style proposition to selecting spatial sample for estimation unknown point

Abstract

This paper research about method choice a samples in spatial statistics and using this samples in estimation operation in non-measured area , since there tow types from spatial samples which concluded take up in this paper as a point sample and area sample , since for any type method for choice him , that after definition bounded statistics which have terms this sample it is necessary to be in spatial space , and we using kriging technique in estimation operation in non-measured , moreover calculation kriging estimator variance and kriging variance .we application this paper on our country (Iraq) from (15) governorate in field farming wheat and it is real data, then we programmed all results of mathematical operation by matlab language.
