This layer contains the subdivision into tiles of the LiDAR data from 2019. The data is issued from a three-dimensional survey based on LiDAR (Light Detection and Ranging) technology. From a technical point of view, the LiDAR system, or airborne LiDAR measures the distance between the ground and the aircraft using an infrared laser beam. The resulting data is processed to produce a three-dimensional coordinate file (point cloud) with a decimeter accuracy per pixel on the ground. For this prototype around the Nordstad region, the flyover was carried out in February 2019 with a density of 15 points per square meter and a horizontal accuracy of +/- 3 cm and vertical of +/- 6 cm. The density indicates the pulses sent from the system, the density of the points measured can be higher depending on the type of surface scanned (Single reflection/multiple reflection). Point cloud - Data structure The raw data is structured in the form of tiles with a spatial extent of 500 mx 500 m, they contain on average between 5 and 7 million measured points. To simplify the downloading of the data, the raw tiles have been grouped together in the form of compressed files (zip) comprising up to 9 raw tiles (representing a spatial extent of 1500 m × 1500 m). The assembly table with the zip files allows an overview of the grouped tiles. Point cloud - point classification The point cloud is classified into 9 different categories: [0] - Unclassified points [2] – Ground [3] - Low vegetation [4] - Average vegetation [5] - High vegetation [6] - Buildings [7] - Low Points (noise) [9] - Water [13] - Bridges, Footbridges, Viaducts [15] - Powerlines The number in [] indicates the Class ID.

In february 2019, the ACT has executed a LiDAR flight for the whole country. One of the results of this dataset is a digital height model. The public version is presented with a reduced resolution. For reasons of protection of certain sensible sites and the national archeological heritage, only a desensitized and with less resolution in the woods is made available to the general public.

This layer contains the official orthophotos covering the national territory of Luxembourg. The 4 surveying flights took place on 14, 19 and 20 June 2017, close to the solstice, with a sun position of > 35°. The ground sampling distance is <0,20m. The perspective displacement is in general <25%, except for Luxembourg-City, where it is <15% for a zone of 10x9km (90km2, centered on the coordinates 78000 east and 74500 north). On the borders, a zone of 50m behind the country border is included.

This layer contains the official orthophotos covering the national territory of Luxemburg, and that have been produced following a surveying flight in summer 2013 under the responsibility of the administration du cadastre et de la topographie.

This layer contains the cadastral parcels of the cadastral database. It cannot be shown together with geodata of another type of precision.

In february 2019, the ACT has executed a LIDAR flight for the whole country. Issued from the same flight, this aerial image (orthophoto) is primary for technical use.

This layer contains the infrared version of the orthophoto 2010.
