The buildings are modeled on the basis of a photogrammetric exploitation of the aerial images of 2017. The definition of the LOD 2.3 used includes a detailed modeling of the shape of the roofs (without details like skylights, chimneys, antennas, solar panels, ...) with a vertical projection to the ground. These data can be consulted in the 3D web viewer of geoportail.lu. This type of building modeling is not yet available for the entire country. As part of the LiDAR pilot project in 2017, this building modeling was carried out over an area of ​​3 km2 (2 km2 in Diekirch and 1 km2 in Bastendorf). The origin of these data restricts the separation of units at the building block level. The exploitation of aerial images for the modeling of 3D surfaces does not allow a distinction of units by cadastral parcels. (Eg terraced houses) The data is available as CityGML files https://www.opengeospatial.org/standards/citygml, a standard format for exchanging 3D data. Data not transformed into INSPIRE data model

Daily pollen concentration data for 33 pollen types since Jan 1, 1992 in Luxembourg. The view service of this dataset support time requests. The different wms shows value of measurements at a precise timestamp.

The buildings are derived from data from the topographic database (BD-TOPO-L) of the Cadastre and Topography Administration, based on 2013 aerial imagery. Data of type LOD 1 (Level of detail 1) represents simple blocks without details on roofs. The height of the blocks is defined by the average height of the outer perimeter of the roofs from photogrammetric measurements (i.e. the extraction of horizontal (X, Y) and vertical (Z) information based on aerial images) . The survey of these roof perimeters is part of the 2013 topographic survey for the updating of the topography database (BD-TOPO-L). The origin of these data restricts the resolution of units at building block level, smaller units such as annexes or remarkable building parts (e.g. church towers) are indistinguishable. The data is available as CityGML files, a standard format for exchanging 3D data. Buildings can be downloaded as ZIP files by municipality (+/- 10 MB / MB per file), by canton (+/- 40 MB / MB per file) or for the whole country (+/- 600 MB / MB). The data are projected in LUREF (EPSG: 2169), ie a coordinate reference system using values ​​in meters [m]. Data not transformed into INSPIRE data model

The chemical status of the surface water bodies is assessed as being good or failing to achieve good chemical status. The assessment of the chemical status for the second river basin management plan is based on the list of substances of directive 2008/105/EC and the environmental quality standards established by the new directive 2013/39/EC.

Evaluation of the quality element “continuity” per surface water body

The WFD's quantitative status objectives aim to ensure a balance between groundwater withdrawal and recharge.

Phytoplancon is one of the 4 biological quality elements (BQE) for the assessment of the ecological status of the natural water bodies. The evaluation of this BQE is only relevant for the large rivers where the quantity of phytoplancton is significant and can be evaluated. The natural water bodies of typology VI present significant phytoplancton concentrations to allow an assessment. Some of the heavy modified waterbodies (HMWB) present significant phytoplancton concentrations too, these are the HMWB Sûre (WB III-2.2.1) and the HMWB Our (WB V-1.2). The annual frequency for phytoplancton monitoring is 6 samples between April and October.

The ecological status of the natural waterbodies is assessed in 5 classes going from 1 to 5 (high, good, moderate, poor, bad). The classification of the ecological status is based on the biological quality elements, physico-chemical quality elements and in some cases also the hydromorphological quality elements.

This dataset contains the current Statistical Units of the Grand-Duchy of Luxembourg. It represent the municipalities with a LAU2 code valid since 01-01-2024 until today. The dataset is structured according to the INSPIRE Annex III Theme - Statistical Units. The data has been derived from the "LIMADMIN" data.

A medium combustion plant is any technical device with a rated thermal input of 1 MW or more and less than 50 MW in which combustible products are oxidised in order to use the heat thus produced, such as combustion plants, engines and gas turbines. All medium combustion installations must be registered with the Environmental Administration, which keeps a public register with information on each installation. The operating conditions and the obligations of the operators of these installations are laid down in the Grand-Ducal Regulation of 24 April 2018 on the limitation of emissions from medium combustion installations.
