DESCRIPTION:This presentation introduces a reproducible QGIS-based workflow
  designed to address a key challenge in archaeological landscape studies: 
 the analysis of urban organisation in contexts where large-scale excavatio
 n is limited or absent. By integrating LiDAR-derived digital elevation mod
 els (DEMs) with advanced terrain analysis techniques\, the workflow provid
 es a structured approach for extracting spatial patterns from surface morp
 hology alone.\nDeveloped entirely within an open-source QGIS environment\,
  the workflow combines relief visualisation methods (local relief model\, 
 sky-view factor\, openness)\, anisotropic least-cost path modelling\, and 
 viewshed analysis into a sequential and interoperable analytical process. 
 Rather than applying these methods in isolation\, the approach emphasises 
 their integration\, enabling the transition from micro-topographic detecti
 on to the modelling of movement corridors\, visibility patterns\, and spat
 ial organisation.\nThe workflow is demonstrated using a high-resolution UA
 V-based LiDAR dataset from the ancient city of Parion (Çanakkale\, Türki
 ye)\, where modern settlement and the limited extent of excavation constra
 in traditional archaeological interpretation. The approach demonstrates th
 at the integrated use of terrain-based analyses can reveal structured spat
 ial relationships\, including movement corridors and visual thresholds. In
  particular\, the results enable the identification of potential city gate
 s\, segments of the city’s defensive wall system\, the boundaries of fun
 erary landscapes\, and the principal urban axes of the Roman city\, includ
 ing the decumanus and cardo. These findings offer a viable framework for i
 nterpreting archaeological urban organisation prior to extensive and poten
 tially invasive archaeological excavations.\nThe primary contribution of t
 his study lies in the design of a transferable and reproducible workflow t
 hat can be directly implemented by QGIS users working with DEM data. Furth
 ermore\, it contributes to the community by demonstrating how complex terr
 ain analyses can be operationalised within a single platform\, moving beyo
 nd isolated tool use toward integrated workflow design. By explicitly stru
 cturing the analytical sequence\, defining parameter choices\, and relying
  exclusively on open-source tools\, the approach supports transparency and
  adaptability across different research contexts. It can be applicable not
  only to archaeological prospection\, but also to environmental modelling\
 , landscape planning\, and other domains requiring multi-scalar terrain an
 alysis.
