 This paper proposes a methodological approach to assess land use in accordance with the requirements of the United Nations Framework Climate Change Convention, UNFCCC. It is based on the recognition of key land elements and their function, and the adoption of predominant land use criteria set out by rules. This methodology is designed to represent land use accurately using high and very high spatial resolution remote sensing data. The result is an accurate representation of land use that meets the standards of the UNFCCC. This article was authored by Danilo Malacone and Susanna Martinez.
