GNU Gama
GNU Gama is a project 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 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.
Requirements
For parsing XML documents Gama uses XML parser expat
,
originally written by James Clark. If for any reason expat
library is not installed on your system, Gama still can be compiled
and build with old version 1.1 of expat
, that is distributed
with Gama (make dep-expat-1.1; make
).
XML parser expat
is not a part of GNU Gama,
but is used with GNU Gama.
GNU Gama requires adjustment input data described in XML format, see documentation for details.
Download
GNU Gama can be found in the subdirectory
/gnu/gama/
on any of GNU FTP server mirrors http://ftpmirror.gnu.org/gama or checked-out
from the GIT server. See our project page at http://savannah.gnu.org/projects/gama/
for more information.
To get an anonymous read-only access to the GIT repository for the latest GNU Gama source, issue the following command
git clone git://git.sv.gnu.org/gama.git
If you are interested in an alpha version of Qt based GUI, build the application following the six steps given bellow
git clone git://git.sv.gnu.org/gama/qt.git cd qt/gama-q2/lib/ git clone git://git.sv.gnu.org/gama.git cd ../.. qmake make gama-q2/gama-q2 &
The collection of sample networks is available separetely. To checkout the gama-local
examples from GIT use the
command
git clone git://git.sv.gnu.org/gama/examples.git
GNU Gama files in GIT repository can also be downloaded and browsed in directories gama, qt and examples. For example the master tar ball can be downloaded from
http://git.savannah.gnu.org/cgit/gama.git/commit/
Builds for Windows
Command line executables for Windows are available from https://sourceforge.net/projects/gnu-gama-builds/.
Documentation
A manual is available online in several formats.
