The primary reason for flying a drone above 120 meters is to capture better resolution images for surveys, particularly in areas that require higher altitudes to gather comprehensive data over large geographical areas. When drones operate at a greater height, they can cover more ground in a single flight, allowing for a more extensive perspective and improved data collection for tasks such as topographical mapping, agricultural assessments, and infrastructure inspections.

In surveying, flying at higher altitudes can minimize the angles of distortion in the images taken, contributing to clearer and more detailed aerial photographs. This is particularly important when the objective is to create accurate models or maps, where detail and clarity are paramount.

While the other options touch on important applications of drone technology, they do not directly relate to the inherent advantages of capturing high-resolution imagery from elevated altitudes.
