The Open GIS Consortium, Inc. (OGC), Wayland, Mass., announced that an OpenGIS Recommendation is available to the public. The paper titled, “Recommended Definition Data for Coordinate Reference Systems and Coordinate Transformation,” can be found at http://www.opengis.org/techno/specs.htm. The paper specifies a data model for metadata in support of the OpenGIS Coordinate Reference Systems and Coordinate Transformations Implementation Specifications, and specifies standard definition data for the data model. The model was developed by representatives from three OGC member organizations, BAE SYSTEMS Mission Solutions, the Petrotechnical Open Software Corporation (POSC), and Shell International Exploration and Production B.V. Comments on the paper can be forwarded to the OGC Coordinate Transformation Working Group at firstname.lastname@example.org.
