The idea: Inscribed maps with radar cones, that can be reproduced, and placed on map walls.
Ways to execute it:
"Map Stamper": A block (like a cartography table) can be hooked up to a radar monitor, or multiple monitors, using the data links..
Then, with the block, maps (that contain the connected radar monitor/radars, it will stamp on the map, which will be like an ordinary map.
"Radar Map": A separate type of map, which can be placed in a cartography table, and will show all radars in the area, this could follow the same design philosophy as the others, and require to be linked to monitors (so you can't find out where enemy radars are), this is more give-and-take, but the main point is matching this with other maps.
I will admit, there is barely any way this is feasible in my mind, at least until Create 6 is compatible, so definitely look at it with scrutiny if it doesn't make sense.
For coding, I have no idea how this would be coded, I know I was a bit more eloquent with how I think it would work, but maps are out of my knowledge.
