Leaf scans were used for a technical comparison of different programs calculating leaf area. For this approach, a subset of leaf scans was compiled from trees in selectively logged forest at SAFE and in old-growth forest in Danum Valley and Maliau Basin, sampled during the BALI project traits campaign. Leaf area determination is compared for five different methods and twp groups of leaves: "easy" (mostly simple leaves and small to medium sized leaves that result in comparibly easy scans to analyse) and "tough" (usually big and compound leaves that lead to challenging scans with shadows). For the purpose of a methods comparison, leaf areas are not summed up per leaf or tree level but instead provided on the basis of each individual scan image.
