  2. National Geodetic Service • OUTCOMES • Compatibility of coordinates in georeferenced applications enabling their seamless integration and interoperability. • Enhanced efficiency and effectiveness of space based positioning. • Availability of authoritative time-varying data related to the Earth for geosciences and space navigation. • Readiness for society’s increasing dependence and use of “positioning” as the next utility. • Global influence and Canada enhancing Canada’s ability to leverage and benefit from global advances and expertise. Provides the Canadian Spatial Reference System (CSRS) as a national standard for geospatial and Earth sciences information. • OUTPUTS • ·Intn’l Terrestrial Ref. Frame (ITRF) and Earth Orientation Parameters (contribution to) • National Reference Frame for coordinates (NAD83) • National Vertical Reference Frame (Mean Sea Level) • Canadian Gravity Standardization Network • User access to the Reference Frames 2

  3. National Geodetic ServiceRational for scope of service • Maintain and provide standards essential to the healthy socio-economic development of a country • Role of Gov’nt S&T to support dev. and maintenance of national standards • But how much is needed - who should do it? • Maintain core activities with basic access • Conduct a study to evaluate relevance, impacts , efforts required 3

  4. Provincial Survey Agencies adopt CSRS in their jurisdiction -Partner in delivering International Services (IGS, IVS, IGGS, IERS) global frames dependant on globally distributed data natn’l ref. frames dependant on global ref. frames OGD’s (DFO, GSC, EC , NRC,…) “one person’s noise is another person’s signal” collaboration for economy of scale and/or avoid duplication Academia ( including GEOIDE NCE) collaboration for advancement of technology, theory, algorithm, transfer of technology and know how Industry Integration of CSRS standards and products in value added services, products and/or applications National Geodetic Servicelinkages and their influence on outputs to outcomes • Seamless integration of georef. info • Efficiency in positioning • Authoritative data for Earth sciences and other • Readiness for “positioning the next utility” • Global influence & leveraged benefits 4

  5. VLBI Operations Global Reference Frame Analysis Active Control System Operations Active Control System Technology Support Ntn’l Ref Frames Analysis (NAREF, NAD83)   Geoid modeling and Height Analysis  Absolute Gravimetry Gravity and Geodetic Survey Operations Database maintenance Data Distribution National Geodetic Service Activities in support of outputs ITRF /EOP Nt’l Ref Frame Vert Ref Frame Gravity Ref Frame Support Activities 5

  6. Study of Geodetic Infrastructure Required for Canada Objective: determine the appropriate focus for the National Geodetic Service and ensure business alignment Timeline:  RFP closes 29th July  Start Study ~1st Sept  Completion end of Dec. Scope of study: essential roles or functions of a spatial reference system for Canada? direct and indirect clients and what are their requirements? specific components required in a national spatial reference system? look at other countries for best practices Deliverables:       3 alternatives/scenarios to meet present and future needs cost and benefits analysis, impediments and risks roles of federal and provincial government agencies and academia. 6
