Simple mark-recapturewe assume we know it, and with distance sampling methods (Chapter 7) we assume “capture” is certain on the line or point. Depending on the application, these assumptions may be quite reasonable; when they are not, removal or mark-recapture methods can be useful.

Nearest neighbour and point-to-nearest-objectint-to-nearest-object sampling, points within the survey region are randomly sampled, and the distance from each point to the nearest object is measured. If we assume that objects are independently and uniformly distributed throughout the survey region, then the distribution of nearest-object distances is the same under both approaches.
