Developers Invited to Participate in the May 2021 OGC API Virtual Code Sprint

by | Apr 14, 2021

The next OGC Sprint will focus on further refining the draft specifications for OGC API – Maps, – Tiles, and – Styles.


The Open Geospatial Consortium (OGC) invites software developers to the May 2021 OGC API Virtual Code Sprint, to be held from May 26-28, 2021. The Sprint will focus on further refining the draft specifications for OGC API – Maps, – Tiles, and – Styles. Registration closes at 2:00am EDT on May 26, 2021.

OGC has been developing a new generation of standards for building web API solutions that make location-referenced information FAIR: Findable, Accessible, Interoperable, and Reusable. These draft specifications come from OGC's efforts to create modular, resource-oriented API standards that use OpenAPI for describing interfaces that offer location-referenced data over the web.

To ensure that all of the new OGC API standards are as developer-friendly, usable, and mature as possible before release, each draft specification is being put through one or more code sprints to test and improve their ˜readiness' before starting the OGC standards approval process.

An OGC Code Sprint is a collaborative and inclusive event driven by innovative and rapid programming with minimal process and organization constraints to support the development of new applications and candidate standards.

The goal of the May 2021 OGC API Virtual Code Sprint will be to refine the following draft specifications, as well as to help identify issues and options for addressing those issues:

The draft OGC API – Maps specification describes an API that presents data as maps by applying a style. The draft specification enables a client application to request maps as images. This includes the ability to specify or change parameters such as the size of an image and coordinate reference systems at the time of request. 

The draft OGC API – Tiles specification describes an API building block that can enable other OGC API implementations to serve maps or tiled feature data divided into individual tiles. The draft specification includes concepts such as tile matrix sets and tile schemes. The draft standard can be used to publish map tiles and tiled feature data (e.g. GeoJSON Vector Tiles and Mapbox Vector Tiles).

The draft OGC API – Styles specification defines a Web API that enables map servers, clients, and visual style editors, to manage and fetch styles – symbolizing instructions that can be applied to features and/or coverages by a rendering engine to produce a human-readable map.

OGC invites software developers to participate in the code sprint – OGC Members and non-members alike are welcomed. There will be an opportunity for joint discussion concerning the goals and objectives of the event, as well as the final briefing of findings and opinions of the participants. However, the majority of the time will be spent collaboratively coding.

The code sprint will begin at 7:00am US EDT on May 26, and end at 5:30pm US EDT on May 28. A pre-event webinar will take place on May 19 at 9:00am US EDT. The webinar will set out the scope of the code sprint and provide an overview of the candidate standards.

Registration for the May 2021 OGC API Virtual Code Sprint and its associated Pre-event Webinar is available here. Registration closes at 2:00am EDT on May 26, 2021. OGC is looking for sponsors for this and future Sprint events, contact us via for more information.

About OGC

The Open Geospatial Consortium (OGC) is an international consortium of more than 500 businesses, government agencies, research organizations, and universities driven to make geospatial (location) information and services FAIR – Findable, Accessible, Interoperable, and Reusable.

OGC's member-driven consensus process creates royalty free, publicly available geospatial standards. Existing at the cutting edge, OGC actively analyzes and anticipates emerging tech trends, and runs an agile, collaborative Research and Development (R&D) lab that builds and tests innovative prototype solutions to members’ use cases.

OGC members together form a global forum of experts and communities that use location to connect people with technology and improve decision-making at all levels. OGC is committed to creating a sustainable future for us, our children, and future generations.
