摘要: Multistratified archaeological sites are important archives of past human activities, recording the superposition anthropogenic deposits over centuries and millennia. We attempted reconstruction buried geomorphic surfaces in 1.55 km2, 7 m thick, multistratified urban site Padua northern Italy, through spatial interpolation 117 elevation points relative to unique features. Key data were elevations above sea level ancient features, such as presettlement alluvial plain, roads, floors, hearths dating from Bronze Imperial Roman ages. Present surface provided by a Light Detection Ranging (LiDAR) digital model. Spline produced general-trend Iron Age (13th–10th 6th B.C.), (first century B.C. first second A.D.) levels. Validation later indicates decimeter accuracy interpolation. Geographic information system overlay operations resulted quantitative estimates vertical growth site, volumes deposits, depth burial different This research new insights on development city its relations with paleohydrography, representing starting point for assessment heritage.
