Developers Invited to the 2023 OGC Tiling Interfaces Code Sprint


Sharing is Caring

Online and in-person Code Sprint will support the development and maturation of Open Standards and Projects that use tiles to transfer and represent geospatial information.

12 April 2023: The Open Geospatial Consortium (OGC) invites software developers to the OGC Tiling Interfaces Code Sprint, to be held online and in-person from June 12-14, 2023, at the Moonshot Labs of the National Geospatial-Intelligence Agency (NGA) in St Louis, Missouri, USA. Participation in the code sprint is free. Registration for in-person participation closes at 5pm EDT on May 10. Registration for remote participation will remain open throughout the code sprint.

An OGC Code Sprint is a collaborative and inclusive event to support the development of new applications and open standards, as well as to enable software developers to focus on projects that implement open geospatial standards.

OGC Code Sprints experiment with emerging ideas in the context of geospatial standards, help improve interoperability of existing standards by experimenting with new extensions or profiles, and are used for building or enhancing software products to implement the standards.

Newcomers to OGC Standards are welcomed at the sprint. The mentor stream is designed to bring developers up-to-speed on the Standards and Projects that form the focus of the sprint, while also providing them with know-how and experience that they can use and build upon even after the sprint has concluded.

The code sprint will focus on the following Standards and specifications:

  • OGC API - Tiles defines building blocks for creating Web APIs that support the retrieval of geospatial information as tiles.
  • OGC API - Maps describes an API that can serve spatially referenced and dynamically rendered electronic maps.
  • Changesets API is based on outcomes from OGC Testbed-15 and provides the foundation for a 'Transactional Tiles API Extension' for OGC API - Tiles.
  • Vector Tiles Extension to GeoPackage that describes a prototype extension of the OGC GeoPackage Standard to support the use of vector tiles technology.
  • Variable Width Tile Matrix is a grid suited for the whole globe that keeps the data in a geographic Coordinate Reference System.
  • Web Map Tile Service (WMTS) defines a web service that can serve map tiles of spatially referenced data using tile images with predefined content, extent, and resolution. Developers of implementations of the OGC WMTS Standard, DGIWG WMTS profile, and the NSG WMTS profile are particularly encouraged to attend.

Also encouraged at the Code Sprint are non-coding activities such as testing, working on documentation, or reporting issues.

The code sprint begins at 9am EDT on June 12 with an onboarding session, and ends at 5pm EDT each day. Registration is open now. Registration for in-person participation closes at 5pm EDT on May 10. Registration for remote participation will remain open throughout the code sprint.
