GNU Gama package is dedicated to adjustment of geodetic networks. It is intended for use with traditional geodetic surveys 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. https://www.gnu.org/software/gama/ Here are the compressed sources and a GPG detached signature[*]: https://ftp.gnu.org/gnu/gama/gama-2.14.tar.gz https://ftp.gnu.org/gnu/gama/gama-2.14.tar.gz.sig Use a mirror for higher download bandwidth: https://ftpmirror.gnu.org/gama/gama-2.14.tar.gz https://ftpmirror.gnu.org/gama/gama-2.14.tar.gz.sig Here are the MD5 and SHA1 checksums: 3dd159118352a7ff2bac137b32c5fff4 gama-2.14.tar.gz 149f6df78b8220c9d55d97115792305af0af16f8 gama-2.14.tar.gz [*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify gama-2.14.tar.gz.sig If that command fails because you don't have the required public key, then run this command to import it: gpg --keyserver keys.gnupg.net --recv-keys 1b77fc09 and rerun the 'gpg --verify' command. NEWS This is a maintainer release. Changes in release 2.14 (2021-02-28) * fixed html output format. The html format in GNU gama was correct, but in Qgama the table of adjusted coordinates with colspan attributes the Qt widget QtTextEdit rendered the table wrong and all <td> tags had to be written explicitly. -- If you have a working or partly working program that you'd like to offer to the GNU project as a GNU package, see https://www.gnu.org/help/evaluation.html.
