Welcome To The OGC APIs



The OGC API family of standards are being developed to make it easy for anyone to provide geospatial data to the web. These standards build upon the legacy of the OGC Web Service standards (WMS, WFS, WCS, WPS, etc.), but define resource-centric APIs that take advantage of modern web development practices. This web page provides information on these standards in a consolidated location.

These standards are being constructed as "building blocks" that can be used to assemble novel APIs for web access to geospatial content. The building blocks are defined not only by the requirements of the specific standards, but also through interoperability prototyping and testing in OGC's Innovation Program.
To learn more about using the OGC APIs please view our guidelines here.

The OGC API Roadmap highlights the current and planned standards efforts as well as related extensions to those standards and Innovation Program and other projects influencing and refining the process of standardization.

Developers invited to the 2nd Code Sprint for the Environmental Data Retrieval API

OGC invites developers to its next virtual Code Sprint, which will focus on refining the OGC API - Environmental Data Retrieval (EDR) candidate standard. The OGC API - EDR Sprint 2 virtual event will be held on November 9-10, 2020, from 9:00am 5:30pm US Eastern Time. Registration for the Code Sprint and an associated pre-event Webinar is at https://portal.ogc.org/public_ogc/register/202011q4_api_edr.php

ISO publishes ISO 19168-1:2020, the ISO version of OGC API - Features - Part 1: Core

The International Organization for Standardization (ISO) has now published ISO 19168-1:2020, the ISO version of OGC API - Features - Part 1: Core.

The ISO standard is called ISO 19168-1:2020 Geographic information — Geospatial API for features — Part 1: Core.

The ISO standard can be obtained from https://www.iso.org/standard/32586.html

It can also be accessed online at https://www.iso.org/obp/ui/#iso:std:iso:19168:-1:ed-1:v1:en

Executable Test Suite Available

The executable test suite for the OGC API - Features - Part 1: Core (OGC 17-069r3) is now available in the OGC Validation beta environment.

If you would like to register your product implementation:
  1. Register your implementation in the OGC database: Register
  2. Then link your implementation to the test results in the beta website.

Your implementation will then appear in the OGC database as an official implementation.

If you have any issues, please report them directly to the GitHub project page: https://github.com/opengeospatial/ets-ogcapi-features10/issues

Thank you and happy testing!



Approved Standard

OGC API - Features - Part 1: Core and Part 2: Coordinate Reference Systems by Reference are both publicly available.


OGC API - Common provides those elements shared by most or all of the OGC API standards to ensure consistency across the family. The candidate standard will soon be released for public review.


OGC API - Maps offers a modern approach to the OGC Web Map Service (WMS) standard for provision map and raster content.


OGC API - Records updates OGC’s Catalog Services for the Web by building on the simple access to content in OGC API - Features.


OGC API - Processes allows for processing tools to be called and combined from many sources and applied to data in other OGC API resources though a simple API.


OGC API - Coverages allows discovery, visualization and query of complex raster stacks and data cubes.


OGC API - Tiles provides extended functionality to other OGC API standards to deliver tiled data, such as Map Tiles.


The OGC API - Styles defines a Web API that enables map servers, clients as well as visual style editors, to manage and fetch styles...


Environmental Data Retrieval (EDR) API provides a family of lightweight interfaces to access Environmental Data resources. Each resource addressed by an EDR API maps to a defined query pattern.


OGC continues to use special events, hackathons, and sprints to validate the OGC API draft candidate standards as those standards evolve. By including the broadest possible selection of stakeholders, OGC can be confident that when the standards are published, those standards have already withstood testing and suitability evaluation.

    There will also be a pre-event held on November 4th from 9-10am EST.

OGC Web API guidelines

The OGC Architecture Board (OAB) considers architecture consistency and life cycle management of the OGC standards baseline. The OAB has developed OGC Web API Guidelines to be followed when building Web API standards. These guidelines are not mandatory or policy, rather their purpose is to assist standards developers to use common patterns and better align their efforts.

OGC API - Tiles and its refinement at the 2020 Sprint

Further testing and refinement to the OGC API - Tiles candidate standard - the spiritual successor to one of OGC’s most popular standards, the Web Map Tile Service (WMTS) - has occurred during another successful OGC Sprint. The candidate standard is just one of several efforts forming OGC’s move towards modular, resource-oriented, OpenAPI-based standards.

Supporting Documents

OGC and other documents supporting OGC API efforts.

The OGC API standards rely heavily upon fundamental concepts expressed in OGC White Papers and research and testing performed in Innovation Program activities and documented in Engineering Reports. OGC members are also specifying best practices for the use of web APIs and often share that guidance. The documents below provide some background to OGC API efforts.

Innovation Program activities

The OGC Innovation Program provides a world-recognized process for users of geospatial technology to collaborate and share the advancement of technologies for future enterprise architectures.

If you have an idea for an initiative or simply have a question or comment, contact Ingo Simonis, Head of the OGC Innovation Program.

Use of OpenAPI in legacy OGC standards

While the OGC API standards are being developed in concert around common core elements, some older OGC web service standards have been described using OpenAPI. Examples of these legacy enhancements are found below.
