The Geoportal of the Grand Duchy of Luxembourg is the official national platform for accessing government geodata, maps and related services. It brings together information for individuals, professionals and developers, covering subjects such as land parcels, topography, infrastructure, the environment, water, agriculture, housing, tourism and spatial planning. Users can explore public data through map portals, a 3D viewer and searchable data catalogues, including open data, web services and INSPIRE resources.

The platform also provides practical tools and services for finding addresses and cadastral parcels, viewing parcel history, planning routes, calculating distances and converting coordinates. Users can order cadastral extracts, surveying files and aerial images, while professionals can access specialized portals and export parts of the official 3D model. Additional features include hiking information, agricultural and biodiversity maps, and a tool for creating 3D-printable files for areas in Luxembourg. Developers can integrate Geoportal data and functionality into external websites through its Map API. The site is associated with ACT and offers information in several languages.
