OK, the broader question... and yes I know I could google all this but what fun is that?!
How do YOU estimate the tallest obstacle between you and a safe Return to Home?
There are of course a million variables... but at the same time, when you look at a forest in a landscape shot, all the trees are pretty much the same height.
So what's the average height of a tree?
A building averages 10' per floor so it's fair to estimate that a 5 storey building is at least 50'.
But I have no idea how tall a water tower is... or football uprights on the high school field... or telephone poles or high voltage lines.
So what do you do? Do you line up in front of an object with the camera level and use FPV to estimate height?
Do you google the height of common obstacles? Are you a natural at estimating vertical height?
There are a lot of references to estimate length on the ground but not so many references for upright things...
