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.
