GNU Gama is a project dedicated to adjustment of surveying and geodetic networks. It is intended for use with traditional surveying instruments, which are still in widespread use despite the advent of Global Navigation Satellite Systems. Traditional instruments are necessary for mm-level precision in local areas, and for underground or interior measurements. Gama also has some support for adjustment of networks containing GNSS observations.
Adjustment in local Cartesian 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.
As a GNU program, documenttion is available in texinfo format, resulting in a pdf manual and info pages.
Note that the version number of the package is defined in configure.ac.
Gama assumes a system complying with POSIX, and a compiler that spports C++11. Gama intentionally avoids C++14 or later constructs for improved portability.
Beyond that, the standard autotools instructions, available in INSTALL, apply. Note that Gama's tests may be run via "make test".
