Canadas Geospatial Data InfrastructureCase StudyIntroductionGeo-Connection is a national program led by natural resource Canada. It is design to use spatial selective teaching across the country and to develop the Canadian Geo-Spatial data Infrastructure (CGDI). It is online resource for spatial data which provides sharing, access and use of spatial information required to any organization. It helps to decision makers, economic, environmental, academic purposes in all the private and government sectors.Infrastructure is consists of technologies polices and standards. It allowed to share geo-Spatial information and visualization of data at all levels and on the internet.Spatial Data InfrastructureA spatial data infrastructure (SDI) is a data infrastructure implementing a framework of geographic data, metadata, users and tools that are interactively connected in order to use spatial data in an efficient and flexible way. Another description is the technology, policies, standards, h uman resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data. 1 Three Phases of Geo-Connections. Phase IIn 1999 to 2004 Geo Connections established. Geo base is developed. All the data provided on the internet by the help of GEOTANGO and the all free data provided by Google.Phase IIIn the period of 2005-2009 the geo connections is implemented and used to monitor the disease infection and threats to lives of nation successfully.Multi-Agency Situational Awareness System (MASAS) used to monitor floods.Phase IIIObjectivesIncrease awarenessProvision of integrationImplementation of national policesChallengesNew Technologies and approachesProvision of memory access to all informa... ...to spatial data. Table Joining Service (TJS)It works as front-end of WMS and provides real time mapping of spatial data. It describe tabular information linked with spatial data. Web Map Tile Service (WMTS)It provide cartographic access instead of direct access to data. Client can access data by requesting its theme. Tile mapping becomes very popular now a days. Geo PortalThe Geo-Connections Discovery Portal is a metadata catalogue that allows GIS users, producers and data providers to discover, calculate, access, visualize and bring out Canadian geospatial and geoscience data products and Web services. 3 http//geodiscover.cgdi.ca/web/guest/homeReferences1.http//en.wikipedia.org/wiki/Spatial_data_infrastructure2.http//www.nrcan.gc.ca/earth-sciences/geomatics/canadas-spatial-data-infrastructure/89023.http//geodiscover.cgdi.ca/web/guest/home
