TopoMaps is a WMS allowing visualizing all images corresponding to the standard topographic cartographies made by the National Geographic Institute. As a result, it allows viewing cartographies on a 1:25 000 scale (Top25Map), on a 1:50 000 scale (Top50Map), on a 1:100 000 scale (Landcover100Map) and on a 1:250 000 scale (Top250Map), as well as the administrative map (AdminMap). With the exception of the administrative map, the cartographies show all themes of the topo-geographic inventory of the Belgian territory (ITGI) which is made and kept up-to-date by the National Geographic Institute: land use, transport, hydrography, buildings and constructions, relief, map lettering and toponyms.

This service allows the visualization of a mosaic of orthophotos made for the whole Belgian territory. Access is possible through either a Web Map Service (WMS) or a Web Map Tile Service (WMTS, more powerful). Orthophotos are digital aerial photographs that have been adjusted for lens distortion, topography and camera tilt. The orthophotographs are metrically more accurate than common aerial photographs. They are very valuable as reference information and also, for instance, for surveying parcels. The orthophotographs mosaic is created based on digital, colour aerial photographs acquired by the Belgian Regions. It is georeferenced in the Lambert2008 coordinates system. This cover is renewed every year. The orthophotographs have a minimal resolution of 25 cm.

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.

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 datasets from Buildings

This dataset contains a set of Points Of Interest (POI) indicating the location of places of interest in Belgium, collected by NGI. The dataset consists of 97 POI types grouped into 6 classes (natural elements, cult elements, patrimonial elements, elements of general interest, infrastructures, economy). POI types that have a link with the NGI topographic reference data are systematically monitored to ensure consistency between these data. But for other POI types, there is no guarantee of completeness and correctness. These are updated ad hoc when an error or incompleteness is noticed.

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.

CartoWeb.be is a Web Service (WMTS/WMS) containing cartographic representations covering 11 scale levels. CartoWeb.be offers a cartographic representation which has been developed specifically for on-screen viewing of the NGI’s most recent vector data sets. Three versions are available for the Belgian territory: 1) a TOPO layer containing a cartographic representation at all scales; 2) a GREY layer, which is the symbolisation in different shades of grey and blue of the TOPO layer. It constitutes an ideal map background; 3) an OVERLAY (1:2 500 - 1:25 000) layer destined to be used as an overlay on other data (orthophotographs for instance). This layer contains the symbolisation of a few layers only. A fourth layer, CROSSBORDER, is available in order to allow viewing (only on the smallest scales) the European context of Belgium. The extent of this representation is limited and could change in the following versions. It is best to combine the CROSSBORDER layer with the TOPO layer.

This web service allows viewing the Belgian topographical vector data as established by the National Geographic Institute. It gives an overview of the data sets of the Top10Vector-series which can be purchased.

The Solar Ultraviolet - Visible Irradiance Monitoring network (SUVIM) is formed of observation stations operated by the Royal Belgian Institute for Space Aeronomy (IASB-BIRA). At each station, UV solar radiation is measured by several instruments. The network produces UV indices, solar irradiances and ancillary measurements such as meteorological conditions at the stations in quasi-real time. The SUVIM Station Network dataset includes information on the stations. It does not include the measured data, which form the SUVIM Observations dataset.
