Working on a paper about Stockholm's earliest suburbs, I learn a neat old surveyor's trick. When surveying islands and shorelines, wait until winter when the water freezes over. Then you can have stationary surveying stations on the ice with unobstructed sightlines between them.
(This is no doubt taught in Land Surveying 101 at technical colleges to this day.)
