2. 11th Eionet Workshop on Air Quality Okt 26-27 2006 2 La Rochelle Contents Linking AirBase with geo-info –Matching AirBase info with Sabe info –Matching Sabe codes and national NUTS/LAU codes –Results and feedback Future developments of air quality information system AirBase –Matching results and linking parameters in Airbase –Results of overlays in AirBase –Integrated control of EoI and AQ questionnaires –Google Earth –Suggestions?

3. 11th Eionet Workshop on Air Quality Okt 26-27 2006 3 La Rochelle Linking AirBase with geo-info: Matching AirBase info with Sabe info EuroBoundaryMap (Sabe) database –European administrative units (Sabe regions with Sabe code and name) –www.eurographics.org AirBase station coordinates Search process to determine which station in which Sabe region

4. 11th Eionet Workshop on Air Quality Okt 26-27 2006 4 La Rochelle Linking AirBase with geo-info: Matching AirBase info with Sabe info Match-up process: Coarse search step based on country code and bounding box coordinates 1-3 candidate regions for each station More detail: point-inside-polygon computation

5. 11th Eionet Workshop on Air Quality Okt 26-27 2006 5 La Rochelle Linking AirBase with geo-info: Matching AirBase info with Sabe info 0 matches: –BA, CS, MK not in Sabe project –Stations with missing/zero/wrong/reversed coordinates –Inaccurate station coordinates especially stations on country borders and on islands More matches by matching Sabe names with AirBase station/city names

6. 11th Eionet Workshop on Air Quality Okt 26-27 2006 6 La Rochelle Linking AirBase with geo-info: Matching Sabe codes and NUTS/LAU codes http://ec.europa.eu/comm/eurostat/ramon/n uts/lau_en.html Linking Sabe codes with national NUTS/LAU codes: –Sabe code as (partial) combination of NUTS/LAU codes –Some countries have also local administrative codes. Matching by combining names

7. 11th Eionet Workshop on Air Quality Okt 26-27 2006 7 La Rochelle Linking AirBase with geo-info: Results and feedback 5585 stations in AirBase 5292 are matched by search process 116 are matched by combining station/city names In total: 5408 stations are matched (97%) Feedback EoI2006: –Checking the matching lists –Correct station coordinates

8. 11th Eionet Workshop on Air Quality Okt 26-27 2006 8 La Rochelle Linking AirBase with geo-info: Results and feedback City names on LAU1/LAU2 level Linking with other databases; making overlays with population, land cover maps etc. Combination with zone/agglomeration maps

9. 11th Eionet Workshop on Air Quality Okt 26-27 2006 9 La Rochelle Future developments AirBase: Matching and linking parameters in Airbase Matching parameters: Sabe code, name; refilling NUTS1/2/3 and LAU1/2 codes Linking parameters: zone and agglomeration codes (to be defined)

10. 11th Eionet Workshop on Air Quality Okt 26-27 2006 10 La Rochelle Future developments AirBase: Results of overlays in AirBase GIS overlays with population and land cover maps Results in AirBase: e.g. population numbers, city names (LAU1 or LAU2 name)

11. 11th Eionet Workshop on Air Quality Okt 26-27 2006 11 La Rochelle Future developments AirBase: Integrated control of EoI and AQ questionnaires Necessary meta info available in AirBase After importing raw data, statistics and exceedances can be calculated The export function of the DEM can be extended with the questionnaire spreadsheet prefilled with info from AirBase and the DEM A useful help functionality to fill in the questionnaire

12. 11th Eionet Workshop on Air Quality Okt 26-27 2006 12 La Rochelle Future developments AirBase: Google Earth From AirView it is possible to create a GIS map in the EEA Map Service Analogously it is also possible to create a *.kml file for Google Earth Applications: –Checking station coordinates –Insight into station surroundings –Visualisation of statistics, exceedances etc.
