The Geospatial WebThe 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, Inc
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)

Some Comments/QuestionsOpen standards provide the framework for geospatial interoperability and data sharingSDIs around the world are expressing support for interoperable solutionsAre SOAs along with ontology and semantic tools ready for incorporation into SDIs of different levels of maturity or only in the most mature?If not what is needed to stimulate implementation?

We have a social responsibility to optimize our decision making by leveraging place
We are moving closer to the goal of a geospatially enabled webThe 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 1990s 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.
OGC members are now focusing on additional standards based capabilities to geospatially enable organizational enterprises.
