2The 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 ReedCTO Open Geospatial Consortium, IncWe are moving closer to the goal of a geospatially enabled web…
3What 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)

5SDI DevelopmentPre –SDI through Initial Development and Implementation1990’s – currentWeb-based, standards based understanding of value of geospatial as an integrating function for the enterpriseEarly 2000 – currentImplementation of service oriented architectures, development of implementation profiles and service chaining Web services2006 – 2009Enterprise connections enabled through semantic capabilities, embedded business processes, sensor integration, data discrimination servicesAnticipated timeframe: – 2010Intelligent 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 requestsAnticipated timeframe: 2010

The SDI movement that started back in the mid 1990’s has yielded world wide agreement on a core set of principles that has improved our ability to share geospatial information in support of a variety of mission needs.GeoparserSource: Open Geospatial Consortium

9Some Comments/Questions Open standards provide the framework for geospatial interoperability and data sharingSDI’s around the world are expressing support for interoperable solutionsAre 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?
