AI scouting rules?

[teelaurila]

So what exactly do I need to do to keep the AI from scouting my city? Normal LOS apply? In this particular case wraith settlers are seeping across the sea, so I need to keep them away from squares neighboring my cities?

Yes, normal scouting range applies, so depending on what type of units, you need to keep them at a distance of at least 2, 3, etc...
