With a Phantom 3 Professional camera pointing straight down at the ground, what are the dimensions of the area on the ground that I can see at various altitudes and at 4K and 1080p for videos and for still photos at 16:9 and at 4:3 aspect ratios respectively?
Is there a formula that can be used - or a chart that can be referred to?
I want to plot a search grid with little to no overlap and obviously, the higher up you are, the more ground you can see but I'm curious what the actual numbers are.
I do know that there are several ways I could determine this via taking pictures from the various altitudes and then measuring the visible areas - I was hoping there might be an existing chart or formula that would save me the trouble.
