1 Challenges to be INSPIRE compliant: CDDA into Protected Sites María Cabello Pedro Mendive

2 Summary Background The project Lessons learned Harmonizati on process

3 Background Annex 1 Addresses Protected Sites Annex 2 Land Cover Annex 2 Habitats & Byotopes Species Distribution Biogeographical Regions 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 Protected Sites Simple Schema Conceptual Mapping Matching Table Tools Transformation: Geoconverter, HALE Tools Validation: HALE, Oxygen, MLSpy

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

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

10 STEP 2: Conceptual Mapping Target DM: INSPIRE PS simple Matching Table Rules for Encoding Traitment of Voidable elements INSPIRE PS Data Model Feature Type Attribute Attribute Name schema Simple geometry Class Definition Stereotype INSPIRE Theme ProtectedSite An area designated or managed w ithin a feature type Protected Sites framew ork of international, Community and Member States' legislation to achieve specific conservation objectives. Attribute Name Attribute Definition Multiplicity Value Type The geometry defining the boundary of the 1 GM_Object Protected Site. Values List id this attribute is required for proper validation scheme inspireid External object identifier of the protected site. 1 Identifier localid namespace A local identifier, assigned by the data provider. The local identifier is unique w ithin the namespace, that is no other spatial object carries the same unique indentifier Namespace uniquely identifying the data source of the spatial object legalfoundationdate legalfoundationdocument The date that the protected site w as legally created. This is the date that the real w orld object w as created, not the date that its representation in an information system w as created. A URL or text citation referencing the legal act that created the Protected Site. 1 DateTime 1 CI_Citation date date type of date (creation, publication, revision) title othercitationdetails sitedesignation The designation (type) of Protected Site. 1..* DesignationType designation The actual site designation 1 designationscheme The scheme from w hich the designation code comes 1 natura2000 emeraldnetwork ramsar UNESCOWorldHeritage

11 Geometry: Use only polygons inspireid: Mapping Rules 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 STEP 3: Transformation TOOLS Geoconverter Hale DGN, DWG, DF, PostGIS, MySQL, SHAPE, SDE, FGDB, SQL, Oracle Toolkit.net INSPIRE DATA 1. Format transformation 2. Data model management 3. CRS transformation on going 4. Read SD schemas 5. Export to GML Format transformation 2. Data model management 3. CRS transformation 4. Read SD schemas 5. Export to GML 3.2.1

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) <ps:legalfoundationdocument xsi:nil="true" nilreason="unpopulated" /> Information available at Data Provider

19 STEP 4: Validation and testing Basic: Review GML encoding (ML editor) Visualization: Right geometry Right CRS Advanced Abstract Test Suite (ATS) Templates to document the process

23 Lessons Learned Thematic experts are needed Conceptual mapping is time demanding Realistic approach from Conceptual mapping to GML encoding Share information about the process Right encoding is managed by MIG group Quality & Validation are now the main issue
