I can't figure out one light pollution source in Poland in Sluchowo (54.77550N, 17.94972E). The map from 2015 shows some factory of sorts, but it disappears on the map from 2020, all you can see is an outline what it was. I really wonder what kind of place this was and why it emitted relatively a lot of light.

Most likely some kind of military operation. It could be a storage site, guarded 24/7 where light is important so the guards can see everything clearly.

Is this just tradition? Surely a computer system can see/hear, maybe using night-vision (lidar? radar?), way better than guards can. Then lights can activate and guards can shoot at anyone unwanted who crossed the perimeter .. surely enough incentive?

I think that being well lit will help to deter intruders.

[pbhjpbhj]

How? Won't getting shot my soldiers be a deterrent?

[zoonosis]

How will they know if there are soldiers if they aren't lit?

OpenStreetMap doesn't have anything there, but Wikimapia has a ‘Shale Gas Drilling Rig’ nearby (‘Wiertnia Gazu Łupkowego’).
