We are pleased to announce the release of GNU Gama 2.09.
There is one major fix visible to end users. Implicit value of XML
parameter 'update_constrained_coordinates' was changed to "yes". The
behavior of adjustment calculation was well and clearly described in the
documentation, but in some cases the old implicit value ("no") might
have led to poor numerical results. The input data XML parameter
'update_constrained_coordinates' is preserved only for backward
compatibility and is likely to be removed in some future release.
Several other minor internal issues were fixed, none of them visible to
end users.
About
GNU Gama package is dedicated to adjustment of geodetic networks. It is
intended for use with traditional geodetic surveyings which are still
used and needed in special measurements (e.g., underground or high
precision engineering measurements) where the Global Positioning System
(GPS) cannot be used.
Adjustment in local coordinate systems is fully supported by a
command-line program gama-local that adjusts geodetic (free) networks of
observed distances, directions, angles, height differences, 3D vectors
and observed coordinates (coordinates with given variance-covariance
matrix). Adjustment in global coordinate systems is supported only
partly as a gama-g3 program.
