The OGC will have their member meeting w/o 15 June. The meeting will be
conducted through GoToMeeting.
Of potential interest is the session at 10:10 on Tuesday (16 June) by
the Geopose Standards Working Group (SWG) led by Christine Perey.

*Purpose*
All physical world objects inherently have a geographically-anchored
pose. Unfortunately, there is not a standard for universally
expressing the pose in a manner which can be interpreted and used by
modern computing platforms. The main purpose of this SWG will be to
develop and propose a standard for geographically-anchored pose
(geopose) with 6 degrees of freedom referenced to one or more
standardized Coordinate Reference Systems (CRSs).
*Definition of geopose*
A real object in space can have three components of translation
– up and down (z), left and right (x) and forward and backward
(y) and three components of rotation – Pitch, Roll and Yaw.
Hence the real object has six degrees of freedom.
The combination of position and orientation with 6 degrees of
freedom of objects in computer graphics and robotics are usually
referred to as the object’s “pose.” Pose can be expressed as
being in relation to other objects and/or to the user. Some part
of the object must be recognized as the anchor (or origin) of
the position. 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.
