Hi, Please have a look at this farmland area:- Way: 1408604413.  It has several self-intersections, making it not a true outline.

I also see narrow margins between land areas, ie between Way: 1408604413 and Way: 1396818871. These areas would join at the common boundary, (usually the hedge line), thus not leaving a narrow margin of undefined land.

I usually just correct these problems as I see them, but I've not corrected the above so that you can see what I mean.

Regards Bernard.
