This web feature service allows viewing the NGI's historical aerial photos (1947-2007).

This dataset corresponds to the dataset of address points on the Belgian territory. The result is obtained by merging the three regions on the basis of XML files which has been supplied to BOSA for the cooperation agreement BeStAddress. The dataset is freely downloadable.

This service allows the visualization of historical orthophoto mosaics based on available aerial photographs covering parts of the Belgian territory. The data is accessible via a Web Map Service (WMS). Orthophotos are aerial photographs that have been geometrically corrected (orthorectified) to eliminate distortions caused by terrain relief, lens distortion, and camera tilt. Unlike raw aerial imagery, orthophotos have a uniform scale and accurate geometry, making them suitable for cartography, measurements, and visual analysis. This specific service includes historical orthophotos from 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, and 2009, derived from aerial surveys carried out by the National Geographic Institute (NGI) and the Regions. From this period onward, both analogue and digital aerial photographs are available. The analogue images were scanned at high resolution and, like the digital ones, orthorectified. The resulting orthophotos were assembled into mosaics and georeferenced in the Lambert 2008 coordinate system. The orthophotos are either panchromatic (black and white) or in colour (RGB), depending on the year and location. The ground resolution (GSD) varies between 10 cm and 100 cm, depending on the sensor used and the surveyed area. The spatial coverage of this service is limited to the zones for which aerial photographs were available during the mentioned period. The service has been cached using the WebMercator TileMatrixSet, with a maximum scale denominator of 4,265.459167699568 metres (scale level 17).
