I think this should create a hollowed out polygon. But it creates a solid polygon. How could I use Well-Known text tocreate a hollowed out shape? I know I can ceated 2 polygons and
.GetDifference which creates a MultiPolygonShape which is hollowed out but I am trying to use industry standard stuff. Thanks
MULTIPOLYGON(((-21.875 10.625,21.875 10.625,21.875 -10.625,-21.875 -10.625,-21.875 10.625),(-20.625 9.375, 20.625 9.375,20.625 -9.375,-20.625 -9.375,-20.625 9.375)))
