OGC is globally known for its proven widely implemented open standards. The OGC open consensus-based standards development process has evolved to move at the pace of innovation, with constant input from technology forecasting, practical prototyping, real-world testing, certification and compliance and community engagement. Today we are revolutionizing how geospatial/location information is shared, accessed, integrated, and analyzed via the OGC’s revolutionary APIs- the building blocks for location information.

OGC APIs are designed to make it easy for ANYONE to provide and use geospatial data on the web, and to integrate this data with ANY other type of information. 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 Standards specified in the OGC's Standards Program, but also through interoperability prototyping and testing in the OGC's Collaborative Solutions and 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. The roadmap is available for the public to view. Request access here.

What's New

OGC API standards in the news

OGC Membership approves the OGC API – Tiles – Part 1: Core specification as official OGC Standard

The OGC API - Tiles Standard defines building blocks for creating Web APIs that support the retrieval of geospatial information as tiles. Different forms of geospatial information are supported, such as tiles of vector features (“vector tiles”), coverages, maps (or imagery) and other types of geospatial information. The OGC API - Tiles standard is an alternative to the OGC Web Map Tile Service (WMTS) Standard.

API Roadmap
New OGC API Roadmap

The Open Geospatial Consortium (OGC) invites the general public to review the OGC API Roadmap. The roadmap has been moved to Productboard, a product management platform. Access to the roadmap can be requested here.

APIs for the Web

Features

Approved Standard

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

Common

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.

EDR

Approved Standard

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.

Tiles

Approved Standard

OGC API - Tiles provides extended functionality to other OGC API Standards to deliver vector tiles, map tiles, and other tiled data.

Processes

Approved Standard

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.

Coverages

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

Records

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

Styles

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

Maps

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

DGGS

Enables applications to organise and access data arranged according to a Discrete Global Grid System (DGGS).

Routes

Enables applications to request routes in a manner independent of the underlying routing data set, routing engine or algorithm.

SensorThings

The OGC SensorThings API provides an open, geospatial-enabled and unified way to interconnect Internet of Things (IoT) devices, data, and applications over the Web.

 

Compliance Testing and Certification

The executable test suite for Parts 1 and 2 of the OGC API - Features Standard 1.0 is now available.

The executable test suite for the OGC API - Environmental Data Retrieval Standard 1.0 is now available.

The executable test suite for the OGC API - Processes Standard 1.0 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 OGC's Collaborative Solutions and 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.
