GNU package GaMa is a C++ free software for geodesy released under GNU
General Public Licence. Project GaMa was started in 1998, in 2001 was
dubbed a GNU packaqe and today contains the following main components:

    [gamalib] C++ class library for handling geodetic observations
    (measurements) and points (coordinates), computation of
    approximate coordinates (needed for linearization) and adjustment
    of local geodetic networks in 3d.  C API to essential gamalib C++
    classes and functions is also available. Numerical solution of
    adjustment is based on orthogonal decomposition of the design
    matrix (ie without "normal equations"); currently supported
    algorithms are SVD and GSO (an algorithm based on Gram-Schmidt
    orthogonalisation). Adjustment on ellipsoid is developed in gama
    unstable version.

    [program gama-local] C++ program for adjustment of local geodetic
    network based on gamalib; format of input data is defined in XML. 

    [gmatvec] C++ matrix/vector template classes used in adjustment
    computations in gamalib.

    [rocinante] is a GUI for GNU GaMa based on Qt graphical library
    that is available for GNU/Linux under GNU GPL. Rocinante binaries 
    are also available for win32 platform; see 
              http://roci.sourceforge.net/
    for more information.
