I suspect I did not describe the situation well enough. The park is 2.4 ha.
There are some fixed benches in some parts of the park and cca 50 moveable
ones in the main area, where there are no fixed benches. The moveable
benches line three paths in somewhat irregular intervals of about 10m. I
suspect the benches are moved by a few meters by the gardeners in order to
spread out the wear on the grass underneath them and make it easier to mow
the grass. While the benches line both sides of about 250m of paths, they
don't move too far from their original positions.
The current situation is that the benches are mapped according to some
ortho. While inaccurate, I still think that describes the current situation
better than some area.
