The advences of new spatial information technologies has revolutionized the field of landscape assessment, providing tools that offer unprecedented accuracy and detail in the visualization of physical spaces. This research focuses on the exploration of two cutting-edge technologies: High-Resolution Digital Elevation Models (DEMs) and 3D models derived from historical photographs. These technologies hold the promise of enhancing our understanding of landscapes by allowing for the detailed analysis and reconstruction of both current and historical topographies. The study investigates the potential of high-resolution DEMs to deliver detailed topographical data, and examines how 3D models created from historical aerial photographs can facilitate the tertiary reconstruction of past landscapes, thereby offering a novel perspective on landscape changes over time. By employing a combination of geospatial analysis techniques and comparative evaluations, this research aims to assess the effectiveness of these technologies in improving the accuracy and depth of landscape visualizations. The findings are expected to demonstrate the significant benefits of integrating high-resolution DEMs and 3D historical reconstructions into the practice of visual landscape assessment, highlighting their value in landscape plannning and management.
