Elevation plot between two geographic locations

That HeyWhatsThat site is really nice, gone straight in my bookmarks for next time I want to retroactively work out where the horizon was when hillwalking. Shame it can't pick up big man-made structures too though, I know what a colossal and time-variable dataset to include that would be though. When one is on a hill looking over a plain then TV masts, power stations, wind farms and church towers often form the most noticable points one hopes to be able to use to identify which areas on the flat terrain one is looking at.

It looks like the earth's curvature is highly exaggerated.

May just be the result of the vastly different scales on the X and Y axes? ~80km horizon distance seems about right to me.

Actually, that's right. It is just over 100m. :-X
