Preface This OpenGIS encoding specification defines the means by which the OpenGIS Geography Markup Language (GML) is to be used within JPEG 2000 images for geographic imagery. This specification is the result of work in the GML in JPEG 2000 Interoperability Experiment. In 2004, the submitting organizations introduced a candidate specification document (04-045) which later became an OGC public Discussion Paper and the basis for conducting the Interoperability Experiment. The Activity Plan for the GML in JPEG 2000 Interoperability Experiment was formally approved by the Open Geospatial Consortium in February 2005. The current revision of this specification has an augmented set of contributors and submitters than the original Discussion Paper. The additional contributors were a result of the OGC Interoperability Experiment process and specific written comments that were generated from various TC meetings as well as a 30 day public comment period. ii. Submitting organizations The following organizations submitted the original document or its revisions to the Open Geospatial Consortium, Inc. Galdos Systems Inc. LizardTech, A Celartem Company European Union Satellite Centre (EUSC) DM Solutions Group Inc (DMSG) US Geological Survey (USGS) National Mapping Division The submitting entities were grateful for the contributions from the following organizations in the development and
