Recherche de motifs et cartographie des surfaces agricoles. Des relevés de terrain aux données satellitaires : application au Mali

Countryside automatic cartography is a real and decisive challenge in the current societal context (e.g., the famine risk analysis, the deforestation consequence analysis). In this paper, we propose a preliminary approach allowing the landscape characterization. More precisely, an itemset-based-technique is developed to extract crop types features. One of the main strengths of the proposed methodology is to combine both indicators extracted from satellite image and data collected from a site survey. The approach was run on data associated to Mali in collaboration with some domain experts. MOTS-CLÉS : Fouille de données, itemsets fréquents, image satellite, occupation du sol
