True Orthophoto of the Grand Duchy of Luxembourg, winter 2019 edition

True orthophoto (true orthophoto) is calculated from the nadiral images from the February 2019 flight and has a resolution of 10 cm. ** Additional explanations:** Unlike classical orthophoto, which is rectified in relation to the field’s numerical model, true orthophoto is rectified in relation to the digital model of the surface integrating the elevation of the surface, e.g. the building. This allows the buildings to be rectified and their cant corrected. Thus, the roof of the buildings is exactly above the footprint of the buildings and there are no more spaces hidden by a cant of tall buildings. However, objects and streets under tall trees as well as moving objects can be distorted. There may also be distortions on the edge of the rectified objects depending on the images and overlaps available.
