  1. SDI from a technological perspective: Architecture Arnold Bregt

  2. Do you know this building?

  3. Architecture design

  4. Construction

  5. Building regulations and standards

  6. Content • Architecture for buildings • Design • Components • Standards • Architecture for SDI • Overall design • Components • Standards

  7. Comparison bestween buildings and SDI’s • Design for Building • to • Construct • using • Material and Methods • Constrained by • Standards • Design for SDI • to • Implement • using • Software tools • based on • Standards

  8. IT Architectures • Service Oriented Architecture (SOA) • Client-Sever Architecture

  9. Client-server Architecture

  10. Example e-mail

  11. Service Oriented Arichtecture • Geoportal webapplication • Catalog service • Search mechanism • Source database • Metadata editor • Services • Internet explorer • GIS software

  12. Example: Cheaptickets

  13. SDI Architecture Definition: Structure of the system, which is formed by its components, their properties and the relationships and the interaction with the environment.

  14. Components (Béjar et al. 2009) • Components types (properties) • Connector Types • Constraints

  15. How to describe an Architecture? • It is free,but: • Try to be consistent and clear • Look at good examples (e.g. UML) • It must communicate the message

  16. Example: Geospatial portal OGC

  17. Example: SDI Galicia

  18. Example: North Rhine-Westphalia

  19. Example: GeoFoss

  20. SDI Architecture INPRIRE

  21. Software support for SDI • Con Terra - SDI suite • Geonetwork

  22. Case of the week • Your SDI as a technological infrastructure” • Please analyze the technological aspects of your case SDI. Concentrate on ICT architecture (SOA), standards and services used in your SDI case.

  23. Case of the week • With analyse we mean: • Draft an architectural picture of your SDI (design your own picture for your own SDI); • Describe the components, standards and software technologies used; • Reflect on the standards and technologies used (e.g. are they using the latest versions of the standards, what software tools are popular, etc).

  24. Case of the week • Create a Create a Table with standards and software tools used for your SDI.

  25. Case of the week • TIP 1: Study the paper of Béjar et al., 2009 • TIP 2: Use OGC and ISO as a reference source for standards (ISO) and standards and software tools (OGC).

  26. Questions?

  27. UML • UML: Unified Modeling Language • 2000 ISO Standard • Describe states and processes • Use for describing GI standards.

  28. UML

  29. Web Coverage service (WCS) • Technically, WCS Core establishes three request types, inline with the OGC Web Service definition: • GetCapabilities: delivers an XML-encoded description of service properties and the data holdings offered by the server inquired. • DescribeCoverage: delivers XML-encoded descriptions of coverages (such as their location in space and time). • GetCoverage: delivers a coverage (or part thereof), either as original data or processed, in some suitable data format.

  30. XML Aspects Example • Extensible Markup Language (XML) • Human and Machine readable • Very popular
