Network Coverage Map
Adds a map layer to show network coverage by passengers. This is actually something I have wanted for a long time and only just figured out how to do it.
How it works:
On selecting the map icon (first item in the "layers" tree -top left corner), it will gather data from the games own catchment area system, and work out which town buildings are within the catchment area of a passenger station and which are not.
It will then draw a rectangle around the perimeter of each each building, coloured green for buildings with coverage, and red for buildings without coverage. The result is not especially pretty, but it is very effective in indicating which buildings have coverage and which do not. (I would prefer to change the building colour, but that does not appear to be an option in the API).
Limitations:
To give acceptable performance I have made some optimisations:
-This checks for passenger station coverage only, and not whether the station has any actual service.
-The coverage map is not "real time", if you add a station you will need to toggle it on / off
Please let me know if the colours do not work for you, I could update this to be configurable.
Enjoy!
