Geospatial Semantic Web Interoperability Experiment

Initial Plan

This Interoperability Experiment (IE) will address several important steps towards the development of a Geospatial Semantic Web (GSW), where discovery, query, and consumption of geospatial content are based on formal semantic specification. Many pieces of the GSW puzzle have been worked extensively in the last several years; this experiment aims to augment WFS/FE with a semantic query capability, through the definition of an ontology for the geospatial intelligence community.

Group Description:

1. Geography Markup Language 3.3 SWG (GML SWG)


2. Purpose of this Standards Working Group

The purpose of the GML SWG is to revise the OpenGIS® Geography Markup Language (GML) Encoding Standard. The standard is also published by ISO as ISO 19136:2007.

GML in JPEG 2000 Interoperability Experiment

This Encoding Interoperability Experiment (IE) will implement a number of prototype GMLJP2 codecs based on the specification described in the OGC Discussion Paper "GML in JPEG 2000 for Geographic Imagery". The purpose of the IE will be to confirm that the specification will support the requirements of geospatially related imagery over the Internet, and to improve the specification if it does not support these requirements.

The IE will attempt to address some of the following experiments around the use of GML in JPEG 2000 for Geospatial Imagery:

GML in JPEG 2000 for Geographic Imagery Encoding

The OpenGIS® GML in JPEG 2000 for Geographic Imagery Encoding Standard defines the means by which the OpenGIS® Geography Markup Language (GML) Standard [http://www.opengeospatial.org/standards/gml] is used within JPEG 2000 [www.jpeg.org/jpeg2000/] images for geographic imagery. The standard also provides packaging mechanisms for including GML within JPEG 2000 data files and specific GML application schemas to support the encoding of images within JPEG 2000 data files. JPEG 2000 is a wavelet-based image compression standard that provides the ability to include XML data for description of the ...
