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
We are moving closer to the goal of a geospatially enabled web…

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

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: – 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

Easier access to multiple online info sources and services
Use and reuse different vendor solutions.
Reduce deployment costs by reusing information from other communities
Meet requirements for Citizen access.

The geospatial community has made substantial progress in advancing a set of best practices necessary to make a shared Spatial Data Infrastructure (SDI) a reality from the local to global levels. 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.

9. 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?

Can anyone in the audience think of any human activity that is not impacted by location or impacts a location?
