In terms of aerial measurement, what does AGL stand for?

AGL stands for Above Ground Level in the context of aerial measurement. This term is commonly used in aviation, drone operations, and geographic information systems. AGL refers to the altitude of an object or measurement in relation to the ground beneath it, rather than a fixed reference like sea level. This is crucial for sUAS (small Unmanned Aircraft Systems) operations, as it helps operators understand how high they are flying above obstacles, such as trees or buildings, which is essential for safe navigation and compliance with regulations.

Understanding AGL is fundamental for assessing the safety of sUAS flights, as it directly affects how the drone interacts with the environment. Pilots need to consider AGL when planning flights, particularly in areas with variable topography or urban environments. Accurate AGL readings ensure that drone operations maintain a safe distance from the ground and any potential hazards, thereby minimizing the risk of accidents.
