The transferable belief model (TBM) is used to combine the soil information from soil maps and remote sensing information from colour aerial photography in two steps, with respective assumptions about the uncertainty and reliability of data. At a first step, the soil type maps of different scales were analysed for mapping unit purity to derive a soil map with integrated uncertainty information (map₀). In the second step, belief values regarding soil type hypotheses were assigned to pixels derived from airphoto classification. The ’soil type - air photo dass’ combinations were determined according to results from tested area. This new map was combined with map₀ using TBM. Two scenarios for data reliability were studied. The resulting soil type map is depicting spatial variability visible on the airphoto, when data reliability was increased for remote sensing information. The additional values of maximum belief and weight of conflict from the TBM can be integrated into GIS as spatial uncertainty information.
