Whole of marks whose height with respect to the zero mark of the second general leveling is known.

The eTOD digital terrain model (DTM) is a homogeneous and regular point grid that models the height of the ground level for Belgian territory and the height of the sea level in the maritime zone. The primary source is the NGI DTM 5m, which is itself compiled based on the most recent altimetry data of the three Belgian regions and is periodically updated per map sheet at a scale of 1:50,000 using recent stereoscopic aerial images. Where available, updates from the notification platform for aviation obstacles and terrain changes are also integrated. For this DTM, the resolution (1 arcsecond) and the coordinate reference system (WGS84 + EGM2008) are used as defined in the eTOD specifications.

CORINE Local Components is an INSPIRE compliant WMS service showing 4 "Local component products" covering the Belgian territory within the framework of a Pan-European coverage. The 4 layers cover 4 different products: Urban Atlas 2012, Urban Atlas 2012 Street Tree Layer, Riparian Zones and Natura2000.

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.

This web service allows viewing/downloading datasets from Electricity network

Web service with currently available electronic terrain and obstacle data in Area 1 related to: - Implementing Regulation (EU) No 2017/373 on, inter alia, the common requirements for air navigation service providers, as subsequently amended; - Annex 15 to the Chicago Convention on International Civil Aviation; - ICAO document 10066 PANS-AIM: Procedures for air navigation services, Aeronautical Information Management.

‘Top10Vector – Railway network’ is the dataset of the railway network in Belgium. This dataset includes 3 feature types, namely the railway track segments [RA_railwaytracksegment], railway stops [RA_railwaystop] and railway kilometer markers [RA_railwaykilometremarker]. The dataset can be downloaded via the links in 'Access' at the bottom of this page.

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.

INSPIRE compliant discovery service for geographic information made available by the Belgian Federal Government.

CORINE Land Cover Belgium WMS is an INSPIRE compliant WMS service which represents the land use in Belgium for the years 2006, 2012 and 2018. The polygons are classified in 32 classes from CORINE Land Cover’s classes which are present in Belgium. The minimum map unit is 25 ha. The conceptual scale is 1:100 000. The data set also contains a polygon layer which represent the land use modifications of more than 5 ha between 2006 and 2012 and between 2012 and 2018.
