This is reached through a mapping device, and that is the smallest area of the map that could be delineated by only one boundary at the scale employed. In massive scale maps, very simple mapping models (narrowly outlined soil sequence) are delineated to achieve a purity of 80 per cent or maybe more inside การสำรวจดิน that device. But since the map scale decreases (from 1: twenty five,000 to 1: fifty,000. or one: 1,00,000), complex mapping units are employed. Techniques Employed in Soil Survey:
