Abstract

This study aimed at combining information from both remote sensing and forest inventory statistics in order to improve the knowledge on the distribution of forests in Europe. For each of the EU-15 countries the target was to produce a NOAA-AVHRR-based forest map which corresponds to the official statistics reported for the regional or province level. The statistical data were based on the European forest statistics compiled by the Statistical Office of the European Communities, Eurostat. The target variables were forest, other wooded land and other land. A reflectance image mosaic of 49 images acquired from the AVHRR instrument of NOAA 14 satellite was used as the reference satellite data. The Corine Land Cover database was selected as the most appropriate database for representing ground data. In a first phase, the percentage forest proportion was estimated for each AVHRR pixel, using the Corine land use classification as training data to establish the link between the five classes (forest, other wooded land, and within the forest class, coniferous, broadleaf and mixed forest) and the AVHRR spectral response. In a second phase, the area of each class was calibrated (based on the concept of a confusion matrix) in order that the computed forest areas corresponded to the reported area of forest land within the NUTS (Nomenclature of Territorial Units for Statistics) regions (Eurostat). Total forest was mapped for the entire European Union using National-level (NUTS 0) or sub-national level statistics i.e., NUTS-1 and NUTS-2 respectively. Benefits and limitations of the method are discussed in this paper. In summary the ethodology of calibration itself proved to be well suited to the problem of combining two independent data sources to one value-added product.
