DSM 1m is a homogeneous and regular point grid indicating the height of the Earth’s surface level in order to model its landscape. DSM 1m is achieved by interpolating in Lambert 2008 source data in Lambert 72 and at a 1m-resolution from the Flemish and Brussels Regions, and by adding Lambert 2008 data at 1m-resolution from the Walloon Region.

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.

An hillshade is a homogeneous and regular points grid, indicating the grey tone deriving from their orientation relative to the chosen fictitious light source. The Hillshade DTM 5m is a representation of the hillshading of the DTM 5m.

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

This view service allows visualization of the Hillshade DTM1m, the shaded version of the digital terrain model at a resolution of 1m.

This view service allows visualization of the Hillshade DSM1m, the shaded version of the digital surface model at a resolution of 1m.

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.

This view service allows visualization of the IGN digital terrain model at a resolution of 5m (DTM 5m) as well as the shaded version (Hillshade DTM 5m) of it.

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.
