Well that's kind of why I asked! I have no real idea how to do it. At first I thought it was a simple case of working out the angle your viewing it from at the distance1600m but I don't know where to go from there...things 'appear' smaller to us as we move away from them and I hoped someone...

Is that directed to me Dave?

Hi Dave...thanks for sticking with me on this one! Ok so the height of my object is 38m high. As I move away from it the object 'appears' to get smaller and smaller until eventually it will vanish (even though it is still 38m high). So at a distance of 1600m away what height will the object...

how does this now relate to the height?

At the distance of 1600m the angle is 1.36°

Yes...sorry, I realized the object doesn't physically get smaller! Hence the title subject... I still don't know how to work this out - sorry! Do you know then what the perceived height will be if I travel 1600m from the base of the 38m high object?

Hi Dave, Yes if I'm stood under the object it is 35m high. But if I move away it gets smaller...so how tall will it appear in my vision at 1600m away? I can use trig to work out the height of an object from a certain distance but that gives the 'actual' height. I need the height my eye will see...

Hi There, Can someone tell me if I'm standing 1600m from an object that is approx. 38m high then what will my perceived height of the object be? Also will this remain the same if I am in an elevated position above the height of the object? Thanks!
