Distance sampling is a widely used group of closely related methods for estimating the density and/or abundance of populations. The main methods are based on line transects or point transects. In this method of sampling, the data collected are the distances of the objects being surveyed from these randomly placed lines or points, and the objective is to estimate the average density of the objects within a region. (Wikipedia).

Intrinsic Persistent Homology [Ximena Fernández]
In this tutorial we study the usage of persistence diagrams in data that lie on a submanifold of the Euclidean space. We highlight the importance of the appropriate choice of distance in the input data, and we explore some estimators of geodesic distances computed from (possibly noisy) sam
