AGL (Above Ground Level), Refers to height a UAV is flying above ground level.  For example, a drone flying 200 feet above a 70 foot hill would be 200 feet AGL and would then change to 270 feet AGL after flying over the hill.

In the drone industry, AGL stands for Above Ground Level. It refers to the vertical distance between a drone’s current position and the ground or an object directly below it. AGL is an important measurement used in various drone operations and regulations. Here are a few examples and technical aspects related to AGL:

  1. Altitude and Flight Planning: AGL is used to determine the appropriate altitude for a drone during flight planning. For instance, if regulations specify a maximum AGL limit of 400 feet, drone operators need to ensure their flight plans keep the drone’s altitude below this threshold.

  2. Obstacle Clearance: AGL is crucial for maintaining a safe distance from objects such as buildings, trees, or power lines. Pilots must consider the AGL when flying near or around obstacles to prevent collisions or unwanted interference.

  3. Terrain Awareness: Drones equipped with advanced sensors and navigation systems use AGL data to maintain awareness of the terrain below them. This information helps drones adjust their altitude, stabilize flight, and avoid collisions with the ground or uneven surfaces.

  4. Precision Agriculture: In the field of precision agriculture, drones can be used to monitor crops and collect data. AGL measurements help determine the optimal altitude for capturing high-resolution imagery or collecting sensor data to analyze plant health, crop yields, or other agricultural metrics.

  5. Inspections and Surveys: Drones are increasingly employed for inspections and surveys in various industries. AGL information assists in assessing the distance between the drone and the target object or structure being inspected, ensuring comprehensive coverage and accurate data collection.

Remember, specific AGL requirements and regulations may vary based on the country, region, or operation type. It’s essential for drone operators to be familiar with local regulations and guidelines to ensure safe and legal operations.
