| laser scanning reveals bryophyte canopy structure. | we evaluated laser scanning as a method to provide depth measurements for bryophyte canopies at fine spatial scales to derive surface roughness (lr), a structural parameter. depths to the first vertical canopy contact were measured on 5 x 5 cm2 areas of 27 bryophyte canopies using a contact probe, a commercial laser scanner and a scanner employing a laser diode striper (led scanner). laser scanning adequately distinguished structural types, but scanner configuration led to differences in the mag ... | 2005 | 15819931 |
