  • 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.

  • This service allows the visualization of a mosaic of orthophotos made for the whole Belgian territory. Access is possible through either a Web Map Service (WMS) or a Web Map Tile Service (WMTS, more powerful). Orthophotos are digital aerial photographs that have been adjusted for lens distortion, topography 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. The orthophotographs mosaic is created based on digital, colour aerial photographs acquired by the Belgian Regions. It is georeferenced in the Lambert2008 coordinates system. This cover is renewed every year. The orthophotographs have a minimal resolution of 25 cm.

  • 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).

  • Orthophotos are digital aerial photographs that have been adjusted for lens distortion, topographic relief and camera tilt. This cover is renewed every three years.The orthophotographs have a minimal resolution of 50 cm. The dataset is generated from the harmonisation of the datasets owned by the Belgian administrative regions.The dataset is INSPIRE compliant. The dataset is downloadable per NGI mapsheet at scale 1:50000.

  • The service makes it possible to view the aerial photos with orthorectification taken by Hansa Luftbild at NGI's request following the floods of July 2021 in the areas of the Vesdre, part of the Meuse downstream of Liège and the Demer. The resolution of the original data is 6.5 cm (4 cm above the Hoëgne). The service allows the images to be viewed at a maximum resolution of 25 cm. Orthophotos are digital aerial photographs 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.

  • This is the discovery service for the metadata which are made available by the Belgian federal government. It only contains the resources which have been declared for the INSPIRE reporting, i.e. the resources which contain the keyword “reporting INSPIRE”.
