Abstract
This article presents a method for 3D modeling and an analysis of potential emergency helicopter landing sites using integrated LiDAR and photogrammetric data to support Helicopter Emergency Medical Service (HEMS) operations. This method integrates airborne laser scanning data, high‑resolution digital terrain and surface models, and advanced GIS tools to evaluate terrain conditions, detect obstacles, and model obstacle limitation surfaces in accordance with ICAO and national aviation regulations. This method was also tested on a section of the A4 motorway (Wrocław–Opole), identifying the most operationally favorable location. The results demonstrate the effectiveness of combining 3D geospatial data with GIS‑based analytical procedures in supporting decision‑making processes related to helicopter landing site planning. This approach can be applied to other regions and transport infrastructures to enhance emergency response capabilities. Moreover, it provides a robust framework for integrating geospatial analysis into aviation safety and urban planning initiatives.
