How should they be mapped. Eilean Bàn at Kyle looks similar.
> * Many of the coastlines are uncorrected PGS data often with
> systematic errors of placement of 100s of metres.
> * In some cases shadows on high cliffs have led to erroneous
> coastlines (notably Soay which should now be corrected).
> * The Western Isles boundary largely does not follow the coastline.
> It appears to mainly result from import of Boundary Line Open Data
> and therefore uses the low water mark. This data is generally more
> accurate than coastline data so many islands fall outwith or
> across the admin boundary.
> * Many islands are not actually part of the boundary relation at all.
Is it right and the other small ones wrong. Is there a wiki?
