Fly: When the drone is in flight it does the work of capturing the right kind of photos for you. Not only this, the drone is also capable of geo-tagging the photos, so that you may know which photo belongs to which area. You may be surprised how the technology has advanced as the takeoff and landing both have become automated in newer model drones. This has become possible due to inbuilt features like “return to land”.
Process: Processing involves stitching the photos together. The stitching must be done in a precise and crisp manner. The pixel size will depend on the height from which the photo was taken but the most desirable size of the photograph is the high resolution map with one cm per pixel.
