in the US, it's a distinct possibility that a farmer in Iowa might buy
a 200 acre field and plant it 1/2 corn, 1/2 soybeans and rotate
which half is which from year to year. so do you want to map fields
as legal ownership, which is one boundary, or as sections which are
planted differently from each other, which is another?
