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.

Top10Vector – Railway network is the dataset of the railway network in Belgium. This data set includes three classes. First class: rail network kilometer markers. Second class: railway stop. Third class: railway track segments. This dataset can be downloaded via the hyperlink in 'Access'.

The reference list in Belgium for the unique abbreviations of all Belgian cities and municipalities. It also includes the submunicipalities, which do not have a clear definition.

This web service allows viewingdatasets from bpost.

Top250Map is a digital version of the NGI’s topographic cartography on a scale of 1:250 000. It is the smallest scale used by the NGI to produce a cartographic representation of Belgium. It focuses mainly on inhabited places and transport networks. The whole territory is available in one single file. This map is characterized by the great number of toponyms of inhabited places.

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 1950, 1951, 1952 and 1954, 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)

Top10Vector – Hydrography is the dataset of the Belgian hydrography. This dataset includes six classes. First class: waterway kilometer markers of the Belgian navigable waterways. Second class: watercourse surfaces. Third class: watercourse segments. Fourth class: water points, which means points where the water arrives at the surface or disappears into the subsoil. Fifth class: wetlands, which means zones where the soil is saturated or regularly flooded. Sixth class: water surfaces. This dataset can be downloaded via the link in 'Access'.

Vector dataset of aeronautical obstacles with a height of 60 meters or more above the ground. The update of this dataset takes place on a multi-year cycle; for each obstacle and for each location, the situation is indicated as applicable at the time of its last update. Based on the horizontal range of an obstacle, it is classified into one of three classes: polygonal obstacle if the smallest rectangular area enclosing the obstacle has a length and width of more than 100 meters; line obstacle if the smallest rectangular area enclosing the obstacle has a length of more than 100 meters, but a width of less than 100 meters; point obstruction in other cases.

This web service allows the visualization of altimetry data. More specifically, it allows to visualize the National Geographic Institute's digital terrain model and the contours associated with it. This service is compliant with the INSPIRE specifications.

AdminMap is the digital version of the administrative map. Two versions exist: the most complete one on the scale of 1:300 000 and a simplified version on the scale of 1:500 000. These maps show the different administrative units on the Belgian territory, from the federal State to the center of the districts for the 1:500 000. The map also shows the map grid of the National Geographic Institute. An index allows localizing the different units. The index also contains information on the linguistic statutes and on the postal codes.
