INSPIRE - Annex I Theme Coordinate Reference Systems

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当按照INSPIRE数据规范（INSPIRE DataSpecification）开展数据协调工作时，卢森堡的二维数据始终会通过ETRS89-兰伯特方位等面积投影（ETRS89-LAEA，http://www.opengis.net/def/crs/EPSG/0/3035）进行重投影。若需使用垂直坐标参考系（例如在附件二的INSPIRE高程主题中），则高程值将采用欧洲垂直参考系（EVRS，http://www.opengis.net/def/crs/EPSG/0/5730）进行表达。 以下数据集将以其原始坐标参考系ETRS89.UTM-32N（http://www.opengis.net/def/crs/EPSG/0/25832）作为附加信息对外提供：卢森堡国家高程控制点（卢森堡全国水准测量网NG-L）——这是覆盖全国领土的官方精密高程控制点网络，以金属测钉进行标定。
