This web feature service allows viewing the NGI's historical aerial photos (1947-2007).

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.

Geodetic markers of which the 3D coordinates are precisely known in common Belgian reference systems.

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”.

This web service allows dowload ROB datasets. This service is compliant with the INSPIRE specifications.

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

This dataset consists of historical aerial imagery (1947-2007) commissioned by the National Geographic Institute. It includes the spatial footprints and metadata of individual photographs as well as the corresponding flight paths of the aircraft used during image acquisition.
