The LOS M-coverage (line-of-sight multi-coverage) map shows for all receivers within the area or region to how many transmitters the line-of-sight is not obstructed. Example of a LOS M-coverage map (without thresholds) where the receivers have been located with relative height, i.e., they are placed above the building blocks:
More information and the possibility to update or export the map can be accessed through the [Update] menu entry of the window, which presents, for instance, a dialog like:
The threshold values provide a mean to color the map with only four colors, where the actual color depends whether a certain receiver point sees at least that many transmitters.
