Aerial mapping drones are a technology that is starting to be used more and more because they can do the job quicker and much cheaper than other methods. The biggest reason is that all the equipment that can be attached to these drones. It makes the process automatic, as the drone can collect all the data with these measuring devices, and then simultaneously send it back to a computer where people can further analyze it. There are two main methods used in aerial mapping with drones: photogrammetry and LiDAR. Here’s some information about them, and the benefits that using each provides. LiDAR Short for Light Detection and Ranging, LiDAR uses lasers to measure distances relative to the ground level. To explain it as easy as possible, it emits laser beams at a set frequency and down to ground level. Once it hits the target being measured, it returns the laser back to the drone. This time difference can then be used to calculate the distance relative to ground level. It may be a little complicated, but that’s how it basically works. Everything needed for a LiDAR instrument can be attached at the bottom of a drone and then flown over […]
