Abstract

Area frame sampling has been widely experimented in many fields, such as agricultural survey or forest inventories. In many cases sampling units are area elements of a certain predetermined size. The choice of this size is an important element for the cost-efficiency of the sampling design. Sampling units can be often considered as a cluster of smaller units on which information is available for a covariant, such as the same magnitude to be evaluated in a previous date, or a land cover map with a certain degree of approximation.
