
— comment les entités peuvent être accessibles depuis le serveur à l'aide d'un rectangle englobant spécifié dans l'un des CRS pris en charge; et
— comment un serveur peut déclarer le système de CRS utilisé pour présenter des ressources d'entités.
Geografske informacije - Geoprostorski API za funkcije - 2. del: Koordinatni referenčni sistemi po referenci (ISO 19168-2:2022)
Ta dokument je dodatek k standardu Geoprostorski API za funkcije - 1. del: Osrednji profil,
ki določa vedenje strežnika, ki podpira zmožnost predstavitve geometrijsko vrednotenih lastnosti
v odzivnem dokumentu na enem od seznamov podprtih koordinatnih referenčnih sistemov (CRS).
Vsak podprt CRS je določen na podlagi reference z uporabo enoličnega identifikatorja vira (URI).
Ta dokument določa:
– kako strežnik za vsako ponujeno zbirko funkcij objavi seznam podprtih identifikatorjev CRS;
– kako je mogoče dostopati do koordinat lastnosti elementov z geometrijskimi vrednostmi v enem od podprtih
CRS-jev;
– kako je mogoče dostopati do funkcij iz strežnika z uporabo omejevalnega polja, določenega v enem od podprtih
CRS-jev; in
– kako lahko strežnik navede CRS, ki se uporablja za predstavitev virov funkcij.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by the Open Geospatial Consortium (as OGC API — Features — Part 2:
Coordinate Reference Systems by Reference) and drafted in accordance with its editorial rules. It was
assigned to Technical Committee ISO/TC 211, Geographic information/Geomatics, and adopted under
the “fast-track procedure”.
The main changes are as follows:
— addition of an Introduction;
— alignment of spellings with ISO spelling rules;
— renumbering and reordering of Clauses 2-4 in order to accommodate the fixed structure of ISO
documents;
— set texts introduced in Clauses 2 and 3;

Introduction
OGC API standards define modular API building blocks to spatially enable Web APIs in a consistent way.
The OpenAPI specification is used to define the API building blocks.
The OGC API family of standards is organized by resource type. This document extends the fundamental
API building blocks for interacting with features. The spatial data community uses the term 'feature'
for things in the real world that are of interest.
For those not familiar with the term 'feature,' the explanations on Spatial Things, Features and
[6]
Geometry in the W3C/OGC Spatial Data on the Web Best Practice document provide more detail.
OGC API Features provides API building blocks to create, modify and query features on the Web. OGC
API Features is comprised of multiple parts, each of them is a separate standard. This document extends
the core capabilities specified in OGC API — Features — Part 1: Core (ISO 19168-1) with the ability to
use coordinate reference system identifiers other than the defaults defined in the core.
By default, every API implementing this document will provide access to a single dataset. Rather than
sharing the data as a complete dataset, the OGC API Features standards offer direct, fine-grained access
to the data at the feature (object) level.
The API building blocks specified in this document are consistent with the architecture of the Web.
In particular, the API design is guided by the IETF HTTP/HTTPS RFCs, the W3C Data on the Web
Best Practices, the W3C/OGC Spatial Data on the
