| Abstract: | Adopting a principle of “check-accept for the first rank, inspection for the second rank”, this paper briefly discusses the
rationale of the sampling inspection and the sampling inspection schemes to digital products in GIS. The OC curve is drawn
to explain the deficiency of the percent sampling inspection. Meanwhile, the method of One Time Limiting Quality of count
selection is presented as the inspection scheme for production departments while the method of One Time After-inspection Mean
Percent Defective Upper Limit of count selection is for acceptance departments.
