This really is obtained by the use of a mapping device, that is the smallest location of the map that may be delineated by just one boundary at the size utilised. In massive scale maps, very simple mapping units (narrowly defined soil sequence) are delineated to attain a purity of 80 per cent or maybe more in just that device.
