Orthophoto Meuse, Vesdre and Demer
This dataset contains the orthophoto mosaics that were created following the floods of July 2021 in the valleys of the Vesdre, the Meuse and the Demer.
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 dataset includes orthophotos based on aerial photographs acquired in July 2021 by Hansa Luftbild, commissioned by the National Geographic Institute (NGI), following the floods in the zones of the Vesdre, a part of the Meuse downstream of Liège and the Demer. The resulting orthophoto mosaics are georeferenced in the Lambert 2008 coordinate system.
All orthophotos are in colour (RGB). The ground resolution (GSD) is 6.5 cm (4 cm above the Hoëgne). The spatial coverage of this dataset is limited to the affected zones.
The data can be visualized via the corresponding web service (WMS). The data is available on request via https://ngi.be/aanbod/kaarten-en-fotos/luchtfotos-orthofotos/.

- Explanation
- The dataset’s compliance with the technical requirements as defined by the Commission Regulation (EU) No 1089/2010 of 23 November 2010 has not been checked
- Statement
- The orthophotos were created from digital aerial photographs. The resolution of the aerial photographs (8 bits) is 25 cm, but they come from the original orthos with a resolution of 6.25 cm (4 cm above the Hoëgne) obtained by processing the aerial photographs taken by Hansa Luftbild on 18, 20 and 21 July at the request of the NGI over the valleys of the Meuse, the Vesdre and the Demer. The orthophotos are georeferenced in the “Lambert 2008” co-ordinate system.
