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. The event info is at https://ogcmeet.org/events/2006tc/ From the public info page (url below) *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.
