    forest canopy. With these words, they have generally as-serted that there can be different things—be they struc-tures, species, or environments—at different heights .   Canopy collections were undertaken over a total forest area of c. ha, with each soil type covering about half of this area. Our sampling was designed to capture . The effects of terrain, forest canopy, number of consecutive position fixes, and PDOP on accuracy were evaluated. Position accuracies were determined for a total of .
