Unassociated Sims
Unassociated sims are large groups of sims that cannot be grouped into a continent, microcontinent or sim cluster. They have an average sim densoty and the sims that form them are not disposed into a Geometrical pattern (square, diagonal, lines). These kind of structures form the space between sim clusters or microcontinents and are a common feature of all Second Life oceans. An estimation is that the unassociated sims are about 30% of the total private-owned sims.
Some unassociated sims are a result of degradation of a former sim cluster of microcontinent. Some of them are formed another way, by creation, deletion and movement of sims.
It is impossible to make a map or a list of unassociated sims. Also, it is very difficult to group these structures.
