I found from my own archives a document with title "Storing Geo-Location Metadata in JPEG 2000 files using the OpenGIS GML Standard" by fellows Simon Cope (Earth Resource mapping Ltd.), David Taubman (Kakadu Software), Klaus Jung (AlgoVision-LuraTech GmbH.), Guillaume de Bailliencourt (Morgan Multimedia) and Ivan Fox (Yakoa). The document has been available from the ER Mapper web site but it is gone with the company. In that document reads "The origin element is required, shall have an id of "JPEG2000_Origin", and the Point specifies the coordinate of the bottom-left corner of the bottom-left cell in the image". OGC has obviously dropped the JPEG2000_Origin id and requirement of bottom-left corner. Whatever has happened to origin being in the corner of the corner cell, it makes it more understandable that a successor of one of the above mentioned companies seems to use it. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
