This dataset contains the spatial metadata of the collection of historical aerial photographs (1946–2007) of the National Geographic Institute (NGI). The aerial photographs themselves are not part of the dataset. The collection comprises more than 72,000 aerial photographs. The images are predominantly panchromatic (black and white). From the late 1970s onwards, colour images were also acquired, and from late 2004 onwards all images were acquired in colour. The analogue aerial photographs in the collection were scanned at high resolution. This specific dataset comprises three layers: the centre points (centroids) of the individual aerial photographs, the footprints (the outlines of the area on the ground covered by each photograph) and the flight paths of the aircraft used during image acquisition. For each aerial photograph, all known metadata are included in the attribute table, such as the acquisition date, the flight and the strip, the dimensions, the scale, the ground resolution, the radiometry (black and white or colour), the coordinates of the centre point and the camera, lens and film used. These data make it possible to look up which historical aerial photographs are available for a given location and period, and what the characteristics of each photograph are. The data can be consulted via the corresponding web service (WFS). The aerial photographs can be ordered in high resolution via https://shop.ngi.be/nl/luchtfotos/.

This dataset contains the orthophoto mosaics that were created following the floods of July 2021 in the valleys of the Vesdre, the Meuse and the Demer. 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 dataset includes orthophotos based on aerial photographs acquired in July 2021 by Hansa Luftbild, commissioned by the National Geographic Institute (NGI), following the floods in the zones of the Vesdre, a part of the Meuse downstream of Liège and the Demer. The resulting orthophoto mosaics are georeferenced in the Lambert 2008 coordinate system. All orthophotos are in colour (RGB). The ground resolution (GSD) is 6.5 cm (4 cm above the Hoëgne). The spatial coverage of this dataset is limited to the affected zones. The data can be visualized via the corresponding web service (WMS). The data is available on request via https://ngi.be/aanbod/kaarten-en-fotos/luchtfotos-orthofotos/.

This dataset contains historical orthophoto mosaics based on available aerial photographs covering parts of the Belgian territory. 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 dataset includes historical orthophotos from 2010, 2011, 2012, 2013, 2014 and 2015, derived from aerial surveys carried out by the National Geographic Institute (NGI) and the Regions. During this period, 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. All orthophotos are in colour (RGB). The ground resolution (GSD) varies between 10 cm and 50 cm, depending on the sensor used and the surveyed area. The spatial coverage of this dataset is limited to the areas for which aerial photographs were available during the mentioned period. The data can be visualized via the corresponding web services (WMS/WMTS). The orthophotos and the original aerial photographs can be ordered in high resolution via https://shop.ngi.be/nl/luchtfotos/.

This web service allows viewing the territorial divisions that represent fully recognised Belgian geographical units. The AdminVector dataset encompasses the statistical sectors defined by the FPS Economy, the administrative units maintained by the FPS Finance and their centres, as well as the boundary stones. The datasets of the judicial cantons and judicial districts are built on the basis of their definition in the Judicial Code. The dataset of electoral cantons is built on the basis of its definition in the Electoral Code. The postal cantons dataset is based on the boundaries of the Belgian postal codes managed by bpost.

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 1947 and 1948, derived from aerial surveys carried out by the National Geographic Institute (NGI). During this period, only analogue aerial photographs are available. The analogue images were scanned at high resolution and orthorectified. The resulting orthophotos were assembled into mosaics and georeferenced in the Lambert 2008 coordinate system. All orthophotos are panchromatic (black and white). The ground resolution (GSD) is 50 cm. The spatial coverage of this service is limited to the areas 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).

Mapindex is a WMS which allows viewing the regular index grid which has been defined on five levels for the entire Belgian territory. It has been defined in order to allow a zonal geolocation. The present version is a beta version (v2) which is submitted to the emergency services. It will evolve to a standard cartographic grid.

The spatial coverage of this service is limited to the affected zones.
