Apzīmējumi:
db = double bark thickness (mm) – mizas dubultiezums (mm)
h = height from butt end of stem where bark thickness is to be calculated (cm) – augstums no stumbra resgaļa vietai, kur veicams mizas biezuma aprēķins (cm)
dbh = breast height diameter (mm) – krūšu augstuma caurmērs (mm)
dia = diameter on bark where bark thickness is to be calculated (mm) – caurmērs ar mizu vietā, kur veicams mizas biezuma aprēķins (mm)
lat = latitude (decimal degrees) – platuma grādi (decimālie grādi)
