Höjdövervakning
Höjdövervakning refers to the process of measuring and monitoring the elevation or altitude of objects, terrain, or the atmosphere. This can be achieved through various methods and technologies, depending on the specific application. In geodesy and surveying, it involves determining the precise vertical position of points on the Earth's surface, often using techniques like leveling, trigonometric heighting, or global navigation satellite systems (GNSS). For aircraft and spacecraft, altitude monitoring is critical for navigation, collision avoidance, and safe operation, utilizing instruments like altimeters.
In environmental science and meteorology, höjdövervakning plays a role in tracking atmospheric layers, cloud heights, and
