  1. Spatial Data Infrastructures and Spatial Ontologies and Semantics John Moeller Northrop Grumman Co-Chair of Spatial Ontology Community of Practice

  2. The Geospatial Web • “The Geospatial Web is not just a bunch of mash-ups or even the hundreds of SDI's that have been successfully deployed. The Geospatial Web is about the complete integration and use of location at all levels of the internet and the web. This integration will often be invisible to the user. But at the end of the day, the ubiquitous permeation of location into the infrastructure of the internet and the web is being built on standards. “ Dr. Carl Reed CTO Open Geospatial Consortium, Inc

  3. What is a Spatial Data Infrastructure ? • A Spatial Data Infrastructure is the “Dial-Tone” of the geospatial web • “the means to assemble geographic information that describes the arrangement and attributes of features and phenomena on the Earth” (US National Research Council) • ‘the technology, policies, standards, and human resources necessary to acquire, process, store, distribute and improve utilization of geospatial data” (US NSDI EO 12906) • “the policies, organizational remits, data, technologies, standards, delivery mechanisms, and financial and human resources necessary to ensure that those working at the global and regional scale are not impeded in meeting their objectives” (GSDI Association)

  4. SDI Key Components • Network • Spatial Data • Catalogues/Clearing Houses/Registries • Data Services • An Integrating Data Framework/Foundation • Guidelines/policies • Standards and Specifications • Metadata • Core/base data • Spatial data • Services • Institutional capacity and partnerships

  5. SDI Development • Pre –SDI through Initial Development and Implementation • 1990’s – current • Web-based, standards based understanding of value of geospatial as an integrating function for the enterprise • Early 2000 – current • Implementation of service oriented architectures, development of implementation profiles and service chaining Web services • 2006 – 2009 • Enterprise connections enabled through semantic capabilities, embedded business processes, sensor integration, data discrimination services • Anticipated timeframe: 2008 – 2010 • Intelligent SDI Networks are in place using metadata for date, service, applications and models etc, registries and catalogues, semantics, chained services, e-commerce, to provide cost/accuracy/time options to meet users requests • Anticipated timeframe: 2010

  8. Some Comments/Questions • Open standards provide the framework for geospatial interoperability and data sharing • SDI’s around the world are expressing support for interoperable solutions • Are SOA’s along with ontology and semantic tools ready for incorporation into SDI’s of different levels of maturity or only in the most mature? • If not what is needed to stimulate implementation?
