FIG. 8. The spectral reflectance factors obtained for pine on two 
site types: VT (Vaccinium myrtillus type) and Ptkg (pine 
growing dry swamp). The curves are averages of 9 sample 
plots each.

The spectral reflectance factors obtained for timber volume 
classes of pine. The curves are averages of 9 sample plots 
for the class 0-70 m3 , 7 plots for 71-140 m? and 6 plots for 
over 140 m».
