OGC requests public comment on draft charter for new OGC API Catalogues and Geopose Standards Working Group

The Open Geospatial Consortium (OGC) seeks public comment on the draft Charter for a proposed ‘OGC API – Catalogues’ Standards Working Group (SWG) and Geopose Standards Working Group

The purpose of this Standards Working Group is to develop a new version of the OGC Catalogue Service standard for the World Wide Web.

The current versions of the catalogue standards (i.e. CAT 2.0, CAT 3.0) — developed in the early 2000s — are implemented in an operation-oriented XML/RPC manner that has contributed significantly to building distributed catalogue systems but this legacy no longer fits with current web search and discovery practices.

The next version (“OGC API – Catalogues”) will remedy this shortcoming and bring OGC catalogue standards into closer alignment with both modern Web usage and the practices laid out in the  Spatial Data on the Web Best Practices document jointly developed by OGC and  W3C.

The main purpose of this SWG will be to develop and propose a standard for geographically-anchored poses (geopose) with 6 degrees of freedom referenced to one or more standardized Coordinate Reference Systems.

The combination of position (up/down [z], left/right [x] and forward/backward [y]) and orientation (pitch, roll, and yaw) with 6 degrees of freedom for objects in computer graphics and robotics is usually referred to as the object’s “pose.” Pose can be expressed as being in relation to other objects and/or to the user. When a pose is defined relative to a geographical frame of reference or coordinate system, it will be called a geographically anchored pose, or ‘geopose’ for short.

An object with a geopose may be any real physical object. This includes objects such as AR display devices (proxy for a user’s eyes), vehicles, robots, or even a park bench. It may also be a digital object like a BIM model, a computer game asset, the origin and orientation of the local coordinate system of an AR device, or a point-cloud dataset. 

All physical world objects inherently have a geographically-anchored pose. Unfortunately, there is not a standard for universally expressing the pose in a manner that can be interpreted and used across the range of modern computing platforms. 

The ability to specify the geopose of any object will aid in interoperability between real world 3D spatial computing systems, such as those under development for autonomous vehicles, augmented reality (AR), 3D map visualization, or any digital representation of the physical world or part therein (digital twins).

Members of the Geopose SWG will work towards defining an interoperable way to express, record, transform, and share the geopose of objects in a consistent manner across different applications, users, devices, services, and platforms.
