13.1 - Density Estimation Methods for Line and Point Transects13.1 - Density Estimation Methods for Line and Point Transects
Line transect sampling is usually used to sample objects for which detectability depends on location relative to the observer.
The objective is to estimate the density of objects in the study region.
Examples include birds, mammals, and plant species.
Here is a picture for line transect method.
In the following sections, we will introduce the Narrow-strip method, the smooth-by-eye method and parametric methods.
