  1. Nitrate Directive/SoE/WFD streamlining First results - Identification of common monitoring sites 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  2. Identification of common sites between NiD and SoE and NiD and WFD ‏ • General methodology: • NiD and SoE data – period 2004 – 2007 • WFD data – 2006 and possible update later • Nid, SoE and WFD monitoring stations: selection of stations with NO3 data • 1st step: Spatial analysis comparison according to position • 2nd step: ID comparison • Synthesis 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  3. Identification of common sites between NiD and SoE and NiD and WFD ‏ • Comparison: • Separate spatial and database work • Comparison based on the same types of monitoring stations (GW, R, L, TCM) • Every country individually • Comparison of NiD and SoE data • Comparison of NiD and WFD data 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  4. Identification of common sites between NiD and SoE and NiD and WFD ‏ • Spatial Comparison: • GIS analysis • Buffer 500 m for each layer • Choosing stations in buffer –> new layers • Converse analysis – SoE cf NiD and vice versa • Main output: list of NiD monitoring stations spatially matching with SoE or WFD stations 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  5. SpatialComparison ‏ 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  6. SpatialComparison‏ 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  7. Identification of common sites between NiD and SoE and NiD and WFD ‏ • ID Comparison: • Comparison of IDs • Different ID in each database • Automatic comparison • Correct systematic errors – manual checking • Manual selection of best results • Main output: List of monitoring sites with identical ID 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  8. Identification of common sites between NiD and SoE and NiD and WFD ‏ • ID Comparison: • Station Identifiers (database columns) used for sites matching – red ones are available for 100% Stations 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  9. Identification of common sites between NiD and SoE and NiD and WFD ‏ • ID Comparison: • Example of manually searched best matching pair of codes in Surface Water Rivers - NiD 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  10. Identification of common sites between NiD and SoE and NiD and WFD ‏ • ID Comparison: • Example of manually searched best matching pair of codes in Surface Water Rivers - SoE 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  11. Identification of common sites between NiD and SoE and NiD and WFD ‏ • ID Comparison: • Example of manually searched best matching pair of codes in Surface Water Rivers - WFD 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  12. Identification of common sites between NiD and SoE and NiD and WFD ‏ • Synthesis: • 4 different categories of monitoring stations: • Bestmatch: stations with same ID and close position • Moderatematch: stations with same ID and different position • Possiblematch: stations with different ID and close position • Others (no match) 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  13. Identification of common sites between NiD and SoE and NiD and WFD ‏ • Synthesis: 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  14. Comparison - Synthesis‏ • Results: • Country level: detailedmapswithstations, notes • Europeanlevel – statistics, summarymaps 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  20. Comparison – Synthesis‏ Hana Prchalova, Silvie Semeradova, CENIA

  21. Comparison – Synthesis‏ Notes: • Rivers:NiD monitoring network significantly bigger than SoE but significantly smaller than WFD; medium (NiD – SoE) or high (WFD) proportion of best matching sites; few mistakes • Lakes: NiD monitoring network significantly bigger than SoE but significantly smaller than WFD; no best matching sites; no mistakes of NiD – SoE analysis, good spatial results (NiD – WFD) – possible problems with codes? 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  22. Conclusions‏ • ProportionofSoEandNiDstations – mostly more NiDstations; • Proportionof WFD andNiDstations – mostly more WFD stations; 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA

  23. Conclusions‏ • RiversandGroundwaters – bettermatchingthanLakesor TCM; • NiD – WFD stations – bettermatchingthanNiD – SoE; • Many problems (orpossibleproblems) withIDsandlocationof monitoring stations in different reporting; • UnclearrelationbetweenSoEandNiD (or WFD) monitoring networks 21.10. 2009Thematic Freshwater Eionet Workshop, Copenhagen Hana Prchalova, Lenka Jiraskova, Silvie Semeradova, CENIA
