This service allows consultation of the spatial metadata of the complete collection of aerial photos of the National Geographic Institute (NGI), from 1946 to today. The data is accessible via a Web Feature Service (WFS). The collection comprises more than 100,000 aerial photos. The images are predominantly panchromatic (black and white). From the late 1970s onwards, colour images were also taken, and from the end of 2004 onwards all images were taken in colour. The analogue aerial photos in the collection were scanned in high resolution. More recent aerial photos were captured directly in digital format. This specific service includes three layers: the centroids (centre points) of the individual aerial photos, the footprints (the outlines of the area on the ground covered by each photo), and the flight paths of the aircraft used during image acquisition. For each aerial photo, all known metadata is 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. This data makes it possible to find out which aerial photos are available for a given location and period, and what the characteristics of each photo are. The aerial photos can be ordered in high resolution via https://shop.ngi.be/nl/luchtfotos/.

CadGIS Viewer is an application developed by the General Administration of Patrimonial Documentation of the FPS Finance. This application allows to: - consult the current situation of the land register plan and the administrative units and print them out; - consult all the tax situations since 2018 (situation as on 1 January) for the land register plan and administrative units; - search and geolocate the objects on the land register plan on the basis of space characteristics or queries; - ask for and print out cadastral plan parcels within a certain range around or adjacent to one or more parcels ; - search graphically on the map for surveyors' plans (only for surveyors); - add additional data to the map, both from a predefined list (IGN - Belgian national geographical institute’s aerial photographs, Cartoweb, regional reference frames such as GRB and PICC, ...) as well as other data via the URL of web services.

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

This web service allows viewing datasets from INSPIRE Contour Lines, and DTM.

This webservice allows viewing a digital surface model. It is a homogeneous and regular points grid which indicates the height above the surface of the earth, either the soil or any other permanent and visible element in the landscape (vegetation, construction,…). These data represent the situation of the landscape resulting from the July 2021 floods in het areas of the Vesdre, of part of the Meuse downstream from Liège and of the Demer. The heights are given relative to the Belgian zero level (fictitious zero of Uccle). The data have a resolution (size of the meshes of the regular grid) of 20 cm.

This web service allows viewing datasets from Buildings

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 web service allows viewing the datasets under the Marine Strategy Framework Directive (MSFD).
