Abstract:
DISTANCE (V2.0) estimates the abundance of biological populations.
Program TRANSECT and the program update DISTANCE are designed to analyze line transect data as
described by Burnham et al. (1980). Both perpendicular distances and
sighting angle and sighting distance data can be analyzed with TRANSECT or
DISTANCE.
Installation, operation instruction and examples of
