Standards developed by the members of the Open Geospatial Consortium (OGC) play a key role in
OneGeology, a global project to produce the first digital geological map of the world. OneGeology is supported by UNESCO and six other international umbrella bodies. It is the flagship project for the UN International
Year of Planet Earth 2008.
OneGeology is made possible by standards. For example, GeoSciML, is a Web-based geoscience encoding standard developed by the International Union of Geological Sciences (IUGS) / Interoperability Working Group.
GeoSciML is an "application schema" of GML, the OGC’s OpenGIS(R) Geography Markup Language Encoding Standard (GML – ISO DIS 19136) for representation of geospatial features and geometry, and GeoSciML also uses the OpenGIS Observations and Measurements (O&M) Encoding standard.
In addition to GeoSciML, OneGeology uses the OpenGIS Web Map Service Interface Standard and other OGC standards. Without such standards, geology data clients and servers around the world would not be able to interoperate across the Web as OneGeology nodes.
Unfortunately, information about the Earth’s rocks isn’t always up-to-date or usable with other data, and in some parts of the world it is not available at all. Earth and computer scientists from 79 nations set out to tackle this problem several years ago and these scientists unveiled the result of their work at the 33rd International
Geological Congress in Oslo, Norway, in August 2008.
Three key results of the OneGeology project have been identified:
– Geological maps from around the globe are accessible on the World Wide Web;
– A new web language has been written for geology which allows nations to share data with each other and the public;
– The know-how to do this is being exchanged so that all nations around the world, regardless of their development status, can take part and benefit.
OneGeology has 94 national participant geological surveys who provide data. Interested stakeholders also include members of the natural resources industry and several standards organizations. The OGC
Interoperability Institute (OGCii), a not-for-profit subsidiary of the OGC, plays an advisory role in OneGeology.
