This service allows the consultation of the spatial metadata of the collection of historical aerial photographs (1946–2007) of the National Geographic Institute (NGI). The data is accessible via a Web Feature Service (WFS). The aerial photographs themselves are not part of the service. 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 service 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 aerial photographs can be ordered in high resolution via https://shop.ngi.be/nl/luchtfotos/.

The web application G-DOC provides information on all Belgian geodetic reference points. These points can be used as starting points or checkpoints to determine coordinates according to the national reference systems. three groups of geodetic reference points are available: 3D points, altimetric points and planimetric points.

Govroam is a " wifi roaming " solution. This service offers to the users a simple and secure access to the wireless network of their institution, but also to networks of other participating institutions. A user from an organization that participates in govroam will be able to connect to any wireless access point broadcasting govroam. The data provided here makes it possible to locate these access points.

This service allows the visualization of the national orthophoto mosaics covering the entire territory of Belgium. 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 orthophotos from 2016 up to and including 2023, derived from aerial surveys carried out by the Belgian administrative Regions. A separate layer is published for each available year, with 2023 being the most recent orthophoto coverage in this service. The national orthophoto coverage is renewed annually. The orthophoto datasets of the Regions are integrated by the National Geographic Institute (NGI) into a single national coverage. Where possible, radiometric corrections are applied to ensure smooth transitions between the data of the Regions. The resulting orthophoto mosaics are georeferenced in the Lambert 2008 coordinate system. All orthophotos are in colour (RGB). For the 2016–2021 campaigns, the ground resolution (GSD) is 25 cm throughout Belgium. From the 2022 campaign onwards, the GSD is 25 cm in Wallonia and 15 cm in Flanders and the Brussels-Capital Region. The spatial coverage of this service is the entire Belgian territory. For downloading the most recent orthophoto mosaics, reference is made to the associated dataset "Orthofoto INSPIRE".

Geodetic markers of which the 3D coordinates are precisely known in common Belgian reference systems.

Network of marks whose planimetric coordinates are known with precision according to the reference systems which are used in Belgium.
