5. Adopting open standards & specifications from the international arena is critical Canada is building several national infrastructures:  Canadian Geospatial Data Infrastructure;  GeoScience Knowledge Initiative;  National Forest Information System;  Ocean Portal and Marine infrastructure;  National Transportation Network Key to success is seen in open standards and specifications and the SCOTS products based on the standards:  ISO TC211 and ISO JTC1 SC32  OGC (Open GIS Consortium): WMT-1,2 and now MPP;  W3C (World Wide Web Consortium): XML, XHTML;  3i (Information Interoperability Institute): Industry led group working on open source interoperbility tools based on ISO TC211 & JTC1-SC32, OGDI and OGC WMS-WFS;

6. Strategic Goals for Standards in Canada Strategic goals are to: è achieve interoperability by establishing a common information infrastructure for use by all stakeholders è promote and leverage existing and evolving Canadian Technology and expertise (e.g., CEONet, MID-C, AquaGIS, III/OGDI, and others); è gain competitive advantage by consolidating various independent Canadian initiatives; è nurture the development of Canadian expertise and products to provide entry to foreign markets è cooperate with international activities to ensure the Canadian solution is in tune with international community; è ensure the compliance of Canadian products by funding standards activities (Standards Council of Canada); è demonstrate solutions for the global delivery of integrated geospatial information, applications and services.

10. Access to Data Distributed navigation, data access, viewing and download as an implementation of: è Metadata (ISO/TC 211 19115), so we can find data to access. è Catalogs (ISO/DIS 19110) to describe the type of data we are accessing, è Simple feature Access (ISO/TC 211 19125-1 & 19125-2), l Need a common spatial Schema so we know what types we are asking for so we have TC211 19107 (Vector) and TC211 19123 (Image and Gridded Data), and l Implementations based on queries using the harmonized simple feature model interfaces implemented based on (ISO TC211 19125) è The ability to fuse and tranform information for different purposes is enabled by Spatial referencing by coordinates (ISO/TC 211 19111);

11. MetaData in Canada CTIS - National Topographic Database è Products available are described in detail using metadata stored in a database environment. As in feature catalogue, a view complying to ISO CD.3 19115, Geographic information - Metadata standard is available. Multi-lingual is supported by the databases. l Canadian Earth Observation Network (CEONet) è Various data holdings, collections and services are described using FGDC profile and communicated via a Z39.50 interface. l CGKN and other infrastructure initiatives use various metadata profiles such as: è GILS, è the Canadian Metadata Standard (171.3-95) è the Dublin Core è or a hybrid (subsets or supersets of a given specification). l Recognizing the need for a more complete, flexible and standards compatible approach GeoConnections funded the development of a next generation metadata manager and interface.

12. NTDB example of a standards based metadata & feature catalog (ISO 19110)  NTDB Feature Catalogue and Metadata è Feature Catalog: CTIS at Sherbrooke, developed a database environment to manage the feature catalogue allows us to document semantics of geospatial features and provide it according to ISO/DIS 19110, Geographic information - Feature cataloguing methodology. This environment is functional and can be consulted on Internet. è Metadata Products available are described in detail using metadata stored in a database environment. As in feature catalogue, a view complying to ISO CD.3 19115, Geographic information - Metadata standard is available. è NTDB Data as part of CGDI è Migration of the existing data (60 millions records /100 GB of data) to Oracle 8i using standardized geometries (ISO CD 19125-1, Geographic information - Simple feature access - Part 1: Common architecture and ISO CD 19125-2, Geographic information - Simple feature access - Part 2: SQL option). è This infrastructure allows to use several commercial client applications for consulting the data (locally or via Internet).
