In the scope of the International Civil Aviation Organization (ICAO) requiring countries and airports to provide electronic Terrain and Obstacle Data (eTOD), the Administration de la navigation aérienne has been tasked by the Government to take the steps necessary to comply with this requirement.

This Digital Terrain Model (DTM) is the result of a first LIDAR survey flight that has been done in October 2017 and is of a higher resolution than required by ICAO, thus for general purpose, harmonized according to INSPIRE requirements. For this reason this DTM also uses the national reference systems LUREF and NGL.

The data itself is split up in 4 different areas, which are specified as follows:

Area 1: The entire territory of Luxembourg;
Area 2: Terminal Control Area (this area is larger than the territory of Luxembourg);
Area 3: Aerodrome movement area;
Area 4: Category II or III operations (Runway 24).
