EuroDEM is a digital representation of the ground surface topography of Europe.
The digital surface model (DSM) 1m is a homogeneous and regular grid of points indicating the height of the earth's surface in order to model the landscape. The product "DSM1meter", abbreviated DSM 1m, gives every 1m in X and Y the height of the earth's surface, i.e. the ground or any other permanent and visible element of the landscape (vegetation, construction, ...) in relation to the Belgian zero level (fictitious zero D of Uccle). It is therefore the orthometric height, commonly called: altitude.
The hillshades are presented as a regular homogeneous grid of points indicating the grey level value resulting from their orientation with respect to the chosen fictitious light source. The 1m hillshade is the view obtained by hillshading of the 1m DTM. The 5m and 20m hillshades are the views obtained by hillshading of the 5m and 20m DTM.
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.
This dataset shows 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 digital terrain model (DTM) is a homogeneous and regular point grid indicating the elevation of the ground level in order to make a model of its surface. The 1m DTM is obtained by interpolation in Lambert 2008 of the raw height data regrouping the source data, in Lambert 72 and at 1m resolution, of the Flemish and Walloon regions. The 5m DTM has as an additional source structure lines and adapted points, during the systematic and continuous updating by photogrammetric surveys. The 20m DTM, available for free download, is obtained by resampling the 1m 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.
The contour lines are the set of lines connecting all points at the same elevation in a model used to represent the relief on a large scale.
This web service allows viewing datasets from INSPIRE Contour Lines, and DTM.
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.
