This presentation deals with a method using wide range maps of archaeological sites to create and transform data to a downscaled regional level as a part of the LUCIFS-project. The aim of this research aims is an attempt to make an estimate with regard to population densities and their land use. In a first step the sources are judged critically. This is to be seen in combination with the background of natural landscape units. Should settlement density and land use correspond, then regions of similar geographic and geomorphologic structure and biological potency may have supported similar population densities. An independent control of these models and the intensity of human impact will come from the palynologic analysis carried out within the LUCIFS-project. The downscaling of archaeological data gives an idea as to which regions data exist and in which it is still lacking.
