APIExecutable4/7Query nowOpen workbench Subscribe🇫🇷France

This API from Rennes Métropole provides geographic data on aeronautical clearance easements (servitudes T4-T5) affecting the local area. These easements prohibit the creation of, or require the removal of, obstacles that could pose a danger to air navigation or interfere with safety devices installed in the interest of air traffic. The dataset specifically covers height-related restrictions applicable within the airport's protected zones. It is intended for urban planning, construction, and land-use purposes near airports within the Rennes Métropole area.Des servitudes aéronautiques de dégagement comportant l'interdiction de créer ou l'obligation de supprimer les obstacles susceptibles de constituer un danger pour la circulation aérienne ou nuisibles au fonctionnement des dispositifs de sécurité établis dans l'intérêt de la navigation aérienne.
