This dataset contains the orthophotos of the floodable areas along the Meuse, the Vesdre and the Demer. These orthophotos are digital aerial photographs, taken by Hansa Luftbild following the floods of July 2021, in which the systematic distortions due to the central projection, relief and the not always perfectly vertical axis of shooting have been corrected. The orthophoto thereby obtained is metrically more accurate than an ordinary aerial photograph and is highly valuable as basic information. The resolution of the data is 6.5 cm (4 cm above the Hoëgne).

Orthophotographs are digital aerial photographs that have been adjusted for lens distortion, topographic relief and camera tilt. The orthophotographs are metrically more accurate than common aerial photographs. They are very valuable as reference information and also, for instance, for surveying parcels. This cover is renewed every year by the regions. The orthophotographs are produced on the basis of digital colour aerial photography. The orthophotographs have a minimal resolution of 25 cm. A mosaic of the orthophotos can be consulted on the map viewer or via the viewservices.
