There are several benefits of this surveying method. Let's see some of them.
Drone photogrammetry requires minimal equipment and training, which reduces costs.
As technology develops, drones are becoming available to almost anyone. With a few hundred dollars invested in a drone, you can get exact surveying data without hiring people and aircraft.
Detailed and precise data
One of the best things about drones is they can fly lower than airplanes. That allows for collecting maximally accurate info (up to 1 cm-0.4 inches).
Reduces safety risks
Drone photogrammetry can access unreachable terrains. In that way, workers don't need to go there, which is essential for their security.
Practical and versatile
Drones can carry various equipment, such as cameras, thermal cameras, sensors, etc. They can gather data for different purposes, such as 3D modeling, mapping, and surveying.
Resistant to weather conditions
These helpful devices can operate in rain, snow, and moderate winds, which makes them highly efficient.
