Unmanned aerial photogrammetric survey

Okay, kiddo! Have you ever seen a drone flying in the sky? Well, sometimes those drones are used to take pictures of the ground from up high. They take lots of pictures from lots of different angles to create a big picture of the land below.

This process is called photogrammetry. It's like putting together a puzzle, but with pictures instead of puzzle pieces. The drone takes all of these pictures and a computer program puts them together to make a map or a 3D model of the area.

But why not just use a regular camera? Well, drones can go places that humans can't, like really high up or over difficult terrain. Plus, drones can fly in a specific pattern to make sure they capture all the necessary information.

This type of photogrammetry is called unmanned aerial photogrammetric survey because no one has to physically be on the drone to take the pictures. It's all done by the computer and the drone.

This can be really helpful for all kinds of things! For example, people can use this type of survey to make maps for construction projects or to check on the health of crops on a farm. It's like having a super-powerful camera that can fly anywhere and create amazing pictures!
