The Open Geospatial Consortium (OGC) international geospatial standards body is seeking opinions on a Geography Markup Language (GML) XML encoding for describing the characteristics of a moving object, such as a GPS enabled car.

The group wants to develop a standard way of describing, in simple terms, the motion of an object, such as a car driving through city streets or a person walking in a park.

The standard will fill a need for simple packets of tracking information, such as direction and speed, that can be communicated between diverse platforms and applications supporting mobile location-aware devices.

The GML encoding needs to be compatible with a wide range of other standard encodings used in other communities, such as emergency services.

The candidate standard and information on submitting comments on this document are available at www.opengeospatial.org/standards/requests/69. The public comment period closes on August 23rd, 2010.
