Lineage
Process Step

11 Land use/land cover classes were differentiated using a hierarchical decision tree classification applied on 1-km resolution AVHRR data for the period April 1992-March 1993. Afterwards a correction was applied to convert wrongly classified 'irrigated' pixels on steep slopes and mountain tops into 'undifferentiated cover of mountain and hills'.For more details is referred to the citation (De Pauw, 2008) and cross-citation (Celis, De Pauw & Geerken, 2007)
