Distance Overlay
The Distance Zone Overlay is an overlay which can be used for displaying zones around buildings. 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 building(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 Use cases Distance Overlay page.
Additional information displayed in hover panel
When clicking on a specific location in the map, the hover panel gives additional information of the distance from the clicked location to the object which has a distance zone.
If the "Count Hits instead of Distance" option is enabled, the overlay show the number of overlapping zones on the clicked location.
Variants
The following overlays that previously were separate entities can now be constructed using a general distance overlay:
- Safety Distance Overlay
- HIT_COUNT; When this option is selected, the functionality of this overlay changes to counting for each grid cell how many objects are within the defined distance of those objects. Which objects are considered depends on the configured rasterization and whether they have a distance defined that is larger than 0.
