OGC 3D Data Container and Tiles API Pilot (2020)

Sat, 01 Aug 2020 00:00:00 +0000

Goal

The goal of the 3D Data Container and Tiles API Pilot is to explore an integrated suite of draft specifications for 3D tiled geospatial resources and compatibility with existing OGC 3D delivery standards such as the 3D Portrayal Service, I3S, and 3D Tiles Community Standard. This suite will support smooth transitions between 2D and 3D environments; allow applications working with 2D tiled resources to get 3D tiled resources; and enable 3D tile bounding volumes to support multiple data containers.

To achieve these goals, the Pilot will develop a draft API that is compatible with the OGC API group of standards (and candidate standards) and which allows access to, and query of, 3D geospatial data and a corresponding container format for streamed data delivery compatible with glTF. The Pilot funds a number of data server and client implementations to test the new API and data delivery. Further, the Pilot will include an analysis of characteristics and capabilities of the new API in comparison with existing or emerging 2D standards.

OGC ISG SPRINT (2020)

Sat, 01 Aug 2020 00:00:00 +0000

Goal

The goal of the Sprint was to advance the use of relevant OGC and Khronos standards in the modeling and simulation community through practical exercise and testing of the draft specification produced by the 3D Data Container and Tiles API Pilot (and the associated YouTube Playlist). Of particular interest was the handling and integration of glTF models coming from multiple sources. There was secondary interest in the spec’s implementability, consistency, completeness, and maturity. Implementation experiences obtained from the Sprint advanced the interests and work of the OGC Interoperable Simulation and Gaming Domain Working Group (ISG DWG) and of the OGC Standards Baseline in general.

Who

This initiative was sponsored by U.S. Special Operations Command (USSOCOM). Proposals from both OGC members and non-members were considered, and nine organizations were selected for participation. Stipend funding was provided to selected OGC members.

What

The event was a week-long, virtual coding sprint that prototyped organization-chosen features. A single prototype of the entire spec was not feasible, but collectively the team reached as far as possible. Here is the original Call for Participation.

The 3D Data Container and Tiles API Pilot project was built upon work from Testbeds 13 through 15, 3D Tiles, and I3S; combined with the introduction of resource-oriented OGC APIs built on the OpenAPI framework. These provided the foundation for the draft specification that was the test subject of the Sprint.

Several OGC members participated in the Pilot along with the OGC, Khronos Group, and an initiative sponsor to develop the draft spec. This spec allows 2D assets (maps, vector graphics), building data, and 3D assets (glTF models, OGC building models, digital elevations) to be used together to produce a synoptic view of the region in question.

When

The Sprint Week event took place on 21-25 September 2020. A full schedule appears below.

07 July – Call for Participation (CFP) released. 21 August – Response deadline - Bidder proposals due. 01 September – Kickoff. 21-25 September – Sprint week. 05 October – Sprint reports due from participants. 11 December Technical Committee vote to publish Engineering Report.
