1 Havana, February 2007 Dale Nicholson Canadian Hydrographic Service Marine Spatial Data Infrastructure in Canada

2 Havana, February 2007 Marine Spatial Data Infrastructure in Canada National Overview SDI and the Canadian Hydrographic Service –The organization –Non navigation clients –Data management –Hydrographic information network –Water level information infrastructure Role of Hydrographic Organizations in SDI

3 Havana, February 2007 National Overview Existing Organizations –Canadian Council On Geomatics Multi governmental organization (federal, provincials, territories) –Inter-Agency Committee on Geomatics Multi departmental organization of the federal government –Canadian Geomatics Accord (2001) Aim to facilitate geospatial information sharing –Canadian Geospatial Data Infrastructure (1996) To make Canadas geospatial data bases available via the Internet GeoConnections Program : financial incentives

4 Havana, February 2007 Canadian Geospatial Data Infrastructure (CGDI) A Framework for Data Basic Principles –Collect data once and use many times –Distributed management of the data –Centralized access by communities of practice, i.e. Observatory or Observing Systems concept Sets the principles, standards and data policies for interoperability of systems

5 Havana, February 2007 Canadian Geospatial Data Infrastructure (CGDI) A Three Tier Model –Data Distributed geospatial information, such as metadata, feature data or map layers –Services Web services compliant with CGDI-endorsed standards that enable access to data or data processing –Applications Applications addressing a specific problem or issue

6 Havana, February 2007 Marine CGDI Marine Geospatial Data Infrastructure –Sub component of CGDI Web Access to Marine Information –DFO GeoPortal ( –St. Lawrence Observatory ( –COIN Pacific ( –MarInfo ( –Others

7 Havana, February 2007 Canadian Hydrographic Service (CHS) CHS Mandate –Maritime navigation safety and efficiency –Tides, Currents and Water Levels –Seabed mapping for sustainable development –National sovereignty, security and emergency preparedness

8 Havana, February 2007 CHS Statement of Direction The Canadian Hydrographic Service is enhancing its role as an organization recognized as the official provider of national hydrographic information. To realize this goal, the CHS is realigning its activities towards data accessibility and the integration of marine information in support of the safe and efficient use of our waterways, the sustainable development of Canadas oceans and inland waters, and national sovereignty and security.

9 Havana, February 2007 CHS Business Model Non Navigation Clients Management and Administrative support Technical support, development, research Data TransformationData AcquisitionData Integration Data Dissemination Navigators

10 Havana, February 2007 Non Navigation Clients Source data requests : The sample : one CHS region over 2 years Growth of requests : 50% from 2004 to % for bathymetry, 12% for shoreline, limits, infrastructure Usage: –38% engineering projects and studies –27% scientific projects –23% navigational aids planning –12% others (court case, displays, planning, etc.)

11 Havana, February 2007 Data Management in CHS Dissociation of Source Data and Product Data Source Data Management Principles: –Systematic data integration for all new sources –Identify the best data (most recent, most accurate) –No cartographic transformation –Conservation of all data traceability –No data creation and no movement of data between sources

12 Havana, February 2007 Hydrographic Information Network (HIN) Metadata Management System –Centralized national DB for source information and products Source Data Management Systems –Databases decentralized in the geographic regions Product Management System –Databases decentralized in the geographic regions

13 Havana, February 2007 HIN Simplified Architecture

14 Havana, February 2007 HIN - Work in Progress Implementation of CARIS Hydrographic Production Database (HPD) for Source and Product Data Management Implementation of the Bathymetric Data Base Develop and Provide a New Product for Non- Navigational Purposes Experiment with the use of Navigation Surfaces" in Chart Production and Bathymetric Data Management

15 Havana, February 2007 Bathymetric Densities Surface Density –Nodes (points), with attributes. Density reflects spatial resolution of the sonar. Too high => unnecessary nodes; too low => seafloor detail is lost Full Density Full Density (archived) –Complete set of raw and processed data from all sensors including tides, corrections, total propagated error (TPE), other. Product Density –Soundings, optionally with attributes. Density adjusted to the needs of the product. –The database may contain the product surface or the information to be able to recreate it. Product Density

16 Havana, February 2007 Water Level Infrastructure Network of 80 permanent tide gauges all accessible remotely (90% by public) St. Lawrence tide gauges linked to a network infrastructure providing real time water levels and forecasting Used for maritime traffic management, optimization of security and transits Tsunami warning systems in Pacific and Atlantic

17 Havana, February 2007 Sineco – Work In Progress Part of the Integrated Marine Information Infrastructure (St. Lawrence Observatory) –Base chart data, real-time water levels, currents, winds, ice, other vessel movements (Automated Identification System), dense bathymetry all integrated for e-Navigation –Interoperability based on the ISO standards –Service Oriented Architecture (SOA) based on open standards

18 Havana, February 2007 Role of Hydrographic Offices in SDI The official source for, but not limited to: –Bathymetric data –Seabed information –Water level information This should be well communicated and officially recognized Advanced by being very active in international standards development and activities
