G'Day Folks,
My problem:
I am mapping vegetation communities (as regions/polygons) and some regions
need to contain other regions (like a hole (one region) in a donut (the
other region))...
Is there a way I can create a region/polygon which has a "hole" cut out of
it and is combined with the outer region so that calculations of area
exclude the "hole"?
Many many thanks in advance,
Ian
