This layer contains an orthophoto with a ground resolution of 40 cm of the Grand Duchy of Luxembourg from 1994. It is based on a total of 600 scanned aerial images, which were georeferenced in a first step. The high-altitude aerial survey was carried out on 31 May 1994 at a scale of 1:30,000 by the Institut Géographique National - IGN-Creil SAA (France). The origin of the images is the archives of the Administration du Cadastre et de la Topographie (ACT) in Luxembourg. The orthophoto was calculated by the Division des Géomètres et de la Photogrammétrie (DGP) of the Administration des Ponts et Chaussées (Luxembourg Road Administration).
