Digital Terrain Model (Standard ICAO)

In the scope of the International Civil Aviation Organization (ICAO) requiring countries and airports to provide 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. Follow the links in the description or consult metadata for further Information.

在国际民用航空组织（ICAO）要求各国和机场提供电子地形与障碍物数据（eTOD）的框架内，航空导航管理局受政府委托采取必要措施，以确保符合该要求。本数字地形模型（DTM）是2017年10月进行的一次首次激光雷达测量飞行所得成果，符合ICAO所要求的规范。因此，本DTM亦采用了国际参考系统WGS84和EGM2008。数据本身分为四个不同的区域，具体如下：区域1：卢森堡全境；区域2：终端控制区（该区域面积大于卢森堡领土）；区域3：机场运行区；区域4：II类或III类运行（跑道24号）。不同区域对应着不同的数值要求，例如数据精度和分辨率。请参考描述中的链接或查阅元数据以获取更多信息。
