A topographic map is intended to be a representation of the terrain. It differs from thematic maps (city maps, road maps etc.) by the richness of its content, its high precision and above all the representation of the topography by the contour lines. The cadastre and topography administration publishes topographic maps at the scales of 1:5,000, 1:20,000, 1:50,000, 1:100,000 and 1:250,000.

This layer displays the latest aerial image (orthophoto) available. An orthophoto represents a mosaic composed of digital aerial photographs geometrically rectified (orthorectified) and georeferenced in the LUREF national coordinate system. The digital orthophotos of the Grand Duchy are managed in the BD-L-ORTHO database which covers the entire territory of the Grand Duchy of Luxembourg and are accessible both on the national geoportal and on the open data portal (data.public.lu). Since 2016, ACT has carried out an annual survey of the entire country. Other aerial images are available under General public> Land cover> Aerial and satellite images.

The road map is a multi-scale digital map that contains transport networks, buildings, vegetation and hydrology. It is updated monthly and the new roads are entered at the same time as the changes on the cadastral plan. The road map uses vector tile technology, which gives you new possibilities to display the road map. The style editor gives you the choice between 3 editing modes: - Choose a predefined style: This editing mode provides you with a list of predefined colour palettes, which you can use to colour the map. - Modify the main colors: In this mode you can select an individual colour by theme. You also have the option of activating or deactivating a theme by checking the box. Advanced possibilities: This mode allows you to adapt the style of your map without restrictions. Using the Maputnik external style editor (https://maputnik.github.io/), you can make all kinds of modifications. When you are done editing, you can upload your style. The settings remain stored in your browser. When you are logged in, they are loaded into your profile so that they can be reused on another computer. Of course, the settings can also be used to create a custom background map and integrate it into your own website.

The hybrid map uses the most recent aerial image as background. In addition, it contains roads, street names and locality names.

This layer shows the restaurants open during the crises, and offering delivery and/or take away. It will be regularly updated based on the information we are getting through editus. If you manage a restaurant that offers delivery or take-away that is not on the map, please contact editus: https://www.partenaire-marketing.lu/fr/editus-initiatives-covid-19

This map shows the paths and roads that are closed to motorized traffic as part of the Velosummer in August.

National topographic map (vector format) based on the geospatial core reference data.

This layer contains the subdivision into tiles of the LiDAR data from the 2017 prototype. 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 on April 9, 2017 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.
