Thread: 1000+ Rangefinders?

There is not enough difference to worry about in my humble opinion Rushy. I hear what you are saying though, the corners of the house will not be exactly where the measurement starts on the ariel shot. For LR purposes one would also have to keep in mind that the website is only measuring the true horizontal, so gradient would have to be factored in if required.
Also keep in mind that I paint houses for a living, so my tape reading is likely to be out

Horizontal distance more relevant to bullet drop anyway

Other factor with using something like that to measure is you need reasonably well-defined points on the aerial photo to measure between - hard to get an accurate distance from 'in the paddock' to 'in that other paddock over there'.
