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 info2

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.
