Updated to 1.1 by me all credit go to murdat https://mods.factorio.com/mod/Roboport_Radar
Intended for use with Brave New World.
Provides Coverage for a roboport's construction area.
This is achieved by adding a radar to each roboport that Charts all chunks within the roboport's construction radius once every 3 seconds.
The added radar does not perform Long Range Survey Scanning, you will need a real radar for that.
