Event Description: 

The Open Geospatial Consortium (OGC) invites software developers to the May 2021 OGC API Virtual Code Sprint, to be held from May 26th to May 28 th , 2021. The code sprint will begin at 07:00am EDT on the first day, and end at 05:30pm EDT on the last day.

This code sprint is proudly supported by:



A pre-event webinar, lasting up to one hour, will take place on May 19th at 09:00am EDT. The webinar will be followed by a 30-minute workshop to prepare for the code sprint. The webinar will set out the scope of the code sprint and provide an overview of the candidate standards.

OGC has been developing a new generation of standards for building web Application Programming Interface (API) solutions that make location-referenced information more Findable, Accessible, Interoperable, and Reusable (FAIR). These draft specifications come from OGC’s effort to create modular, resource-oriented API standards that use OpenAPI for describing interfaces that offer location-referenced information over the web. 

To ensure that all of the new OGC Application Programming Interface (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.

A 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 May 2021 OGC API Virtual Code Sprint will focus on the following draft OGC API specifications:

  • OGC API – Maps
  • OGC API – Tiles
  • OGC API – Styles

The goal of the May 2021 OGC API Virtual Code Sprint will be to progress the specifications. The sprint will also help to 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 as well as visual style editors, to manage and fetch styles that consist of symbolizing instructions that can be applied by a rendering engine on features and/or coverages.

OGC invites software developers to participate in the code sprint. There will be an opportunity for joint discussion with all participants on 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 on collaboration between participants in active coding.
