The Open Geospatial Consortium (OGC) has officially adopted the GMLJP2 standard proposed by LizardTech, Galdos Systems, and a consortium of additional aerospace and geospatial technology companies.
Geography markup language (GML) is a Web-authoring language for delivering and displaying geographic data over the Internet. It is based on extensible markup language (XML) and is used to define rich geospatial metadata within a JPEG 2000 (JP2) file. The new standard will drive cross-platform interoperability and rapid Internet distribution for geospatial imagery, enabling users to quickly and easily disseminate massive geospatial imagery by providing a consistent image format that is vendor-independent.
"Whether on the battlefield or a construction site for a new roadway, geospatial professionals are looking for reliable ways to distribute geographical imagery using a number of disparate software systems and platforms, and we are thrilled that the OGC has adopted the GMLJP2 standard now making such interoperability possible," said Carlos Domingo, chief executive officer of Celartem, Inc.
He added that LizardTech customers will be able to add GML metadata to their JPEG 2000 imagery using the geospatial image tools. LizardTech is developing products to support the addition of GML metadata to JP2 files. They are scheduled for availability this summer.
"GMLJP2 opens a whole new application arena for GML and enables the standardization of various kinds of satellite and aerial images," said Ron Lake, chief executive officer of Galdos Systems, Inc. "This will have a significant impact on geographic data collection worldwide."
GMLJP2 can support not only basic image information, but also geographic features, coverages, and topology, enabling new workflows (including using GML to specify which three bands a multispectral image should display, depending on the application that opens it and using sensor model information embedded in the GML to determine how an image should be rendered).
