The network parameters may be listed with the following optional
attributes of an empty-element tag <parameters />
sigma-apr = "10"
value of a priori reference standard
deviation—square root of reference variance (default value 10)
conf-pr = "0.95"
confidence probability used in statistical
tests (dafault value 0.95)
tol-abs = "1000"
tolerance for identification of gross
absolute terms in project equations (default value 1000 mm)
sigma-act = "aposteriori"
actual type of reference standard deviation
use in statistical tests (aposteriori | apriori
); default value
is aposteriori
update-constrained-coordinates = "no"
enables user to control
if coordinates of constrained points are updated in iterative
adjustment. If test on linerarization fails (see section Test on linearization),
Gama tries to improve approximate coordinates of adjusted points and
repeats the whole adjustment. Coordinates of constrained points are
implicitly not changed during iterations.
algorithm = "gso"
numerical algortihm used in the adjistment
(gso, svd, cholesky, envelope).
languade = "en"
the language to be used in adjustment output.
encoding = "utf-8"
adjustment output encoding.
angles = "400"
output results angular units (400/360).
latitude = "50"
ellipsoid
cov-band = "-1"
the bandwith of covariance matrix of the
adjusted parameters in the output XML file (-1 means all covariances).
Values of the attributes must be given either in the double-quotes
("…"
) or in the single quotes ('…'
). There
can be white spaces (spaces, tabs and new-line characters)
between attribute names, values, and the equal sign.
