calculates the crownwidth according to the Bwinpro model; it expects a class stand
code = species Lower Saxony, d= diameter at breast height [cm]
it returns the crown width [m]
calculates the crownbase according to the Bwinpro model; it expects
code = species Lower Saxony, d= diameter at breast height [cm], h= height
[m], h100= top height [m]
it returns the crown base [m]
findd locates the relative height (0-1) for a given diameter, max. 50 Iterations or 0.05cm Differenz
relative height 0 is top of tree, relative height 1 is bottom of tree;
findd expects the arguments species code, dbh, and diameter to find height for
TreeGrOSS : class gendistribution generates a diameter distribution from stand values
This is the major class for several other classes of this package
http://treegross.sourceforge.net
TreeGrOSS : class generatexy creates random tree posistions, but distributes
them that there is a certain distance between them

TreeGrOSS : class growth calculates the dbh und height growth,
method bwinpro uses the growth model routines of Bwinpro

Version 21-SEP-2002
calculates the uniformheight curve value for a given species;
arguments, diameter of subject tree, diameter and height of middle tree,
species code Lower Saxony
young height, this is used up to an age of 25 years, and because there is no better data
The height development follow an expoteniell curve which meets the height h100 at 20 year of
age
calcultes the site index of a generated a diameter distribution from stand values
it uses all trees with no site index information at this point, parameters passed:
the stand, species code, age, mean quadratic diameter [cm] and height [m] of dg
TreeGrOSS : class siofdistrib calculates the Siteindex of a distribution
of the class gendistribution.java and stores that information for each tree
as an individual site index in st.tr[i].si

Version 18-Aug-2002
percentage of diameter differenciation, (see Td von Gadow), modified if next tree
is more than both trees height in distance away, then the difference is 1.0 because
there is a gap in the stand
percentage of height differenciation, (see Th von Gadow), modified if next tree
is more than both trees height in distance away, then the difference is 1.0 because
there is a gap in the stand
calculates the taper function according to the modell of Sloboda Uni Göttingen
species code according to the code of Lower Saxony; Parameter passed: species code,
relative lower bound (0= stem tip, 1= stem base), relative upper bound, dbh [m],
height [m]
