INSPIRE - Annex II Theme Orthoimagery - OrthoimageCoverage 2022 Infrared

This layer contains the official infrared orthophoto (infrared, red, green) from the 2022 surveying flights with a ground sampling distance of <= 10 cm per pixel (GSD). The absolute planimetric accuracy of the orthophoto can be given with a mean squared error MSE <= 20 cm. The perspective displacement is <= 25 %. The orthophoto covers the territory of the Grand Duchy of Luxembourg with an overlap of at least 50 m beyond the state border. The surveying flights took place with a sun position of >= 30 ° on August 10, 11 and 12 and September 1, 12 and 23, 2022.

Due to storage constraint, the raster image is made available in Luxembourg national projection (EPSG:2169) rather than European projection (EPSG:3035).
The raster in JP2 format can be downloaded from the URL provided in the INSPIRE GML under rangeSet/File/FileReference node or from the 'Source dataset' link in metadata information.

本图层包含2022年测绘飞行获取的官方红外正射影像（红外、红、绿波段），单像素地面采样距离（GSD，Ground Sampling Distance）≤10厘米。该正射影像的绝对平面精度满足均方误差（MSE，Mean Squared Error）≤20厘米，透视位移≤25%。影像覆盖卢森堡大公国全部领土，且向国境线外侧至少延伸50米以保证重叠覆盖范围。本次测绘飞行于2022年8月10、11、12日及9月1、12、23日开展，当日太阳高度角≥30°。

受存储条件限制，本栅格影像采用卢森堡国家坐标系（EPSG:2169）发布，而非欧洲坐标系（EPSG:3035）。

JP2格式的栅格影像可通过INSPIRE GML中rangeSet/File/FileReference节点提供的URL下载，或通过元数据信息中的“源数据集”链接获取。
