1. co-funded by the European Community eContentplus programme The NATURE-SDIplus Solution for Data Harmonisation

2. 2 PRESENTATION OVERVIEW The DH-TWG The DH methodology The procedure for data transformation The procedure for metadata transformation The guidelines The matching tables The transformation tools A practical example of data remodeling The methodology to facilitate and to monitor the status of the DH process

3. 3 Data harmonisation process involves:  Different players (data providers, technological partners, research partners)  Operational implementation of DH impacts on different tasks WHY A DH-TWG? 3 Need of a dedicated technical coordination  DH-TWG

5. THE OVERALL DH METHODOLOGY (1/3) SOURCE SIDE TARGET SIDE Selection of the target schema Analysis of the target schema Creation of the Matching table Matching analysis Data transformation HARMONISED DATASET TOOLS GUIDELINES & PROCEDURES Selection of the sample DS Analysis and schematisation of the sample DS 5

7. THE OVERALL DH METHODOLOGY (3/3) The services we have created:  Web Map Services (WMS) and Web Feature Services (WFS) for the Data  Catalogue Web Services (CSW) for the Metadata Once processed, harmonised, transformed and made accessible through the Geoportal, spatial datasets, metadata and network services (accessibility and usability) have been validated 7

8. THE PROCEDURE FOR DATA TRANSFORMATION Identify a source data model Create a simple geodata structure Fill the Data matching table Document the process Choose Transformation Tool Perform Transformation Store Transformation Rules Publish harmonised Data 8

9. Identify a source metadata profile Fill the Metadata matching table Document the process Choose Metadata Editor Create or Update Metadata Store Transformation Rules Publish harmonised Metadata THE PROCEDURE FOR METADATA TRANSFORMATION 9

10. THE GUIDELINES Procedures for metadata profile and data model implementation, including Quality control for the harmonisation process 10

11. Spatial Datasets:  Final Matching table for PS (Annex I)  Final Matching Tables for BR, HB, SD (Annex III) Metadata:  Final Matching table for PS (Annex I)  Final Matching Tables for BR, HB, SD (Annex III) THE MATCHING TABLES (1/3) 11

14. THE TRANSFORMATION TOOLS Transformation tools for metadata:  MDweb (IRD), INSPIRE Metadata Editor, CatMDEdit, GeoNetwork, MIG Metadata Editor, disy Preludio. Transformation tools for spatial datasets:  GeoConverter, GeoMedia Fusion, Humboldt Alignement Editor, Go Publisher Tools surveyed, investigated and under testing by Technical Partners, used by DPs 14

17. EXAMPLE OF APPLICATION OF DH PROCEDURE – STEP 1 STEP 1.1: Selection of the sample source dataset Natura2000 dataset of Greece, source: EIONET; free download STEP 1.2: Deep analysis of the source dataset cntrygr_ENG_SCI -SPA_Aug_2009.mdb (MS Access mdb) GR_Natura2000 _v27.shp + Commission Decision 97/266/EC of 18.12.1996 concerning a site information format for proposed Natura2000 sites 17
