Production of CORINE2000 land cover data using calibrated LANDSAT 7 ETM satellite image mosaics and digital maps in Finland

CORINE Land Cover is a Europeanwide land cover and land use classification. The CORINE2000 classification of Finland is based on automated interpretation of satellite images and data integration with existing digital map data. Satellite images are used in estimation of continuous variables describing vegetation type and coverage, as well as in updating map data. Continuous land cover variables were transformed into discrete CORINE classes by thresholding these variables according to class descriptions in CORINE nomenclature. The output of Finnish CLC2000 project consists of calibrated IMAGE2000 mosaic, national CORINE classification (25 m raster) which is generalized and vectorized to European CORINE classification. According to the first validation utilization of non-standard, automated data production approach together with exploitation of digital map data was proved to be successful in Finnish conditions.
