When harmonizing data according the INSPIRE DataSpecification, the 2D Luxembourdish data are always reprojected using the ETRS89-LAEA (http://www.opengis.net/def/crs/EPSG/0/3035). When a vertical CRS is needed (for instance in the INSPIRE theme Elevation of annexe II), the height is expressed using the EVRS (http://www.opengis.net/def/crs/EPSG/0/5730).

The following datasets are made available as additional inforamtion in their original CRS ETRS89.UTM-32N(http://www.opengis.net/def/crs/EPSG/0/25832): The National Height points of Luxemburg (Nivellement général du Luxembourg NG-L) : official network of precision height points, covering the entire national territory and materialised by metal studs
