You could use an expensive laser rangefinder with height capability, or as you see in the video, we use the drone to determine obstacle height. If you have a bunch of trees, buildings, poles, whatever, these are the steps you follow to determine their height.
1. Look at your objects and determine which one looks the highest.
2. Start your drone off at the lowest point that you’re going to be flying.
3. Ensure your drone displays a height of “0” at this ground point.
4. If the object is above the horizon, you’re going to have to fly higher.
5. Fly your drone up so that the object is just below the horizon.
6. Look at your drone’s display to see what height the drone is at.
7. Repeat for any other obstacles on your site that you need to check height for.
8. There you have it! Your object will be at or just below that height!
Now that you know the height of your obstacle(s), start flying above them with peace of mind that you’re not going to crash into one of them. At what height you fly above objects is completely up to you! Some might want to fly at at least 30′ above any objects, while others are comfortable with flying much closer. Whatever you chose, make sure it’s within your skill set, and something that you’re comfortable with.
Alright, get out there and start flying! If you have any questions that you’d like answered in a video like this, be sure to ask us here and we’ll show you how it’s done! Remember, we’re The Drone Trainers, and we don’t just talk about how to do things with your drone, we actually show you how to do it! See you again soon!
