It is hard for me to imagine a way of employing detection function parameters from a line transect survey in a point transect survey. Recognise there are two processes giving rise to detections: 1) the distribution of animals with respect to the transects and 2) the filtering of those animals by the detection process. Process 1) differs between lines and points; animals are assumed distributed uniformly at all distances with line transects, but with points, geometry argues there are few animals available to be detected at distances close to the observer and large numbers of animals available to be detected at large distances from the observer. I would be reluctant to apply a detection function from a line transect survey to a point transect survey.
Perhaps other boffins have alternative
thoughts.
