11th Eionet Workshop on Air Quality Okt 26-27 2006

linking airbase with geo info matching airbase info with sabe info
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

linking airbase with geo info matching airbase info with sabe info1
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

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

linking airbase with geo info matching sabe codes and nuts lau codes
Linking AirBase with geo-info: Matching Sabe codes and NUTS/LAU codes
  • http://ec.europa.eu/comm/eurostat/ramon/nuts/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

11th Eionet Workshop on Air Quality Okt 26-27 2006

linking airbase with geo info results and feedback
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

11th Eionet Workshop on Air Quality Okt 26-27 2006

linking airbase with geo info results and feedback1
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

11th Eionet Workshop on Air Quality Okt 26-27 2006

future developments airbase matching and linking parameters in airbase
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)

11th Eionet Workshop on Air Quality Okt 26-27 2006

future developments airbase results of overlays in airbase
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)

11th Eionet Workshop on Air Quality Okt 26-27 2006

future developments airbase integrated control of eoi and aq questionnaires
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

11th Eionet Workshop on Air Quality Okt 26-27 2006

future developments airbase google earth
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.
