  1. Challenges to be INSPIRE compliant: CDDA into Protected Sites INSPIRE Conference 2014 – Aalborg María Cabello Pedro Mendive

  2. Summary

  3. Background • Annex 1 • Addresses • ProtectedSites • Annex 2 • LandCover • Annex 2 • Habitats & Byotopes • SpeciesDistribution • BiogeographicalRegions • Land Use

  4. The Project Common Database on Designated Areas (CDDA) in conformity with INSPIRE • evaluate the existing European CDDA data sets with the INSPIRE Protected sites Simple application schema • design and follow the transformation workflow • develop and document the conceptual mapping rules • transform the European CDDA data sets into GML • provide the approach to validation • identify open issues and draft proposals for updates

  5. Harmonization process • CDDA to INSPIRE PS • Source Data Model: • CDDA • Target Data Model: • INSPIRE ProtectedSites Simple Schema • Conceptual Mapping • MatchingTable • Tools Transformation: • Geoconverter, HALE • Tools Validation: • HALE, Oxygen, XMLSpy

  6. CDDA data model sub-set Identified tables and attributes for mapping with INSPIRE PS Simple application schema

  7. INSPIRE PS DM

  8. STEP 1: Analysing CDDA • Unique identifier • Designation of a site • Relationship to legal basis (law) • Relationship between graphics and alphanumeric information • INSPIRE PS Simple application scheme extensions • CDDA – INSPIRE PS Simple application schema Matching Table • converting CDDA data into GML format and file size • Voidable – properties with no data in INSPIRE

  9. INSPIRE PS Easy mapping Complex mapping requires additional thematic and discussions

  10. STEP 2: Conceptual Mapping • Target DM: INSPIRE PS simple • MatchingTable • Rules forEncoding • Traitment of Voidableelements

  11. Mapping Rules • Geometry: • Use only polygons • inspireID: • Localid – direct match with SITE_CODE • Namespace - Formula = EU.EUROPA.ENVIRONMENT.PS.CDDA. <PARENT_ISO>.<ISO3> • legalFoundationDate: • direct match with YEAR – right format: yyyy-mm-ddTxx:xx:xx • legalFoundationDocument • Mapping is not possible • siteDesignation • Need to extend the INSPIRE PS DM with National Designation Type Code y National Designation Type Category • siteName • Direct Match with SITE_NAME • siteProtectionClassification • Attribute doesn’t exits but can be a default value: “natureConservation”

  12. DGN, DWG, DXF, PostGIS, MySQL, SHAPE, SDE, FGDB, SQL, Oracle… INSPIRE DATA Toolkit.net • Formattransformation • Data modelmanagement • CRS transformation • Read XSD schemas • Exportto GML 3.2.1 • Formattransformation • Data modelmanagement • CRS transformation-ongoing • Read XSD schemas • Exportto GML 3.2.1 STEP 3: Transformation TOOLS • Geoconverter • Hale

  13. Encoding Rules • Geometry • Multipolygons • CRS encoding: urn:ogc:def:crs:EPSG::4258 • inspireID  • legalFoundationDate  • legalFoundationDocument  • Mapping is not possible • siteDesignation  • The corresponding attribute to percentageUnderDesignation is not explicitly provided in the CDDA • siteName  • siteProtectionClassification 

  14. Attribute: legalFoundationDocument(INSPIRE PS) Informationavailable at Data Provider…

  15. Attribute: legalFoundationDocument(INSPIRE PS) Attributetitle Attribute date

  16. Attribute: siteDesignation(INSPIRE PS) AttributedesignationScheme Attributedesignation AttributepercentageUnderDesignation

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

  18. Attribute: siteName(INSPIRE PS)

  19. STEP 4: 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. Validation • Tools forValidation: • Based on ATS of INSPIRE • Extended/specific schemas • Schematron • Oxygen XML editor • XMLSpy XML Editor – Altova • Templates

  22. STEP 5: Publication • WEB Services • WMS • WFS • CSW • Out of scope of thisproject

  23. LessonsLearned • Thematicexperts are needed • Conceptual mapping is time demanding • Realisticapproachfrom Conceptual mappingto GML encoding • Share informationabouttheprocess • Rightencodingismanagedby MIG group
