In statistics, 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.[1]

Line intercept sampling has proven to be a reliable, versatile, and easy to implement method to analyze an area containing various objects of interest.[2] It has recently also been applied to estimating variances during particulate material sampling.[3]
