Archizem's engineering team created a Digital Terrain Model (DTM) for a 21 km railway section, with a 40–60 meter buffer covering densely built-up and forested areas.
The model was generated from aerial survey point clouds, augmented by static scans in bridge areas, achieving an accuracy of 15 cm relative to the point cloud.
An important aspect of the work was developing the DTM to include selected elements of a digital surface representation. A set of extracted structural breaklines was also delivered to support the subsequent creation of a detailed 1:200 topographic plan for the project area.
The DTM serves as essential baseline data for reconstruction planning, enabling the refinement of layout solutions and informed engineering decision-making.
