The line-transect technique is relatively easy to apply in the field, but the underlying theory and the mathematics involved are complicated, and consequently a computer and appropriate software are essential tools. The underlying theory has been described in a series of papers. The two most important papers were a monograph by Burnham et al. (1980), followed by the volume by Buckland et al. (1993), which documents the most recent developments in the science of line-transect methodology.
