Implementing CDDA Based on INSPIRE Protected Sites: Transformation Workflow Insights

This presentation outlines the process of data transformation related to the Common Data Dictionary for Protected Areas (CDDA) in alignment with the INSPIRE Directive. Key aspects include addressing GML encoding issues, validation and testing methods, and examining various tools for effective transformation. The presentation also highlights lessons learned throughout the workflow, emphasizing the importance of stakeholder collaboration and realistic approaches in transforming data models. Practical examples and recommendations for future implementations are provided.

  1. Implementing CDDA Based on the INSPIRE Protected Sites – Transformation Workflow INSPIRE Conference 2014 – Aalborg María Cabello Pedro Mendive

  2. Summary • Data transformation • GML issues • Validation and testing • Tools • Open issues • Lessons learned

  3. Data Transformation • From Conceptual toPractical • MatchingTable: Mapping thecorrespondence • Transformation: • Format • Data Model • CoordinateReferenceSystem

  4. Data Transformation • Tools requirements • Change Data Model • Read target Data Model: XSD schema. • User utilities • Change CRS • Transform Coordinates • Change format • Write GML (version required by INSPIRE): encoding

  5. GML issues • Encoding of the different elements • Direct relationship • Logical conditions • Value’s Combinations • Enumeration List • Voidable reasons • INSPIRE • ISO

  6. Attribute: geometry (INSPIRE PS) • Type of geometry • gml: Polygon (points excluded) • CRS –encoding urn:ogc:def:crs:EPSG::4258

  7. Attribute: geometry (INSPIRE PS)

  8. Attribute: inspireID(INSPIRE PS) localId: direct link namespace: created by combination

  13. Attribute: siteDesignation(INSPIRE PS) NationalDesignationCode NationalDesignationCategory IUCN

  14. Attribute: siteName(INSPIRE PS)

  15. Attribute: siteProtectionClassification(INSPIRE PS)

  16. Attribute: ID (GML encoding )

  17. Example 1 all information from CDDA is available

  18. Example 2: Some information from CDDA is not available

  19. Validation and testing • Basic: • Review GML encoding (XML editor) • Visualization: • Right geometry • Right CRS • Advanced • Abstract Test Suite (ATS) • Templatestodocumenttheprocess

  20. Validation and testing • Review of the ATS – Table

  21. Tools Used • Mapping • Matching Table • Transformation • Free and Open Source: Geoconverter and Hale • Validation • Based on ATS of INSPIRE • Extended/specific schemas • Schematron • Oxygen XML editor • XMLSpy XML Editor – Altova • Templates

  22. Open Issues • geometry • legalFoundationDocument • percentageUnderDesignation

  23. Lessonslearned • Thematicexperts are needed • Realisticapproachfrom Conceptual mappingto GML encoding • CloseCollaborationamongdifferentstakeholders: Share information! • Rightencodingismanagedby MIG group
