  • 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)

  • SDI DevelopmentPre SDI through Initial Development and Implementation1990s currentWeb-based, standards based understanding of value of geospatial as an integrating function for the enterprise Early 2000 currentImplementation of service oriented architectures, development of implementation profiles and service chaining Web services 2006 2009Enterprise connections enabled through semantic capabilities, embedded business processes, sensor integration, data discrimination servicesAnticipated timeframe: 2008 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

  • Global ParticipationSDIs at all levels join with other to form a GSDICanadaCGDIEuropeanSpatialInfrastructure.NSG

  • From a Foundation of SDI Best PracticesGeoparserReduce deployment costs by reusing information from other communitiesMeet requirements for Citizen access.Foundation for interoperable service networks Easier access to multiple online info sources and services Use and reuse different vendor solutions.

  • 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.
