摘要
The Geoscience Markup Language(GeoSciML)has been developed to enable the interchange of geoscience information,principally that portrayed on geological maps as well as boreholes.A GeoSciML testbed was developed both to test the implementation of the data model and its application in web services.The OneGeology-Europe project aims to use the GeoSciML data model,and build on the experience of the GeoSciML testbed,in implementing a geoportal for a harmonised geological map of Europe at 1:1 million scale.This involves the integration of web services from 20 participating organisations.An important objective of OneGeology-Europe is to contribute to Infrastructure for Spatial Information in the European Community(INSPIRE),both through the development of a geological data specification and the use of the INSPIRE technical architecture.GeoSciML and the OneGeology-Europe project are also steps towards incorporating geoscience data into a Digital Earth.Both the development of GeoSciML and the implementation of web services for GeoSciML and OneGeology-Europe,have followed a standards-based metho-dology.The technical architecture comprises a geoportal providing access to a Catalogue Service for the Web for metadata describing both the data and services available.OneGeology-Europe will provide bothWeb Map Services view andWeb Feature Services download services,which aim to be compliant with the INSPIRE implementing rules.
