The goal of this Sprint is to test if the draft specification and further the work being done by the OGC Interoperable Simulation and Gaming Domain Working Group being produced by the 3D Data Container and Tiles API Pilot [] is easily implementable. The results of the Sprint shall be open source and available via GitHub or GitLab.


The Sprint is currently scheduled from noon on 14 through noon on 18 September 2020. The dates may change depending on the state of Covid-19 infections and other national issues. If by August 14, 2020 there are still travel restrictions, then the Sprint will be held virtually. Additional information will be provided at notification (see Schedule [below]).


The Sprint will be at the SOFWERX [] facility at 1925 E. 2nd Ave. #102, Tampa FL. 33605. Detailed directions and contacts will be provided with your notification.

The Sprint application process is open to all organizations. This includes all member companies, individuals, teams, and Universities. OGC is actively looking for participation by organizations with geospatial experience that have not worked with OGC in the past. 


OGC develops and supports the use of Earth-based data across many users and platforms. These data exist in OGC specification formats and (non-OGC) legacy formats. A draft specification was developed to integrate the use of some of these formats for the display of 2D and 3D data into a single work environment. 

This Sprint is to test the implementability of the “OGC 3D Container and Tiles API Pilot” draft specification during a week-long coding effort. This specification defines query options for retrieving 3D tiled resources in a manner independent of the underlying data store. 3D tiled resources are inclusive of feature geometries, feature attribute values, and texture data. The specification aligns with OGC Web API Guidelines and supports multiple 3D geospatial standards included in the OGC portfolio, such as 3D Tiles, I3S, CDB, and CityGML. See OGC API [] for a list of the APIs and links to the detailed documents.

Each accepted organization will be provided with the output of the Pilot and a collection of data suitable to experiment with the draft specification. 

Anticipated Results

It is anticipated that the draft specification will be too large and complex to allow a single week of software development to test all aspects. Each organization should decide ahead of time which portions of the specification they wish to address. An important part of the results is a document from each organization that identifies the portions of the draft specification where an implementation was attempted and the results of that implementation, including comments about inconsistencies or incompleteness of the draft specification.

A public GitHub or GitLab repository will be created, and each organization will be sharing the work done during the Sprint. The details will be described in the CfP.

This is not a contest and no prizes will be awarded as a result of this Sprint. 

Call for Participation

The Call for Participation has not yet been released. The link will be posted here when it is available. See Schedule [below] for details and exact dates.


Each selected participant or organization will be provided a stipend of $15,000 to use as they see fit. This can be used to cover the cost of travel, equipment, individual funding, or miscellaneous expenses. There will be a maximum of six (6) organizations selected. Each organization is allowed up to three (3) individuals in the Sprint Work room during work hours. 

Organizations not selected for funding may choose to participate at their own expense with prior approval of OGC and the sponsor.

Sprint work environment

SOFWERX will provide a suitable work environment for up to three individuals per organization. The work environment includes the following:

  • Tables and chairs for all individuals
  • Power for all individuals
  • Internet connectivity for all individuals
  • Public GitHub or GitLab repos
  • Basic office facilities including water, toilets, air conditioning, lighting, etc.
  • Multiple white boards or paper flip boards with multi-color markers to be shared amongst the organizations

The work area will be secured when no one is present; however, neither physical nor electronic security between organizations is guaranteed.


The schedule of significant events is listed below. This is subject to change depending on different conditions, such as possible hurricanes or how the national, state (Florida), and regional (Tampa) response to the current Covid-19 pandemic. All changes to the schedule will be noted here. If there are still significant travel restrictions either nationwide or in the Tampa area, then the Sprint will be held virtually with each organization working from their designated area. All dates are 2020.
