On the Map there are a lot of 'unknown Outposts'

I want to create a new outpost

I know how to create a 'new' outpost via the tutorial
But can I take one of these unknown ones

What are they?

Do they have to be conquered?

unknown mean they are our of ur radar coverage and can therefor not be attacked, ether make a satelite scan or get a radar in the area

they are outposts that are outside radar range they cant be attacked

I have a Sat Scan build

But it is out of range

Do I need to build the next one in the Tech Tree
or upgrade the Sat Scan to reach that far away?

Also

When the game started, was the map blank?
And every Settlement and Outpost has been put there by a player

Meaning that the outpost I am trying to scan will belong to someone?

If so how do you settle one on a small Island?

For example Hawaii
The land is not wide enough to allow an outpost to be placed there as it is to close to water- Yet 4 Outposts are already there

as long as they are on land theyr are allowed, if you see any outposts on water tell admin, some on found a glitch.

and yes they are made by other people so they will try to defend them

and you need to use sat scan to get radar coverage in a area but it cost energy
