Using trigonometry to calculate pixel size in aerial imagery

Have you used trigonometry other than in your school maths class? Take a watch Karen Joyce at She Maps explains how we can determine pixel size from our aerial equipment height.

Ever wondered why you had to study trigonometry at school? For exactly this purpose is the answer! I explain how to work out the pixel size for any given flying height for a drone.
