Luxembourg & Wallonia LiDAR

Shaded relief from the Luxembourg and Walloon national LiDAR surveys, next to the governments' own aerial photos, behind a draggable swipe divider. Built for finding ruined and abandoned structures, including the ones hidden under forest canopy.

Bike trails	23,764 lines
Place names	4,583 settlements
Condition outlines	2,550 buildings
Cadastral footprints	ACT for Luxembourg, SPW PICC for Wallonia, from zoom 15.
Tools	Coordinate and address search, elevation readout, Scan (beta), four languages.

Data sources

Source	Used for
Administration du cadastre et de la topographie (ACT), geoportail.lu	Luxembourg relief, flown February 2019, 15 points per square metre, 50 cm raster. Cadastral buildings. Aerial photos from 2001 and 2025 (summer and winter), public domain (CC0).
Service public de Wallonie (SPW), geoservices.wallonie.be	Wallonia relief, LiDAR 2021 to 2022, 50 cm. PICC building footprints. Terrain elevation readout. Aerial photos from 1971, 2001 to 2003, summer 2023 and spring 2026.
OpenStreetMap contributors	Place names, ruins, bunkers, condition outlines, bike trails. Address search via Nominatim.
Open-Meteo, Copernicus DEM GLO-90	Elevation readout in Luxembourg, 90 m resolution. Not the LiDAR.
Leaflet 1.9.4	The only library. Loaded from cdnjs.

How it works

Each build is one self contained HTML file. No server, no build step, no database, no accounts, no API keys.
Every map layer comes from a public body or from OpenStreetMap. No commercial imagery is used.
Nothing is stored in your browser. The page sets no cookies and uses no local storage.
Map tiles, elevation values and address searches are requested directly from the providers listed above.

Elevation readout. In Wallonia the figure is a real 50 cm terrain model value. In Luxembourg it comes from Copernicus GLO-90 at 90 m, because no keyless elevation service exposes the Luxembourg LiDAR. The readout labels which one it used.

Scan is beta. It compares surface and terrain hillshades to find structures with no cadastral footprint. It saturates under closed canopy and it is not a survey instrument.
