./geography/gama, Geodetic network adjustment (surveying)

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.12, Package name: gama-2.12, Maintainer: gdt

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.

Upstream NEWS:

We are pleased to announce the release of GNU Gama 2.10!

One major update that is visible to the end users is the change in the
'update_constrained_coordinates' parameter. This parameter was
deprecated in 2.09 and has now been completely removed.

Another big change is the addition of output in GNU Octave format.
The GNU Octave *.m output file contains adjustment results from
gama-local, in matrix format that includes the following sections:

* General adjustment parameters - number of squares, observations,
  sum of squares, etc.

* IDs and coordinates of fixed points

* Information about the adjustment - adjusted and constrained
  coordinates, their indexes and covariances. Observation
  covariances and weight matrix and equation system matrices.

The main motivation for introducing GNU Octave output was to have an
experimental tool for computation of statistical parameters that are not
directly available in gama-local (e.g. reliability matrix).

GNU Octave output defines an explicit set of conditions to calculate the
adjustment of free networks (networks with a singular project equation
system). The differences between coordinates are tested with a tolerance
of 1e-3 millimeters.
This criterion may fail for poorly conditioned systems (typically
networks with a "bad"configuration).

Syntax of the GNU Octave .m output was tested for compatibility with
MATLAB R2013b (

Log message:
geography/gama: Update to 2.09:


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.


Version 2.08 December 2019

Maintainer's release

* new test data krasovsky-1926 with full reference in biblatex
  (renamed from bug-2019-04-23-oleg-goussev)

* new unit test for extern attributes in gama-local/scripts/check_externs.cpp

* new HACKING.md by Greg Troxel

* Legacy builds with expat-1.1 is available only as an testing option

* C++ sources cleanup mainly in lib/gama/local to conform with C++11

* C++11 standard is explicitly set in configure.ac (for testing C++14
  is set on in the alternative builds in the main CMakeLists.txt)

Log message:
all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.
