| OGC Approves GML in JPEG 2000 Specification The Open Geospatial Consortium Inc. (OGC) membership has approved the OpenGIS GML in JPEG 2000 for Geographic Imagery (GMLJP2) Implementation Specification. The Geography Markup Language (GML) is an XML grammar for the encoding of geographic information. JPEG 2000 is a wavelet based image compression standard that provides the ability to include XML data for description of the image within the JPEG 2000 data file. This OpenGIS Implementation specification defines the means by which the OGC Geography Markup Language (GML) is to be used within JPEG 2000 images for geographic imagery. Further, the specification also provides packaging mechanisms for including GML within JPEG 2000 data files as well as specific GML application schemas to support the encoding of images within JPEG 2000 data files. The following organizations submitted the specification to the OGC for consideration as a standard: Galdos Systems Inc.; LizardTech; European Union Satellite Centre (EUSC); DM Solutions Group Inc (DMSG); and the US Geological Survey (USGS) National Mapping Division. The submitting organizations were grateful for contributions from the following companies in the development and revision of this specification: BAE SYSTEMS - Information Systems Sector; Boeing S&IS Mission Systems; Intergraph Corporation; ITT Industries Space Systems Division; PCI Geomatics Inc.; SPOT Image (SPOT); and the US National Aeronautics and Space Administration (NASA). Public comments on the draft specification were solicited, received and reviewed before the specification was finalized and voted upon. OGC is an international industry consortium of more than 300 companies, government agencies and universities participating in a consensus process to develop publicly available interface specifications. OpenGIS Specifications support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. The specifications empower technology developers to make complex spatial information and services accessible and useful with all kinds of applications. write your comments about the article :: © 2006 Computing News :: home page |
