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.

OGC Seeks Public Comment on OGC API - Maps - Part 1: Core Candidate Standard

The Open Geospatial Consortium (OGC) seeks public comment on the candidate OGC API - Maps - Part 1: Core Standard. Comments are due by March 6, 2024. The OGC API - Maps - Part 1: Core Standard defines a Web API that can serve spatially referenced electronic maps, whether they are static or rendered dynamically, in a manner independent of the underlying data store.

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

Common

Approved Standard

OGC API - Common specifies those building blocks that are shared by most or all OGC API Standards to ensure consistency across the family.

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.

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 API - Coverages Virtual Code Sprint

    13 February to 15 February. This will be a virtual only event. The virtual code sprint aims to advance the OGC API - Coverages candidate Standard by providing an opportunity for developers to focus on implementation of the candidate Standard over a period of three days.

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.
