Context

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.

OGC API standards in the news

Card image cap
OGC Membership approves the OGC API – Processes – Part 1: Core specification as official OGC Standard

The OGC API - Processes Standard provides a means to build simple-to-understand Web APIs through which complex computational tasks - geoprocessing or otherwise - can be executed. The standard allows processes designed by geospatial experts to be integrated into workflows and applications, unlocking the value of data and making it accessible to non-experts.

Compliance Testing and Certification

The executable test suite for Parts 1 and 2 of the OGC API - Features Standard is now available.

The executable test suite for the OGC API - Environmental Data Retrieval Standard is now available in Beta.

More information about Compliance certification is on the OGC website.

Sprints

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.

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.

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.
