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

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.

This web service allows viewing the territorial divisions that represent fully recognised Belgian geographical units. The AdminVector dataset encompasses the statistical sectors defined by the FPS Economy, the administrative units maintained by the FPS Finance and their centres, as well as the boundary stones. The datasets of the judicial cantons and judicial districts are built on the basis of their definition in the Judicial Code. The dataset of electoral cantons is built on the basis of its definition in the Electoral Code. The postal cantons dataset is based on the boundaries of the Belgian postal codes managed by bpost.

Top50Map is a digital version of the NGI’s topographic cartography on a scale of 1:50 000. The images come from the symbolisation of the objects and the themes in the topo-geographic inventory of the Belgian territory (ITGI), which is built and kept up-to-date by the NGI. It can be used for on-screen viewing or printed on scales between 1:25 000 and 1:50 000 (recommended threshold values). Top50Map is meant for regional use.

Mapindex is a WMS which allows viewing the regular index grid which has been defined on five levels for the entire Belgian territory. It has been defined in order to allow a zonal geolocation. The present version is a beta version (v2) which is submitted to the emergency services. It will evolve to a standard cartographic grid.

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 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 web service allows viewing/downloading datasets from Electricity network

This web service allows viewing datasets from Buildings

The national wastewater-based epidemiological surveillance of SARS-CoV-2 monitors the SARS-CoV-2 presence in several wastewater treatment plants across Belgium. This AtomFeed download service contains the results per treatment plant since the beginning of the surveillance in September 2020. The results consist in the SARS-CoV2 concentrations over time as well as other data needed for the interpretations such as the flow rates of the treatment plants and their covering populations.
