Abstract

This paper explores the effect of correlation on the statistics of separation of two lines when using regularly-spaced offsets. In a case study the positional accuracy of a test coastline feature is determined with respect to a representation of the same coastline at a much larger scale using regularly-spaced perpendicular offsets. The paper uses two methods to show how adjacent offsets are correlated and how this degrades the precision with which the positional accuracy of the test coastline can be determined. These methods and findings make offset models of positional accuracy for linear features more explicit and attractive.
