Abstract

This paper will describe the development of a method for measuring the point-to-point global geometric accuracy of a very accurate, large, drum scanner that has been recently developed for the cartographic market. The process described is used to verify the accuracy of a scanner whose media handling capability is 44 in. X 64 in. and whose accuracy specification is to be verified as better than .003 in. circular error throughout its entire scanning area. The technique developed is based on proper measurement fundamentals and is applicable to various types and sizes of scanning and plotting instruments.
