In statistics, more specifically in biostatistics, line-intercept sampling (LIS) is a method of sampling elements in a region whereby an element is sampled if a chosen line segment, called a “transect”, intersects the element.Kaiser, L, 1983. Unbiased Estimation in Line-Intercept Sampling, Biometrics 39. pp 965–976.

Line intercept sampling has proven to be a reliable, versatile, and easy to implement method to analyze an area containing various objects of interest.Buckland, S.T. Introduction to distance sampling: estimating abundance of biological populations, New York, Oxford University Press; 2001. It has recently also been applied to estimating variances during particulate material sampling.{{cite journal |last1=Dihalu |first1=D.S. |last2=Geelhoed |first2=B. |title=Principles of an image-based algorithm for the quantification of dependencies between particle selections in sampling studies |journal=Southern African Institute of Mining and Metallurgy |date=June 2010 |volume=110 |pages=323–330 |url=http://www.saimm.co.za/Journal/v110n06p323.pdf |access-date=18 November 2022 |language=en}}
