Résumé
The European Union requires member states to estimate their wine growing potential. For this purpose, most member states have developed or updated vineyard registers. The present study suggests locating vineyards using medium spatial resolution satellite imagery. The work was carried out using Landsat images that were validated for the Designation of Origin «Bierzo», León, Spain. The methodology described in this paper yields a producer�s accuracy of 0.88 and a user�s accuracy of 0.63. The vineyard areas for each municipality were estimated from the classified images by linear regression, with fits of R2 > 0.80. The method gives good results at the municipal scale.
