摘要：The aim of the paper is to reconstruct differences between the paleotopography and contemporary topography of the historic centre of Krakow city, Poland, during the last millennium. The paleotopography was reconstructed using published contour-line maps based on archaeological and geoengineering investigations and showing the roof of in situ fossil soil. The preliminary contour-line map represented a digital elevation model (DEM) base map. A DEM from aerial laser scanning (ALS DEM) shows the contemporary topography of Krakow city centre. The application of selected morphometric indices makes it possible to quantitatively describe changes in the spatial dimension with regard to altitude, relative heights, slope, and aspect classes. The analysis of the changes in the values of the elements of topography studied shows that, at the scale of the whole study area, a trend to flattening occurs, however this trend is locally balanced or overridden by an increase of surface unevenness.
