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.

MapIndex is a regular grid of rectangular or square cells coded with alphanumeric characters. It has been defined for the Belgian territory and allows geolacating several events. The present version is a beta (v2)version which is submitted to the emergency services. It will evolve to a standard cartographic grid.

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.

Orthophotos are digital aerial photographs in which the systematic distortions caused by the central projection, terrain relief and an image acquisition axis that is not always perfectly vertical have been corrected. The national orthophoto coverage is renewed annually. This view service makes it possible to visualise the national orthophoto mosaics for multiple acquisition campaigns from 2016 onwards for the entire territory of Belgium. A separate layer is published for each available year. In the current version of the service, the series of yearly layers runs from 2016 up to and including 2023, with 2023 being the most recent orthophoto coverage in this view service. For the 2016–2021 campaigns, the orthophotos have a spatial resolution of 25 cm throughout Belgium. From the 2022 campaign onwards, the resolution is 25 cm in Wallonia and 15 cm in Flanders and the Brussels-Capital Region. The view service is directly based on the orthophoto datasets of the Belgian administrative Regions, which are harmonised by NGI into a single national coverage without applying additional radiometric corrections. The orthophoto coverage is provided through this Web Map Service (WMS) and is intended for visualisation and use as a background map. For downloading the most recent orthophoto mosaics, reference is made to the associated dataset and download service “Orthophoto”.

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.

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 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 viewing ROB datasets. This service is compliant with the INSPIRE specifications.
