Digital Terrain Model (Standard ICAO)

In the scope of the International Civil Aviation Organization ([ICAO](https://www.icao.int)) requiring countries and airports to provide electronic Terrain and Obstacle Data ([eTOD](https://skybrary.aero/articles/electronic-terrain-and-obstacle-data-etod)), the Administration de la navigation aérienne has been tasked by the Government to take the steps necessary to comply with this requirement. This Digital Terrain Model (DTM) is the result of a first LIDAR survey flight that has been done in October 2017 and corresponds to the standards required by ICAO. For this reason this DTM also uses the international reference systems WGS84 and EGM2008. The data itself is split up in 4 different areas, which are specified as follows: - Area 1: The entire territory of Luxembourg; - Area 2: Terminal Control Area (this area is larger than the territory of Luxembourg); - Area 3: Aerodrome movement area; - Area 4: Category II or III operations (Runway 24). The different areas come with different numerical requirements, such as data accuracy and resolution.

背景概述

该数据集是卢森堡航空管理局为满足国际民用航空组织电子地形数据要求而创建的标准化数字地形模型，基于2017年10月的LIDAR测量，并采用WGS84和EGM2008国际参考系统。数据集覆盖卢森堡全境及周边航空管制区域，分为四个具有不同精度要求的区域，主要用于航空安全和导航目的。
