Distance Overlay

What the Distance Zone Overlay is

Distance Zone Overlay

The Distance Zone Overlay is an Overlay which can be used for displaying zones around constructions. One use case for this could be a zone around a wind turbine that resembles the noise contour. The distance zone is always a circle situated around the affected construction(s). The radius of this circle can be adjusted in the function value tabel. See below for more information on how to adjust the function value. The overlay can also be modified to count how many zones are overlapping each other. See below for more information on how to enable this "Count Hits instead of Distance" option. An example use case for this overlay can be found on the Usecase Distance Overlay page.

If the "Count Hits instead of Distance" option is enabled, the overlay show the number of overlapping zones on the clicked location.
