  • This web service allows viewing datasets from LandUse-Particular Zone

  • This service allows the visualization of historical orthophoto mosaics based on available aerial photographs covering parts of the Belgian territory. The data is accessible via a Web Map Service (WMS). Orthophotos are aerial photographs that have been geometrically corrected (orthorectified) to eliminate distortions caused by terrain relief, lens distortion, and camera tilt. Unlike raw aerial imagery, orthophotos have a uniform scale and accurate geometry, making them suitable for cartography, measurements, and visual analysis. This specific service includes historical orthophotos from 1950, 1951, 1952 and 1954, derived from aerial surveys carried out by the National Geographic Institute (NGI). During this period, only analogue aerial photographs are available. The analogue images were scanned at high resolution and orthorectified. The resulting orthophotos were assembled into mosaics and georeferenced in the Lambert 2008 coordinate system. All orthophotos are panchromatic (black and white). The ground resolution (GSD) is 50 cm. The spatial coverage of this service is limited to the areas for which aerial photographs were available during the mentioned period. The service has been cached using the WebMercator TileMatrixSet, with a maximum scale denominator of 4,265.459167699568 metres (scale level 17)

This specific service includes historical orthophotos from 2010, 2011, 2012, 2013, 2014 and 2015, derived from aerial surveys carried out by the National Geographic Institute (NGI) and the Regions. During this period, both analogue and digital aerial photographs are available. The analogue images were scanned at high resolution and, like the digital ones, orthorectified. The resulting orthophotos were assembled into mosaics and georeferenced in the Lambert 2008 coordinate system. All orthophotos are in colour (RGB). The ground resolution (GSD) varies between 10 cm and 50 cm, depending on the sensor used and the surveyed area. The spatial coverage of this service is limited to the zones for which aerial photographs were available during the mentioned period. The service has been cached using the WebMercator TileMatrixSet, with a maximum scale denominator of 4,265.459167699568 metres (scale level 17).

  • Points Of Interest - Natural elements contains point elements relating to nature, namely remarkable trees and underground cavities in Belgium.

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

  • 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.

  • Top10Vector – Particular zones is the vector dataset of portions of the Belgian territory having a particular attribution which makes them different from the objects in the other Top10Vector-themes. This dataset includes only one class which can be downloaded via the link in 'Access'.

  • This web service allows downloading datasets from CORINE Land Cover-2018-Belgium, compliant with the INSPIRE data specifications

  • This dataset comprises historical orthophotos from the 2010s to 2019, derived from aerial surveys carried out by the National Geographic Institute (NGI). The ground sample distance (GSD) of the images ranges from 25 to 100 cm. The mosaics were created using aerial photography campaigns dating from 2010, 2011, 2012, 2013, 2014 and 2015. The original photographs were digitised and orthorectified in the Lambert 2008 coordinate system. The spatial coverage for each year corresponds to the areas for which photographs were available. High-resolution data can be ordered via https://shop.ngi.be/fr/photos-aeriennes/

  • This webservice allows viewing the Belgian topographical vector data as established by the National Geographic Institute. It gives an overview of the datasets of the Top10Vector-series which can be downloaded.
