Implementation of Terrain and Obstacle Data (TOD) for the Benefit of Hassi Messaoud Aerodrome (DAUH)

Abstract

This project addresses the implementation of Terrain and Obstacle Data (TOD) at Hassi Messaoud Aerodrome (DAUH) in accordance with ICAO standards. TOD plays a vital role in ensuring flight safety, precision in navigation, and effective risk management by providing structured, georeferenced data on terrain and obstacles. Despite the availability of international guidelines, Algeria lacks an operational model tailored to its national context. Through the use of GIS tools—particularly QGIS—this work aims to develop a structured and reproducible TOD model that can serve as a foundation for future national deployment. The project also explores regulatory, technical, and organizational challenges, proposing a roadmap that aligns with both ICAO requirements and Algeria’s specific needs. This study thus contributes to modernizing aeronautical data management and enhancing civil aviation safety. Keywords: TOD, QGIS, DAUH, Hassi Messaoud Aerodrome, Aeronautical Data, GIS.
